Insulin-dependent diabetes mellitus (IDDM), or type I diabetes, is the end result mainly of a T-cell mediated autoimmune destruction of pancreatic islet beta cells.
|
34 |
1485949
|
The DQ molecules involved in IDDM susceptibility or protection may exert their function either during thymic development of potential self-reactive CD4+ T cells, or by preferential presentation of certain beta-cell derived peptides to CD4+ T cells, or both.

Treatment with IL-1 alpha also inhibited insulitis and hyperglycemia induced by adoptive transfer of pathogenic, polyclonal CD4+8- T cells.
|
36 |
1510786
|
Even after islet-cell destruction, IL-1 alpha injections in diabetic NOD mice normalized plasma glucose levels when administered in combination with insulin, whereas equivalent levels of IL-1 alpha alone did not.
|
37 |
1510786
|
Thus, IL-1 treatment could clinically be an effective immunotherapeutic modality for autoimmune diabetes mellitus by suppressing early disease progression or normalize plasma glucose levels when insulin is present.

|
For the precise analysis of the roles of CD4+ and CD8+ T cells in the pathogenesis of this mouse, these subsets must be transferred into recipients that are completely free of T cells and pathological changes.
|
40 |
1516628
|
To the nude recipients we transferred either one of a highly purified CD4+ or CD8+ T cell subset derived from non-diabetic female NOD mice; any in vivo increase in the contaminating T cell subsets was prevented by injecting the antibody homologous to it.
|
41 |
1516628
|
However, the subsequent transfer of CD8+ T cells into CD4+ T cell-reconstituted recipients induced severe insulitis and hyperglycemia in almost all the recipients.
|
42 |
1516628
|
In these diabetic recipients, we observed severe damage of the pancreatic islets and the infiltration of a large number of CD8+ T cells into the remaining islets; insulin-secreting beta cells were no longer detected.
|
43 |
1516628
|
These results suggest that CD4+ T cells play a predominant role in the development of insulitis and that CD8+ T cells migrate into the islets and are subsequently, with the aid of CD4+ T cells, differentiated into killer cells which act against beta cells.

The peripheral blood lymphocytes from patients with insulin-dependent diabetes mellitus (IDDM) and healthy controls were analysed for the HLA-DR+, interleukin-2 receptor-positive (IL-2R+) activating antigens, and for CD45R+ and CDw29+ subsets from the purified CD4+ and CD8+ T cells populations.
|
189 |

Genes encoding tumor necrosis factor alpha and granzyme A are expressed during development of autoimmune diabetes.
|
365 |
2179951
|
We show that the genes for tumor necrosis factor alpha and granzyme A, a serine protease associated with cytoplasmic granules of cytotoxic cells, are expressed during the development of spontaneous diabetes mellitus in the nonobese diabetic mouse.
|
366 |
2179951
|
Tumor necrosis factor alpha expression is exclusively observed in the intra-islet infiltrate, predominantly in lymphocytes adjacent to insulin-producing beta cells, the targets of the autoimmune destruction, implying that tumor necrosis factor alpha expression is induced locally--i.e., in the islet.
|
367 |

|
A considerable portion of cells expressing tumor necrosis factor alpha appear to be CD4+ T cells.

Repopulation of the atrophied thymus in diabetic rats by insulin-like growth factor I.
|
369 |
2187189
|
We describe here that the weight and the architecture of the thymus of diabetic rats is restored towards normal not only by insulin but also by insulin-like growth factor I (IGF-I) treatment.
|
370 |
2187189
|
In contrast to insulin, this effect of IGF-I occurs despite persisting hyperglycemia and adrenal hyperplasia.
|
371 |
2187189
|
Insulin, as well as IGF-I treatment of diabetic rats increased [3H]thymidine incorporation by thymocytes.
|
372 |
2187189
|
In addition, a major deficiency of thymocytes expressing simultaneously the W3/25 and the Ox8 antigens (corresponding to immature human CD4+/CD8+ thymocytes) was observed.
|
373 |
2187189
|
These changes were restored towards normal by insulin as well as by IGF-I treatment.
|
374 |
2187189
|
We conclude that IGF-I has important effects on the thymocyte number and the presence of CD4+/CD8+ immature cells in the thymus of diabetic rats despite persisting hyperglycemia.

In order to address the roles of CD4+ and CD8+ T cells in pancreatic islet rejection, we used an adoptive transfer model in which H-2b nude mice were reconstituted with negatively selected H-2b CD4+ or CD8+ T cell subpopulations and engrafted with fully allogeneic pancreatic islet grafts.
|
404 |
2506278

Whereas metabolic derangement before the initiation of insulin treatment led to small but significant decreases in the percentage of CD4-positive lymphocytes as well as of the activity of natural killer (NK) cells and antibody-dependent cellular cytotoxicity (ADCC), the administration of CyA did not influence any of the immunologic parameters tested, which included proliferative lymphocyte responses to mitogens and alloantigens and serum concentrations of immunoglobulins G, A and M.

Immunohistological studies using monoclonal antibodies showed that infiltrating MNC consisted mainly of CD4+ T cells ( > 75% of leukocytes) plus smaller numbers of macrophages and CD8+ T cells.
|
538 |
7485382
|
These cells displayed evidence of immune activation with expression of receptors for interleukin-2 (IL-2R) plus Th1 cytokines; dense labeling for IFN-gamma and tumor necrosis factor-alpha, plus lesser amounts of IL-2, was observed.

Defective proliferation and regulatory function of CD4+ T cells bearing Leu-8 homing receptor in primary biliary cirrhosis.
|
552 |

The majority of circulating CD4+ T cells express the Leu-8 peripheral lymph node homing receptor, and these cells have previously been shown to have suppressor-inducer and suppressor function.
|
553 |
7515343

Higher autoantibody levels and recognition of a linear NH2-terminal epitope in the autoantigen GAD65, distinguish stiff-man syndrome from insulin-dependent diabetes mellitus.
|
588 |
7519242
|
Thus, destruction of pancreatic beta cells, which results in insulin-dependent diabetes mellitus (IDDM), and impairment of GABA-ergic synaptic transmission in Stiff-Man syndrome (SMS) are both characterized by circulating autoantibodies to GAD65.
|
589 |
7519242
|
Here we report the characterization of humoral autoimmune responses to GAD65 in 35 SMS patients, of whom 13 (37%) also had IDDM.
|
590 |
7519242
|
All SMS patients immunoprecipitated native GAD65 and the main titers were orders of magnitude higher than in IDDM patients.
|
591 |
7519242
|
Furthermore, in contrast to the situation in IDDM, autoantibodies in 35 of 35 (100%) of SMS patients recognized denatured GAD65 on Western blots.
|
592 |
7519242
|
The first pattern, detected in 25 of 35 SMS patients (71%), of whom 11 had IDDM (44%), was predominantly reactive with a linear NH2-terminal epitope residing in the first eight amino acids of GAD65.
|
593 |
7519242
|
The second epitope pattern may represent epitope spreading in the GAD65 molecule, but may also include some cases of epitope recognition associated with IDDM resistant HLA-haplotypes.
|
594 |
7519242
|
The principal NH2-terminal linear epitope in GAD65 distinguishes the reactivity of SMS and IDDM autoantibodies and may be a determinant of pathogenicity for GABA-ergic neurons.
|
595 |
7519242
|
The greater magnitude and distinct specificity of the humoral response to GAD65 in SMS may reflect a biased involvement of the T helper cell type 2 (Th2) subset of CD4+ T cells and antibody responses, whereas IDDM is likely mediated by the Th1 subset of CD4+ T cells and cytotoxic T cell responses.

Reduced numbers of CD8+ T cells and B cell-expression of Leu-8 antigen in peripheral blood of patients with primary biliary cirrhosis.
|
597 |
7525431
|
In PBC the proportion of PBMC that were CD4+ was normal; in contrast, the proportion that were CD8+ was decreased (p < 0.01).
|
598 |
7525431
|
These findings suggest that in peripheral blood of PBC patients reduced numbers of T cells may occur due to a selective intrahepatic sequestration of CD8+ T cells, and that the decreased expression of Leu-8 antigen by B cells may be associated with their participation in autoimmune processes.

A CD8+ T-lymphocyte-mediated and CD4+ T-lymphocyte-independent autoimmune diabetes of early onset in transgenic mice.

7534735
|
While transgenic mice expressing tumour necrosis factor-alpha under the control of the beta-cell-specific insulin promoter display a marked lymphocytic infiltration of the islets, they never develop insulin-dependent diabetes mellitus (IDDM).
|
601 |
7534735
|
These results indicate that while tumour necrosis factor-alpha induced lymphocytic infiltration is not sufficient to effect beta-cell destruction, locally co-stimulated islet-infiltrating CD8+ T lymphocytes could play a critical role in the development of IDDM.
|
602 |
7540575
|
Transgenic mice that express mouse B7-1 (mB7-1, recently designated CD80) on their pancreatic beta-cells maintain normal islet architecture, have normal pancreatic insulin content, and only rarely spontaneously develop insulitis and diabetes.
|
603 |
7540575
|
While this insulitis resolved in the nontransgenic mice, the islet-infiltrating CD4+ and CD8+ T-cells in the transgenic mice were associated with complete beta-cell destruction.
|
604 |
7545875
|
Autorecognition of many self-proteins by CD4+ T lymphocytes is restricted by the products of class II immune response genes of the major histocompatibility complex (MHC), and in human type I diabetes such a MHC association has been described.

The present study uses a rat MHC class II (RT1.Bl) peptide binding motif to predict potentially autoreactive CD4+ T cell epitopes in two key islet beta-cell constituents: the enzyme glutamic acid decarboxylase (GAD) and the insulin precursor hormone proinsulin (PI).
|
606 |
7545875
|
Seventeen-amino-acid-long peptide fragments of GAD and PI containing the binding motif were synthesized and used to generate peptide-specific, MHC class II-restricted, CD4+ T cell lines.
|
607 |
7545875
|
Once established, the T cell lines specific for rat islet GAD and PI were adoptively transferred to naive, MHC-compatible rats.
|
608 |

Autorecognition of many self-proteins by CD4+ T lymphocytes is restricted by the products of class II immune response genes of the major histocompatibility complex (MHC), and in human type I diabetes such a MHC association has been described.

Increased and decreased relative risk for non-insulin-dependent diabetes mellitus conferred by HLA class II and by CD4 alleles.
|
617 |
7554346

In this study the association of HLA class II alleles and genotypes and the association of CD4 and CD3 polymorphisms were assessed in a large number of Belgian non-insulin-dependent diabetes mellitus patients.
|
618 |
7554346

These results therefore suggest that HLA class II and CD4 genes might independently contribute to the susceptibility for non-insulin-dependent diabetes mellitus and that these alleles and genotypes might identify subgroups of patients with different susceptibilities.

In parallel studies, normal Swiss male mice given stz at a similar dose developed diabetes (10/10) associated with insulitis which consisted predominantly of CD4, CD8 and MAC-1 cells.
|
626 |
7578887
|
The percentage of CD4+PBL was higher in NOD/Smrf females than males, was intermediate in [NOD X NON] F1 mice and approximated a 1:1 distribution in F1 mice backcrossed to either NOD or NON parental strains, suggesting primary control of the phenotype by an incompletely dominant gene, but not excluding additional effects by other genes.
|
627 |
7578887
|
We term this primary gene Tlf(T lymphocyte frequency) because it also influenced the percentage of CD8+ T cells, although to lesser extent and independently from the MHC previously shown to lower the CD8+ T cell fraction in NON mice.
|
628 |
7578887
|
Dihydrotestosterone simultaneously lowered CD4+ PBL levels and prevented diabetes in NOD females while, in vitro, it had a differential effect on Con A elicited cytokines, increasing IL-2 22% and decreasing IL-4 39% (p < 0.0001).

This study was undertaken to determine whether this reduced lymphocyte proliferation is mediated by a decreased production of cytokine or decreased expression of interleukin-2 receptor (IL-2R).
|
635 |
7587921
|
However, the production of IL-1 beta, IL-2 and interferon-gamma, the percentages of pan T cells (CD3), T helper cells (CD4), T suppressor cells (CD8), the ratio of CD4/CD8 and the expression of CR1 and Fc receptors for immunoglobulin G (Fc gamma RII and Fc gamma RIII) were not significantly different between NIDDM patients and healthy subjects.
|
636 |
7587921
|
These findings suggest that decreased expression of CR3 on monocytes, decreased lymphocyte proliferation and decreased IL-2R expression despite a higher production of TNF-alpha may explain the impaired cell-mediated immunity seen in NIDDM patients.

|
Two- and three-color cytofluorimetric techniques were used to study the expression patterns of the activation antigen HLA-DR on peripheral blood immunoregulatory T-cells from 25 patients with newly diagnosed insulin-dependent diabetes mellitus (IDDM) and 14 age- and sex-matched control subjects.
|
640 |
7589848
|
In control subjects, basal activation of CD4+ and CD8+ lymphocytes accounted for the low percentage levels of activated T-cells.
|
641 |
7589848
|
In contrast, the majority of IDDM patients showed an unbalanced activation of CD4+ and CD8+ lymphocytes with predominant activation of the CD8+ lymphocyte subset.
|
642 |
7589848
|
The composition of the activated T-cell fraction was dependent on the composition of the total (activated + nonactivated) T-cell population, as indicated by the positive correlation between the CD4+/CD8+ T-cell ratios in these two cell populations (r = 0.714; P < 0.001).
|
643 |
7589848

Low bcl-2 expression and increased spontaneous apoptosis in T-lymphocytes from newly-diagnosed IDDM patients.
|
667 |
7589882
|
No data exist regarding bcl-2 expression in autoimmune diseases, such as human insulin-dependent diabetes mellitus (IDDM).
|
668 |
7589882
|
We investigated bcl-2 protein expression by testing T lymphocytes from 15 newly-diagnosed (< 3 weeks) IDDM patients in comparison to 10 age-matched control subjects.
|
669 |
7589882
|
When the percentage and mean fluorescence intensity (MFI) of bcl-2+/CD3+ cells from normal individuals and patients were compared, we found that bcl-2 expression within the CD3+ and CD4+ CD45R0+ T-cell populations was reduced significantly in IDDM patients (46.8 +/- 15.4 vs 79.6 +/- 11.7; 25.7 +/- 3.8 vs 47.15 +/- 5.7, respectively; p < 0.001).
|
670 |
7589882
|
Our study suggests that recent onset IDDM is characterised by reduced bcl-2 expression, which in turn may be associated with the increased spontaneous apoptosis we observed.

After transplantation we evaluated simultaneously the level of metabolic control through HbA1c values determined by chromatography, the capacity of insulin secretion through the C-peptide levels (determined by radioimmunoassay) before and 6 minutes after 1 mg glucagon i.v. stimulation, and the ratio between CD4+ and CD8+ lymphocytes determined by immunofluorescence using monoclonal antibodies.

However, the loss of islet function was preceded by the increase in CD4+/CD8+ ratio, thus reflecting the presumable accumulation of CD4+ inducer T-lymphocytes.
|
674 |

When the islet secretion capacity was destroyed, we found a decrease in CD4+/CD8+ ratio, reflecting the recruitment of CD8+ effector cells.

Intrathymic transplantation of islet antigen affects CD8+ diabetogenic T-cells resulting in tolerance to autoimmune IDDM.
|
700 |
7621990
|
Normally, islet antigens that are involved in insulin-dependent diabetes mellitus (IDDM) are not present in the thymus, but we have previously shown that transplantation of islets expressing relevant antigens into the thymus at the time of T-cell maturation results in prevention of IDDM in the multidose streptozotocin model of diabetes mellitus (MDSDM).
|
701 |

Although both CD4+ and CD8+ T-cells are involved in the pathogenesis of this disease, the cells affected by intrathymic transplantation of islets are unknown.

Markers of cell-mediated immune activation were studied in 32 Chinese patients with recent-onset insulin-dependent diabetes mellitus (IDDM) as compared with 12 patients with recent-onset non-insulin-dependent diabetes mellitus (NIDDM) and 34 normal subjects.

|
Sera were assessed for soluble markers of T-cell activation (sCD4, sCD8, sIL-2R); the cytokines (IL-1 beta, TNF-alpha, IL-2, IL-6), and T-cell subsets were also determined.
|
709 |
7647584
|
Three IDDM patients had detectable IL-1 beta and this weakly so (< 3.5 pg/ml).
|
710 |
7647584
|
However, the other cytokine data and the frequency of activated T-cells, CD4+, CD8+ T-cell subsets and CD4:CD8 ratio showed no significant differences among the IDDM, NIDDM and normal subjects.
|
711 |

|
The uniform finding is that T cells are made hyporesponsive, and that the most likely mechanism is one of active suppression mediated through the selective activation of T cells, of either CD4+ or CD8+ phenotype, that make cytokines which in turn can suppress pathological T cells responsible for the disease lesions.

Distinct patterns of inflammation in TNF-alpha and TNF-beta transgenic mice.
|
713 |
7682590
|
To understand the role of TNF in the regulation of inflammation and the development of autoimmune diseases such as insulin-dependent diabetes mellitus, we produced transgenic mice in which the synthesis of murine TNF-alpha was directed by the rat insulin II promoter.
|
714 |
7682590
|
The expression of the TNF-alpha transgene was restricted to the pancreas, in contrast to TNF-beta expression from the same promoter, in which the transgene was expressed in the pancreas, kidney, and skin.
|
715 |
7682590
|
The expression of TNF-alpha in the pancreas of transgenic mice resulted in an overwhelming insulitis, composed of CD4+ and CD8+ T cells and B220+ B cells, considerably greater than that of TNF-beta transgenics.
|
716 |
7682590
|
Moreover, in contrast to the predominant peri-insulitis observed in TNF-beta transgenic mice, the majority of the infiltrate in the TNF-alpha transgenic mice was within the islet itself.
|
717 |
7682590
|
Both TNF-alpha and TNF-beta transgenic mice show elevated expression of leukocyte adhesion molecules VCAM-1 and ICAM-1 in islet endothelia and increased expression of MHC class I on islet cells.

The monoclonal antibodies 2H4 and 4B4 are specifically directed against CD45RA and CD29 antigens, respectively, which are expressed on both CD4+ and CD8+ lymphocytes.
|
720 |
7684344
|
CD45RA and CD29 are expressed on distinct subsets of CD4+ T-cells, whereas in both healthy subjects and IDDM patients, 2H4 and 4B4 labeling does not always differentiate two distinct CD8+ populations.

|
In this context, we have measured the proliferative responses of peripheral blood mononuclear cells (PBMC) to the synthetic peptides corresponding to the extracellular domain of the TSH receptor (TSHR) and recombinant glutamate decarboxylase (GAD65) by means of 3H thymidine incorporation.
|
772 |
7714099

We have also studied the antigenic activation of CD4+ and CD8+ T lymphocytes by measuring human leukocyte antigen-DR (HLA-DR) expression on the cell surface by flow cytometric analysis.
|
773 |
7714099
|
PBMC obtained from 47 patients with Graves' disease (GD) [including 19 hyperthyroid GD (hyper GD)], 18 with Hashimoto's thyroiditis (HT), 7 with nontoxic nodular goiter (NG), 18 with insulin-dependent diabetes (IDDM), and 20 normal controls (N), were cultured for 7 days in the presence or absence of the pool peptides representing 3 different segments of TSHR or GAD65 at final concentration of 30 micrograms/mL or 10 micrograms/mL.
|
774 |
7714099
|
The proportion of subjects whose PBMC gave a positive proliferative response with a stimulation index (SI) of over 2.3 (i.e. above the mean +2 SD for N) to TSHR peptides was significantly higher in the hyper GD group than among euthyroid GD (eu GD), HT, IDDM, and N group.
|
775 |
7714099
|
The CD4+ T lymphocytes from hyper GD group were significantly more activated by TSHR peptides compared to eu GD, HT, IDDM, and N, and this induction correlated to their thyroid hormone levels.
|
776 |
7714099
|
Quite differently, the activation of CD8+ T lymphocytes from both hyper GD and eu GD group in response to TSHR peptides was impaired compared to HT, IDDM, and the N group; in contrast to the findings with CD4+ T lymphocytes, this was independent of thyroid hormone levels.
|
777 |

The time required to transfer insulin-dependent diabetes mellitus (IDDM) using islet-infiltrating lymphocytes from young prediabetic mice (25 +/- 9 days) was not statistically different from the time required to transfer IDDM using splenocytes from overtly diabetic mice (32 +/- 5 days).
|
807 |
7729614
|
Cotransfer of splenocyte cells or CD4+, but not CD8+ spleen cells, from 60- to 80-day-old prediabetic female NOD mice together with either splenocytes from diabetic mice or islet-infiltrating lymphocytes from prediabetic NOD mice delayed the rapid transfer of IDDM, suggesting that CD4+ cells mediated immunoregulation.

815 |
7813805
|
We followed, by in situ hybridization, the appearance of mRNA of the tumor necrosis factor (TNF)-alpha gene and, as a marker for activated cytotoxic T-cells, of the serine protease granzyme A gene in the cellular infiltrates generated by cell transfer at birth.
|
816 |

Polymorphisms in HLA class II genes have been shown to contribute to susceptibility or protection against insulin-dependent diabetes mellitus (IDDM).
|
831 |
7834277
|
In the present study the role of HLA class II haplotypes and the role of DQ alpha Arg52, DQ beta Asp57 and of polymorphic amino acids, located in the antigen-binding groove and the CD4-binding domain of the DR beta 1 chain, were studied in 210 unrelated Caucasian IDDM patients and 205 controls.
|
832 |

T cells play a major role in the development of insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice.
|
840 |
7836934
|
Administration of interleukin 12 (IL-12), a key cytokine which guides the development of T helper type 1 (Th1) CD4+ T cells, induces rapid onset of IDDM in NOD, but not in BALB/c mice.
|
841 |
7836934
|
CD4+ pancreas-infiltrating T cells, after activation by insolubilized anti T cell receptor antibody, secrete high levels of interferon gamma and low levels of IL-4.
|
842 |

|
When T cell subsets from insulin-fed animals were co-injected with diabetogenic T cells, only purified CD4+ T cells were able to transfer protection since only 3/12 mice became diabetic after 36 days in comparison to 3/6 in the group co-injected with CD4+ T cells from PBS-fed animals, or 5/6 in the group injected with CD8+ T cells.

The participation of IL-2 in insulin-dependent (type 1) diabetes (IDDM) was analyzed in transgenic (tg) mice expressing the nucleoprotein (NP) of lymphocytic choriomeningitis virus and IL-2 under control of the rat insulin promoter focally in beta cells of the islets of Langerhans.
|
848 |
7860729
|
Insertion and expression of the viral (self) gene or of the IL-2 gene alone did not lead to IDDM.
|
849 |
7860729
|
Infiltration primarily of CD4 and B lymphocytes and increased expression of MHC class I and II molecules occurred in islets where IL-2 was expressed.
|
850 |
7860729
|
In contrast, viral inoculum to single tg mice expressing either the viral protein or IL-2 failed to enhance the incidence of IDDM over 30% for viral protein or 10% for IL-2 after an 8-mo observation period.

Insulin immunization of nonobese diabetic mice induces a protective insulitis characterized by diminished intraislet interferon-gamma transcription.
|
852 |
7860747
|
Adoptive transfer of splenocytes from B-chain insulin-immunized mice prevented diabetes in recipients co-infused with diabetogenic spleen cells, an effect that was abolished by prior in vivo elimination of either CD4+ or CD8+ cells.
|
853 |
7860747
|
Insulin immunization did not reduce the extent of intraislet inflammation (insulitis); however, it did abolish expression of IFN-gamma mRNA within the insulitis lesions.
|
854 |
7865456
|
To examine the role of IL-2 in the regulation of peripheral tolerance we produced transgenic mice in which the expression of murine IL-2 was directed by the rat insulin II promoter.

Insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice results from a cell-mediated autoimmune process against pancreatic beta-cells.
|
858 |
7868915
|
We have shown that beta-cell-cytotoxic CD8+ T cell clones can transfer IDDM to irradiated NOD mice if co-injected with nondiabetogenic CD4+ spleen T cells.
|
859 |
7868915
|
To determine whether CTLs recruited to pancreatic islets recognize a restricted set of local Ags, we sequenced TCR-alpha and TCR-beta cDNA generated by anchor PCR from CD8+ CTL lines and clones derived from islets of 10 different NOD mice.
|
860 |
7868915
|
By contrast, none of 31 different TCR-alpha rearrangements used by CD8+ spleen T cells encoded motifs 1 or 2, and only one encoded motif 3.
|
861 |
7868915
|
Skewed TCR-alpha-CDR3 usage by islet-derived CTLs was substantiated further by isolation of CTL clones transcribing highly homologous TCR-alpha, but different TCR-beta, rearrangements.

We developed two distinct transgenic mouse models in which virus induced insulin-dependent (type 1) diabetes mellitus (IDDM).
|
875 |
7889411
|
By contrast, induction of an anti-self (anti-viral) CD8+ CTL response to the same virus later in life caused IDDM (incidence < 90%) in both transgenic lines, although the kinetics and requirements for CD4 help, the affinity and avidity of CD8+ CTL differed in each line.

T-cell-T-cell collaboration in allogeneic responses traditionally has been viewed as the requirement for CD4+ T helper cells in the activation of CD8+ cytotoxic T cells.
|
887 |
7902104
|
In this regard, the role of the CD4+ T cell is primarily to provide growth factors, such as interleukin-2, on which the CD8+ T cell is dependent.

The accelerating effect of IL-2 was present; but decreased, in NOD mice that lacked CD8+ T cells as well as in NOD SCID mice.
|
908 |
7925581
|
The implications are that in the NOD genetic background, the production of cytokines, such as IL-2, by islet-specific CD4+ T cells can lead to beta cell damage and diabetes and that CD8+ T cells may have a role in accelerating diabetes onset.

Flow cytometric analysis showed that BNY-2 cells were positive for CD4 and CD5 and were negative for CD8 and RT6, indicating that these cells were phenotypically Th cells rather than cytotoxic T cells. mAbs against rat MHC class II Ags (anti-RT1.D) blocked the proliferation response of BNY-2 cells, suggesting that these cells recognize the MHC class II Du molecule.

On the other hand, IL-4, which is also produced by CD4-positive T lymphocytes, was increased.

More rigorous exclusion of CD8+ cells by means of anti-CD8 MoAb treatment in vivo of the recipients of enriched CD4+ cells demonstrated a significant difference in the diabetogenic potency of CD4+ lymphocytes from diabetic versus nondiabetic donors.
|
970 |
8093606
|
Evidence is discussed indicating that the age-associated differences in ability of CD4+ T-cells to adoptively transfer diabetes in the absence of the CD8+ T-cells subset is a function of prior, chronic exposure of the CD4+ lymphocytes to beta-cell antigens in the donor.

Diabetes in these lymphopoenic rats was associated with extensive insulitis involving CD4+ and CD8+ T cells and macrophages.
|
972 |
8094734
|
The autoimmune diabetes and insulitis were completely prevented by the injection of a particular CD4+ T cell subset, isolated from healthy syngeneic donors, of the phenotype CD45RClow T cell receptor alpha/beta+ RT6+ Thy-1- OX-40-.
|
973 |
8094734

Cells of this protective phenotype, which make up about 5% of thoracic duct lymphocytes, were found to provide help for secondary antibody responses and produce interleukin 2 (IL-2) and IL-4, but no interferon gamma, on in vitro activation.

This population, composed of CD4+ and CD8+ T cells, is presumably committed against the relevant beta cell antigens and is the most likely to reveal a bias in V gene usage if such a bias does indeed exist.
|
978 |
8095459
|
In contrast, the depletion of V beta 6-positive T cells results in a severe reduction of transfers, suggesting that V beta 6 gene is used with a relatively high frequency by diabetogenic CD4+ and/or CD8+ T cells.

A suppressor mechanism involving CD8+ T cells might be involved since in vitro these cells strongly proliferated in response to irradiated CD4+ V beta 8+ T cells that in blocking experiments with specific mAb was found to be class I major histocompatibility complex (MHC)-restricted.
|
982 |
8096128
|
Hence, T cells expressing the CD8 phenotype specifically respond to idiotypic or ergotypic determinants on the inducing activated CD4+V beta 8+ T cells and effectively suppress a diabetogenic disease process by a mechanism that may involve T-T cell interactions.

Administration of morphine significantly inhibited the phorbol myristate acetate (PMA)-stimulated increase in interleukin-2 receptor (IL-2R) expression in both CD4+ and CD8+ mouse T cells.
|
986 |
8098501
|
In contrast, morphine treatment had no effect on PMA/calcium ionophore (A23187)-induced increase in IL-2 secretion, suggesting a selective inhibition of IL-2R expression.
|
987 |
8098501
|
Moreover, adrenalectomy abolished this effect of morphine in CD4+ but not CD8+ T cells, suggesting that the inhibitory effect of morphine on IL-2R expression in CD4+ T cells may be mediated through a morphine-induced increase in corticosteroid levels.

To analyze of the roles of CD4+ and CD8+ T cells in the pathogenesis of this mouse, we have been doing a series of studies on the induction of insulitis and diabetes in NOD athymic nude mice by means of T cell transfer.
|
992 |
8098666
|
On the other hand, transfer of either CD4+ cell-depleted or CD8+ cell-depleted splenic lymphocytes of diabetic mice did not cause diabetes at least up to 60 days after the cell transfer.
|
993 |
8098666
|
However, insulitis was less potent in this group of mice than in the diabetic recipients given both subsets: only a low insulitis score was obtained and a number of beta-cells remained alive despite the insulitis in mice given the CD8+ T cell-depleted fraction, whereas islet damage was very severe and insulin-secreting beta-cells were no longer detected in the diabetic mice.
|
994 |
8098666
|
Consideration of our results together with earlier findings led to the conclusion that CD4+ T cells are primarily responsible for insulitis and that CD8+ T cells migrate into islets and are differentiated into mature killer cells against beta-cells with the aid of CD4+ T cells in both spontaneous and cyclophosphamide-induced diabetes.

Insulin-dependent diabetes mellitus (IDDM) is an autoimmune disease marked by hyperglycemia and mononuclear cell infiltration of insulin-producing beta islet cells.
|
1018 |
8101862
|
Predisposition to IDDM in humans has been linked to the class II major histocompatibility complex (MHC), and islet cells often become aberrantly class II positive during the course of the disease.
|
1019 |
8101862
|
These results suggest that in this model of autoimmune diabetes, CD4+ T cells and MHC class II molecules are not required for the development of disease.
|

Progressive disease was found to be associated with the presence in the serum of IgA, IgE, and IgG1 Candida-reactive specific antibodies, absent footpad reactions, and elevated production in vitro of the Th2 cytokines IL-4, IL-6, and IL-10 but not the Th1 cytokine IFN-gamma.
|
1021 |
8102088
|
Both the Th2 and Th1 (IL-2 and IFN-gamma) cytokines were produced in vitro by CD4+ lymphocytes from noninfected diabetic mice that, in addition, showed a noticeable footpad reaction to Candida antigens.

Results indicate that 1) cytokine mRNA profiles exhibited by islet-infiltrating cells of female and male NOD mice were quite similar with the exception of IL-6 expression and the marked differences in the levels of IL-2 receptor and IL-1 alpha mRNA, 2) CD4+ T lymphocytes expressed IL-4, presumably IL-5, and occasionally IL-10 mRNA but no detectable IL-2 mRNA, 3) CD8+ T lymphocytes exhibited TNF-beta, perforin and high levels of IFN-gamma, and 4) IL-7 was expressed in the islet at very high levels.

Lymphocytes infiltrating salivary glands expressed LFA-1 and Pgp-1 although Mel-14 Ag was absent.
|
1038 |
8207221
|
With regard to peripheral lymphocytes, the proportion of CD4 and CD8 cells expressing Mel-14 was decreased in the infiltrated islets, whereas the expression of LFA-1, Pgp-1, and LPAM-1/2 was increased.
|
1039 |

We examined pancreas biopsy specimens from 18 newly diagnosed insulin-dependent diabetes mellitus (IDDM) patients to elucidate the mechanism underlying beta cell destruction.
|
1045 |
8227346
|
Infiltrating mononuclear cells consisted of CD4+T, CD8+T, B lymphocytes, and macrophages.
|
1046 |
8227346
|
The expression of intercellular adhesion molecule-1 was increased in endothelial cells in two of the nine patients with MHC hyperexpression; in one of them, lymphocyte function-associated antigen-3 expression was also increased.
|
1047 |
8227346
|
In conclusion, we revealed the close relation between CD8+T lymphocyte-predominant insulitis and MHC class I hyperexpression in islet cells.
|
1048 |
8227346
|
This suggests that infiltrating CD8+T lymphocytes recognize islet autoantigens in association with increased MHC class I molecules and act as major effector cells in autoimmune response against islet cells in IDDM pancreases.
|
1049 |
8240789
|
Changes in the plasma concentrations of interleukin-1 beta (IL-1 beta), tumour necrosis factor alpha (TNF alpha), interleukin 2 (IL-2), and lymphocyte subsets were investigated in 19 persons with newly diagnosed (type 1) insulin-dependent diabetes mellitus (IDDM) from admission to hospital prior to insulin treatment and following 1 week and 1 month of treatment.
|
1050 |
8240789
|
The lymphocyte subsets (CD5+, CD8+, CD4+, CD16+, CD20+, HLA-DR+) did not show any significant changes from admission to after the start of insulin treatment.
|
1051 |
8240789
|
It is concluded that the gradual increase in IL-1 beta and TNF alpha plasma levels may reflect an ongoing autoimmune inflammatory reaction at the onset of IDDM.

Resting rat and human T cells bound 125I-AGE-albumin with an affinity of 7.8 x 10(7) M-1, whereas, after stimulation with phytohemagglutinin (PHA) for 48 h, binding affinity increased to 5.8 x 10(8) M-1.
|
1057 |
8245789
|
Flow cytometric analysis of resting rat T cells using polyclonal antibodies raised against rat liver AGE-binding proteins (p60 and p90) revealed the constitutive expression of both immunoreactivities.
|
1058 |
8245789
|
The number of resting CD4+ and CD8+ T cells positive for anti-p60 antibody binding (34.2 and 58.5%, respectively) increased to 92 and 90% of cells after 48-h stimulation with PHA.
|
1059 |
8245789
|
Exposure of PHA-activated T lymphocytes to AGE-albumin enhanced expression of interferon gamma (IFN-gamma) mRNA 10-fold and induced greater elaboration of the mature protein than did exposure to unmodified protein or PHA treatment alone.

The infiltrate contains both CD4+ and CD8+ T cells and both are required for progression to diabetes in non-obese diabetic (NOD) mice.
|
1061 |
8258349
|
It has been thought that the CD4+ lymphocytes are the initiators of the disease, the islet invaders, while CD8+ cells are the effectors, the islet destroyers.
|
1062 |
8258349
|
We question this interpretation because NOD mice lacking MHC class I molecules, hence CD8+ T cells, do not display even insulitis when expected.

In spite of the fact that CD4 plays a critical role in thymocyte development, the abnormal signaling does not appear to influence thymocyte development at the stage when the T-cell receptor is rearranged and the recombinase enzymes RAG-1 and RAG-2 transcripts are downregulated.
|
1069 |
8270129
|
Analyses of T-cell subsets before and after diabetes onset revealed CD4+ T cells as predominant (50-55% of total T cells) with double-negative (CD4-CD8-) T cells (25-30%) and CD8+ T cells (15-20%) also present in significant quantities.
|
1070 |

|
Critical immunological values were established (CD5+ cells--1200 in 1 microliter, CD4+ cells--35%, expression of CD5 and antigens HLA class II--110 and 75%, respectively) for septic complications which are highly probable in lower indices.
|
1071 |
8314024
|
Although it is widely agreed that class II-restricted CD4+ T-cells are essential for the development of diabetes in the NOD model, some studies have suggested that CD8+ T-cells are not required for beta-cell destruction.
|
1072 |
8314024
|
To assess the contribution of CD8+ T-cells to diabetes, we have developed a class of NOD mouse that lacks expression of beta 2-microglobulin (NOD-B2mnull).
|
1073 |
8315397
|
Beginning at the time of insulitis (7 wk of age), CD4+ and CD8+ mature thymocytes from nonobese diabetic (NOD) mice exhibit a proliferative unresponsiveness in vitro after T cell receptor (TCR) crosslinking.
|
1074 |
8315397
|
However, since equivalent levels of IL-3 were secreted by Con A-activated NOD and BALB/c thymocytes, the unresponsiveness of NOD thymic T cells does not appear to be dependent on reduced IL-2 secretion.
|
1075 |
8315397
|
Exogenous recombinant (r)IL-2 only partially reverses NOD thymocyte proliferative unresponsiveness to anti-CD3, and this is mediated by the inability of IL-2 to stimulate a complete IL-4 secretion response.
|
1076 |
8315397
|
In contrast, exogenous IL-4 reverses the unresponsiveness of both NOD thymic and peripheral T cells completely, and this is associated with the complete restoration of an IL-2 secretion response.
|
1077 |
8318452
|
The non-obese diabetic (NOD) mouse spontaneously develops a T cell-mediated autoimmune disease, sharing many features with human insulin-dependent diabetes mellitus (IDDM), leading to insulin-secreting beta cell destruction.

First, CD4+ T cells from diabetic animals are required to transfer diabetes to non-diabetic recipients in conjunction with CD8+ effector T cells.

1096 |
8420810
|
The proportion of CD4 lymphocytes expressing CD45RA alone (CD45RA+RO-) was similar in these groups, but the percentage of CD8 lymphocytes that were CD45RA+RO- was significantly higher in the patients with recent-onset IDDM (P < 0.05).

Numbers of mature TCRhigh/CD4-8+ thymocytes, and also their TCRhigh/CD4+8+ precursors were decreased, as were levels of CD8 expression on all thymocyte subsets investigated.
|
1202 |
8558007

The aging process is associated with a significant reduction in circulating GH and insulin-like growth factor I (IGF-I) levels.
|
1233 |
8603576
|
At the end of the 7-week period, the animals were killed. rhGH and rhIGF-I increased serum GH and IGF-I levels, respectively; rhGH and rhIGF-I in combination induced the highest serum IGF-I levels (906 +/- 261 ng/ml vs. control, 185 +/- 36 ng/ml at death). rhGH and rhIGF-I also increased IGFBP-3 levels. rhGH infusion resulted in the most marked changes in lymph node and splenic reactivity, as determined by histological assessment.
|
1234 |
8603576
|
In the peripheral blood, the percent B cells and percent CD8 cell count rose after rhIGF-I therapy, with a fall in the CD4/CD8 ratio.

In addition, adoptive transfer of LCMV-GP-specific TCR transgenic perforin-deficient T cells activated by LCMV-GP recombinant vaccinia virus led to marked insulitis with infiltration of CD4+ and CD8+ T cells without the development of diabetes.

|
Nasal administration of glutamate decarboxylase (GAD65) peptides induces Th2 responses and prevents murine insulin-dependent diabetes.
|
1253 |
8666914
|
Induction of passive tolerance to GAD65, through inactivation of reactive T cells before the onset of autoimmunity, prevented determinant spreading and the development of insulin-dependent diabetes mellitus (IDDM).
|
1254 |
8666914
|
Here, we examined whether an alternative strategy, designed to induce active tolerance via the engagement of Th2 immune responses to GAD65, before the spontaneous onset of autoimmunity, could inhibit the cascade of Th1 responses that lead to IDDM.
|
1255 |
8666914
|
GAD65 peptide treated mice displayed greatly reduced IFN gamma responses and increased IL-5 responses to GAD65, confirming the diversion of the spontaneous GAD65 Th1 response toward a Th2 phenotype.
|
1256 |
8666914
|
Consistent with the induction of an active tolerance mechanism, splenic CD4+ (but not CD8+) T cells from GAD65 peptide-treated mice, inhibited the adoptive transfer of IDDM to NOD-scid/scid mice.
|
1257 |
8666914
|
Finally, GAD65 peptide treatment reduced insulitis and long-term IDDM incidence.

In all of the H-2d islet-grafted (NOD x BALB/c) F1 mice that received the beta-CTL clones, the beta-CTLs homed into the grafts, recruited host Mac-1+ cells and CD4+ and CD8+ T-cells, and caused diabetes within 7 days.
|
1259 |
8690161
|
We conclude that (1) islet-derived beta-CTLs can destroy beta-cells in vivo; (2) infiltration of grafted islets by beta-CTLs is an MHC class I-restricted response; (3) beta-CTLs can recruit naive CD4+ T-cells to the site, leading to further beta-cell damage; and (4) revascularized islet grafts are, like pancreatic islets of irradiated adult NOD mice, "sequestered" from circulating beta-CTLs.

According to immunocytochemical analysis, the pancreatic inflammatory infiltrates of streptozotocin-injected transgenic mice contained CD4+ and CD8+ T lymphocytes, B lymphocytes and macrophages.
|
1266 |
8738973
|
We now report that cyclophosphamide constitutes an apoptosis signal to peripheral lymphocytes and we provide evidence that NOD B cells as well as both CD4 and CD8 T cells display resistance to cyclophosphamide-induced apoptosis.
|
1267 |
8740409
|
Immunophenotyping of the inflammatory infiltrate with rat lymphocyte-specific markers showed CD45-, CD8-, and CD4-positive cells.
|
1268 |
8746558
|
Likewise, the NOD-derived NIT-1 beta cell line did not express surface B7 or B7-1 mRNA either constitutively or following exposure to IFN-gamma and TNF-alpha, two cytokines known to be present in the insulitis lesion of NOD mice, or cAMP which can induce B7-1 expression on B cells.
|
1269 |
8746558
|
By immunohistochemistry and flow cytometry, it was determined that the phenotype of B7+ cells in the pancreas of NOD mice 9 days after cyclophosphamide included a mixture of macrophages and both CD4+ and CD8+ T cells.
|
1270 |
8746558
|
RIP-IL-2 transgenic mice, which have extensive islet infiltration but no autoimmune beta cell destruction, also had virtually no B7-1 expression and a minority of B7-2-expressing inflammatory cells.

IFN-alpha induces autoimmune T cells through the induction of intracellular adhesion molecule-1 and B7.2.
|
1292 |
8752897
|
We demonstrate that the expression of IFN-alpha by the pancreatic beta cells leads to the development of CD4+ T cells that proliferate in the presence of islet Ags.
|
1293 |
8752897
|
We also demonstrate that the pancreatic infiltrating leukocytes in the transgenic mice express increased levels of 87.2 and ICAM-1 and that IFN-alpha can directly induce these two costimulatory molecules on nontransgenic splenic APCs.
|
1294 |
8752897
|
Treatment of the transgenic mice with Abs against these costimulatory molecules demonstrated that B7.2 is essential for the induction of autoreactive T cells, whereas ICAM-1 contributes to but is not essential for the formation of these autoreactive cells.
|
1295 |
8752897
|
As B7.2 and ICAM-1 are able to synergize to provide costimulatory signals to naive T cells under conditions of limiting Ag, we propose that IFN-alpha expression normally contributes to the development of an anti-viral cellular immune response, but that uncontrolled expression of this cytokine will induce autoimmunity.

The CD4 determinant for downregulation by HIV-1 Nef directly binds to Nef.

Using heteronuclear NMR spectroscopy, we demonstrate that a 13-residue peptide (MS-QIKRLLSEKKT) from the cytoplasmic tail of CD4 binds to Nef protein.

When Nef is complexed to the SH3 domain of Hck tyrosine protein kinase, the peptide binds to the same site on Nef but with slightly higher affinity (Kd approximately 0.5 mM).

This indicates that the binding of CD4 and Hck SH3 to Nef are two compatible and slightly cooperative events.

This indicates that the binding of CD4 and Hck SH3 to Nef are two compatible and slightly cooperative events.

The CD4 determinant for downregulation by HIV-1 Nef directly binds to Nef.
|
1312 |

|
Using heteronuclear NMR spectroscopy, we demonstrate that a 13-residue peptide (MS-QIKRLLSEKKT) from the cytoplasmic tail of CD4 binds to Nef protein.

This part of CD4 is critical for downregulation of CD4 by HIV-1 Nef [Aiken et al. (1994) Cell 76, 853-864].
|
1314 |

|
When Nef is complexed to the SH3 domain of Hck tyrosine protein kinase, the peptide binds to the same site on Nef but with slightly higher affinity (Kd approximately 0.5 mM).

The role of CD8+ T cells in the initiation of insulin-dependent diabetes mellitus.
|
1317 |
8765018
|
While it is generally accepted that T cells are critical for the development of diabetes in the non-obese diabetic (NOD) mouse, the precise functions of the CD4+ and CD8+ subsets remain ill-defined.
|
1318 |
8765018
|
Transfer experiments have provided evidence that CD4+ cells are the disease initiators, provoking massive mononuclear leukocyte infiltration into the pancreatic islets, while CD8+ cells play an effector role, responsible for the final destruction of islet beta cells.
|
1319 |
8765018
|
It was surprising, then, to find that NOD mice carrying a null mutation at the beta 2-microglobulin (beta 2-mu) locus, and thereby lacking major histocompatibility complex class I molecules and CD8+ T cells, developed neither insulitis nor diabetes.
|
1320 |
8765018
|
Transfer experiments indicate that the lack of CD8+ cells during this period somehow alters the phenotype of CD4+ cells, preventing them from expressing their insulitis potential.
|
1321 |
8765018
|
Given that neither the beta 2-mu mutation nor anti-CD8 treatment affect insulitis in a T cell receptor transgenic (tg) mouse strain with a CD4+ T cell repertoire highly skewed for an anti-islet cell reactivity, the most straight-forward interpretation of these observations is that CD8+ cells are required for effective priming and expansion of autoreactive CD4+ cells.

Twenty-four patients with moderately controlled insulin dependent diabetes with a duration of diabetes ranging from 2 to 10 years as well as 17 control subjects were vaccinated against hepatitis B virus using Gen Hevac B vaccine.
|
1341 |

In diabetic patients the most striking feature was the reduced CD4/CD8 ratio which was significantly lower (P < 0.001) than that of the control group.

Defective expression of the apoptosis-inducing CD95 (Fas/APO-1) molecule on T and B cells in IDDM.
|
1343 |
8786019
|
To determine whether a defect involving the CD95 receptor is associated with human insulin-dependent diabetes mellitus (IDDM), we have studied the expression of CD95 on peripheral blood mononuclear cells from IDDM patients at different stages of the disease.
|
1344 |
8786019
|
Three-colour flow cytometry and mean fluorescence analysis showed that T and B lymphocytes from newly diagnosed IDDM and patients with long-standing disease, and subjects at high risk of developing the disease were highly defective in CD95 expression (p < 0.001), whereas monocytes from all the groups studied expressed normal amounts of CD95 molecules on their cell surface.
|
1345 |
8786019
|
T-cell subset analysis showed that the impairment of CD95 expression in IDDM patients and high-risk subjects involved both CD3+ CD4+ (p < 0.001) and CD3+ CD8+ cells (p range: < 0.01-0.001), suggesting that this alteration concerns both helper and cytotoxic T cells.
|
1346 |
8786019
|
Moreover, after activation in vitro with anti-CD3 monoclonal antibody, T cells from newly diagnosed IDDM patients maintained a reduced CD95 expression during the entire cell culture period (24-72 h) in comparison to the control population (p < 0.001).
|
1347 |
8786019
|
In conclusion, we found a reduced expression of the apoptosis-inducing CD95 receptor on T and B lymphocytes of individuals with clinical and preclinical IDDM.

Insulin-dependent diabetes mellitus (IDDM) in the non-obese diabetic (NOD) mouse results from effector T cell-mediated autoimmune processes directed against pancreatic beta cells.

|
The clone was found to produce substantial amounts of transforming growth factor beta (TGF-beta), IL-10, and IFN-gamma, but not IL-2 or IL-4, indicating that this T cell clone is not a member of either the classic Th1 or Th2 cell type.
|
1350 |
8816968
|
On the basis of these observations, we suggest that a new type of CD4+ suppressor T cell, NY4.2, by secreting TGF-beta, can prevent effector T cell-mediated beta cell destruction.

Derived from NOD mice, diabetogenic T-cell lines and clones have for the most part been CD4+ and T-helper 1 (Th1)-like in their cytokine production.

Some CD8+ cytotoxic clones have also been reported, although these have generally not transferred diabetes in the absence of CD4+ T-cells.
|
1353 |

While many of the T-cell lines and clones described react with islets, isolated islet cells, or islet membrane preparations, others have known antigen specificities, reacting with defined islet cell proteins such as insulin, GAD, and heat shock proteins.

Both CD4+ and CD8+ T-cells in syngeneic islet grafts in NOD mice produce interferon-gamma during beta-cell destruction.

|
Islet grafts from CFA-injected mice contained fewer CD4+ and CD8+ cells and more B cells; also fewer interferon gamma (IFN-gamma), interleukin-2 (IL-2), and tumor necrosis factor alpha (TNF-alpha)-positive cells and more IL-4 and IL-10 positive cells.
|
1359 |
8826970
|
By performing two-color immunostaining of cell surface antigens and intracellular IFN-gamma, we found that IFN-gamma positive cells in islet grafts from CFA- and PBS-injected mice were approximately equally divided between CD4+ and CD8+ T-cell subsets.
|
1360 |
8826970
|
Also, the frequencies of both CD4+ IFN-gamma + and CD8+ IFN-gamma + cells were decreased in islet grafts from CFA-injected mice.
|
1361 |

These findings suggest that destruction of beta-cells in syngeneic islets transplanted into NOD mice is promoted by cells producing Th1-type cytokines (IFN-gamma, IL-2, and TNF-alpha) and prevented by cells producing TH2-type cytokines (IL-4 and IL-10).
|

Expression of a beta2m transgene controlled by the rat insulin promoter (RIP-beta2m) in NODbeta2mnull mice resulted in reconstitution of IFN-gamma-inducible cell surface MHC class I protein on pancreatic beta-cells.
|
1391 |

These studies demonstrate that beta2m and cell surface MHC class I expression on beta-cells are essential for the initiation of diabetes in the NOD mouse and further confirm that efficient progression to diabetes requires both CD4+ and CD8+ T cells.

These findings clearly demonstrate (1) a critical role for CD8 T cells in the acute rejection of pancreatic islet tissue allografts and (2) tissue-specific differences in the participation of CD4 T cells as primary effectors in the rejection reaction.
|
1409 |
8889212

Thus, the participation of CD8 and CD4 T cells as primary effectors of graft rejection depends on which class or classes of MHC antigens are constitutively expressed on graft parenchymal cells and are available for recognition.

Expression of the V(beta)8.1+ TCR-beta rearrangement of a diabetogenic H-2Kd-restricted beta cell cytotoxic CD8+ T cell (beta-CTL) clone in NOD mice caused a 10-fold increase in the peripheral precursor frequency of beta-CTL and a selective acceleration of the recruitment of CD8+ T cells to the pancreatic islets of prediabetic animals.
|
1415 |
8906855
|
Most islet-derived beta-CTL from diabetic transgenic NOD mice expressed an endogenously-derived TCR-alpha sequence identical to that of the clonotype donating the TCR-beta transgene, and a TCR-alpha-CDR3 sequence homologous to those expressed by most islet-derived beta-CTL from nontransgenic NOD mice.
|
1416 |

TCR-beta transgene expression did not change the peripheral frequency of beta cell-specific CD4+ T cells, the rate at which these cells accumulated in the pancreatic islets, or the incidence of diabetes.
|
1417 |
8906855
|
Taken together, our data indicate that retention of CD8+ and CD4+ T cells in the pancreatic islets of NOD mice is driven by beta cell autoantigens, rather than by local superantigens or non-Ag-specific stimuli, and that beta-CTL are major effectors of beta cell damage in spontaneous insulin-dependent diabetes mellitus.

TCR-beta transgene expression did not change the peripheral frequency of beta cell-specific CD4+ T cells, the rate at which these cells accumulated in the pancreatic islets, or the incidence of diabetes.
|
1423 |
8906855
|
Taken together, our data indicate that retention of CD8+ and CD4+ T cells in the pancreatic islets of NOD mice is driven by beta cell autoantigens, rather than by local superantigens or non-Ag-specific stimuli, and that beta-CTL are major effectors of beta cell damage in spontaneous insulin-dependent diabetes mellitus.

The expression of class II MHC antigens by allogeneically activated thymocytes demonstrated a novel heterogeneity amongst mature CD4+ CD8- thymocytes that could not readily be accounted for in terms of differences in maturity of the cells, in the affinity of the TCR for the stimulating ligands or in the stage in the cell cycle.

To analyze the effects of TNF alpha in insulin-dependent diabetes mellitus (IDDM), we have generated nonobese diabetic (NOD) transgenic mice expressing TNF alpha under the control of the rat insulin II promoter (RIP).
|
1429 |
8920883
|
In transgenic mice, TNF alpha expression on the islets resulted in massive insulitis, composed of CD4+ T cells, CD8+ T cells, and B cells.
|
1430 |
8920883
|
Despite infiltration of considerable number of lymphoid cells in islets, expression of TNF alpha protected NOD mice from IDDM.
|
1431 |
8920883
|
Diabetes was induced however, in the RIP-TNF alpha transgenic mice when CD8+ diabetogenic cloned T cells or splenic cells from diabetic NOD mice were adoptively transferred to these mice.

CD4+CD8- thymocytes that express L-selectin protect rats from diabetes upon adoptive transfer.

Further studies have demonstrated that the transfer of CD4+CD8- thymocytes, like that of unfractionated CD4+ peripheral T cells, also protects approximately half of recipients from diabetes suggesting that, as with the peripheral T cells, a functional heterogeneity may exist amongst CD4+CD8- thymocytes.
|
1434 |
8921958

In this study, we show that L-selectin is expressed by 50-60% of all CD4+CD8- thymocytes from 6-week-old rats.
|
1435 |
8921958
|
Adoptive transfer of these populations into thymectomized and irradiated rats revealed that the protection from diabetes observed by CD4+CD8- thymocytes was mediated almost entirely by the L-selectin+ subset.
|
1436 |
8921958

We tested whether aminoguanidine (AG), a competitive inhibitor of inducible nitric oxide synthase, might block beta cell destruction and prevent insulin-dependent diabetes mellitus in vivo.
|
1458 |
8930185
|
In terms of therapy, life-table analysis indicated the frequency of insulin-dependent diabetes mellitus (6/30 AG-treated vs. 11/31 vehicle-treated, P = .25) and insulitis scores (2.0 +/- 1.1 vs. 2.4 +/- 1.2 in nondiabetic AG- and vehicle-treated mice at 32 wk, respectively, P = .20) were similar in both groups.
|
1459 |

Flow cytometric analysis revealed no quantitative differences in islet infiltrating macrophages, CD4+ or CD8+ T lymphocytes between groups of animals randomly killed at 8, 16 and 32 wk.

Commonly observed features of these mice include organized lymphocytic foci, composed of CD4+ and CD8+ T-cells, in both the salivary and the lacrimal glands.

Abnormalities in postthymic T cell development in the BB/W rat model of autoimmune insulin-dependent diabetes mellitus (IDDM) result in part from a lymphopenia (lyp) gene defect.

|
These results suggested that, at a minimum, an arrest in maturation of the Thy1+ precursors of RT6+ T cells occurs postthymically in DP rats.
|
1463 |
8937686
|
The results showed that in DP, as compared with DR, rats: 1) 5-fold fewer RTE's are exported from the thymus per 24 hr; 2) more than 80% of the RTE's are CD4+; 3) most of the immediate descendants of RTE's disappear from the peripheral lymphoid tissues within one week after export from the thymus; and 4) few of the descendants of the RTE's that do survive differentiate into RT6+ T cells.

IL-7 reverses NK1+ T cell-defective IL-4 production in the non-obese diabetic mouse.
|
1465 |
8943570
|
We recently reported that IL-7 preferentially promotes the in vitro expansion of a discrete MHC class I-dependent lymphocyte subset comprising both CD4+ and CD4-CD8- TCR alpha beta + cells bearing several NK cells markers such NK1.1 and Ly-49.
|
1466 |
8943570
|
In the present experiments, the addition of exogenous IL-7 completely restored IL-4 production by anti-TCR alpha beta-stimulated mature (HSA-CD8-) thymocytes in NOD mice.
|
1467 |
8943570
|
A short 2 h preincubation with IL-7 was sufficient to restore both the expression of IL-4 mRNA and IL-4 production capacity.
|
1468 |
8943570
|
This was related to a direct effect on NK1+ thymocytes since: (i) the effect of IL-7 was restricted to the non-mainstream MEL-14- 3G11- TCR alpha beta + subset which mostly concentrates the IL-4-producing capacity and (ii) IL-7 did not restore IL-4 production in class I-deficient mice which lack the NK1+ T cell subset.
|
1469 |
8943570
|
These results were extended in vivo by showing that the IL-7 treatment significantly increased the anti-CD3 triggered IL-4 production by NK1+ T spleen cells.

|
Using analytical fluorescent cell cytometry we quantitated the percentages of CD4, and CD8 T-cells, B-cells and macrophages and the percentages of these subsets expressing interleukin-2 (IL-2R), prolactin (PRLR) and Hi-intensity PRL (Hi-PRLR) receptors.
|
1473 |

Evaluation of T-splenocytes indicated a 2:1 ratio of CD4 to CD8 T-lymphocytes in the spleen.
|
1474 |

|
Pancreatic immunocompetent cell subsets expressed lower percentages of IL-2R, PRLR and Hi-PRLR compared to splenocytes.
|
1475 |
8953520
|
The results did not demonstrate any dramatic differences in the immunocompetent cell populations of the spleen or pancreas between male and female animals, however we were able to establish the percentage of immunocompetent cells with IL-2R, PRLR and Hi-PRLR as a reference for future studies.

To investigate whether the immunosuppressive neuropeptide calcitonin gene-related peptide (CGRP) was a potential candidate for tissue-specific gene therapy, we engineered nonobese diabetic (NOD) mice to produce CGRP in beta cells by placing the modified calcitonin gene under the control of the rat insulin promoter.
|
1495 |

|
CGRP inhibits CD4 T cell production of the cytokines that have been implicated in the pathogeny of type I diabetes.
|
1496 |

Lymphocytes from 77 newly diagnosed IDDM patients, 58 IDDM patients with disease duration > 6 months and 30 non-diabetic controls (including patients with several inflammatory conditions) were analyzed for membrane expression of CD4, CD8, CD45RA, CD45RO and CD27 molecules by FACS analysis.
|
1501 |
9115575
|
However, the percentage of CD4+ T cells, and consequently the CD4/CD8 ratio were significantly increased in PBL of recently diagnosed diabetic patients compared to the non-diabetic control group (P < 0.005).

RIP-LCMV transgenic mice that express the viral glycoprotein (GP) or nucleoprotein (NP) from lymphocytic choriomeningitis virus (LCMV) under control of the rat insulin promoter (RIP) in pancreatic beta-cells develop autoimmune diabetes (IDDM) after infection with LCMV.
|
1528 |
9218748
|
The present study shows that upregulation of MHC class II molecules associated with the attraction/activation of antigen presenting cells (APCs) to the islets occurs as soon as 2 days after LCMV inoculation of transgenic mice, clearly before CD4+ and CD8+ lymphocytes are found entering the islets (days 6 and 7 after LCMV inoculation).

BCG vaccination prevents insulin-dependent diabetes mellitus (IDDM) in NOD mice after disease acceleration with cyclophosphamide.
|
1530 |
9218754
|
We have previously shown that immunotherapy with complete Freund's adjuvant (CFA) or BCG is highly effective in the prevention of spontaneous insulin-dependent diabetes mellitus (IDDM) and in circumventing the rejection of syngeneic islet grafts in diabetic NOD mice.
|
1531 |
9218754
|
The comprehensive effect of BCG vaccination on cytokine production in Cy-treated mice was to increase IL-4 production and change the IL-4/IFN-gamma ratio in both serum and supernatant of spleen cell cultures.
|
1532 |

Molecular role of TGF-beta, secreted from a new type of CD4+ suppressor T cell, NY4.2, in the prevention of autoimmune IDDM in NOD mice.
|
1534 |
9218758
|
A new type of CD4+ T cell clone (NY4.2) isolated from pancreatic islet-infiltrated lymphocytes of acutely diabetic non-obese diabetic (NOD) mice prevents the development of insulin-dependent diabetes mellitus (IDDM) in NOD mice, as well as the recurrence of autoimmune diabetes in syngeneic islet-transplanted NOD mice.
|
1535 |
9218758
|
This investigation was initiated to determine the molecular role TGF-beta plays in the prevention of autoimmune IDDM by determining its effect on IL-2-induced signal transduction in Con A-activated NOD mouse splenocytes and HT-2 cells.
|
1536 |
9218758
|
Second, we determined whether TGF-beta inhibits the activation of Janus kinases (JAKs), as well as signal transducers and activators of transcription (STAT) proteins, involved in an IL-2-induced signalling pathway that normally leads to the proliferation of T cells.
|
1537 |
9218758
|
We found that TGF-beta inhibited tyrosine phosphorylation of JAK1, JAK3, STAT3 and STAT5 in Con A blasts from NOD splenocytes and HT-2 cells.
|
1538 |
9218758
|
Third, we examined whether TGF-beta inhibits the cooperation between STAT proteins and mitogen-activated protein kinase (MAPK), especially extracellular signal-regulated kinase 2 (ERK2).
|
1539 |
9218758
|
We found that TGF-beta inhibited the association of STAT3 and STAT5 with ERK2 in Con A blasts from NOD splenocytes and HT-2 cells.
|
1540 |
9218758
|
On the basis of these observations, we conclude that TGF-beta may interfere with signal transduction via inhibition of the IL-2-induced JAK/STAT pathway and inhibition of the association of STAT proteins with ERK2 in T cells from NOD splenocytes, resulting in the inhibition of IL-2-dependent T cell proliferation.
|
1541 |

A new type of CD4+ T cell clone (NY4.2) isolated from pancreatic islet-infiltrated lymphocytes of acutely diabetic non-obese diabetic (NOD) mice prevents the development of insulin-dependent diabetes mellitus (IDDM) in NOD mice, as well as the recurrence of autoimmune diabetes in syngeneic islet-transplanted NOD mice.

This investigation was initiated to determine the molecular role TGF-beta plays in the prevention of autoimmune IDDM by determining its effect on IL-2-induced signal transduction in Con A-activated NOD mouse splenocytes and HT-2 cells.
|
1545 |
9218758
|
Second, we determined whether TGF-beta inhibits the activation of Janus kinases (JAKs), as well as signal transducers and activators of transcription (STAT) proteins, involved in an IL-2-induced signalling pathway that normally leads to the proliferation of T cells.
|
1546 |
9218758
|
We found that TGF-beta inhibited tyrosine phosphorylation of JAK1, JAK3, STAT3 and STAT5 in Con A blasts from NOD splenocytes and HT-2 cells.
|
1547 |
9218758
|
Third, we examined whether TGF-beta inhibits the cooperation between STAT proteins and mitogen-activated protein kinase (MAPK), especially extracellular signal-regulated kinase 2 (ERK2).
|
1548 |
9218758
|
We found that TGF-beta inhibited the association of STAT3 and STAT5 with ERK2 in Con A blasts from NOD splenocytes and HT-2 cells.
|
1549 |
9218758
|
On the basis of these observations, we conclude that TGF-beta may interfere with signal transduction via inhibition of the IL-2-induced JAK/STAT pathway and inhibition of the association of STAT proteins with ERK2 in T cells from NOD splenocytes, resulting in the inhibition of IL-2-dependent T cell proliferation.

TGF-beta-mediated suppression of T cell activation may be responsible for the prevention of effector T cell-mediated autoimmune IDDM in NOD mice by TGF-beta-producing CD4+ suppressor T cells.

Autoimmune diabetes is caused by the CD4(+), T helper 1 (Th1) cell-mediated apoptosis of insulin-producing beta cells.

Moreover, the Th2-mediated destruction of islet cells was mediated by local interleukin-10 (IL-10) production but not by IL-4.

Glutamic acid decarboxylase isoform 2 (GAD65; EC 4.1.1.15) has been identified as a key target autoantigen of insulin-dependent diabetes mellitus (IDDM).
|
1563 |
9223318
|
IDDM is genetically associated with the major histocompatibility complex (MHC), and particular alleles from the HLA-DQ and HLA-DR loci contribute to disease.
|
1564 |
9223318
|
We have utilized HLA-DR(alpha1*0101,beta1*0401) (hereafter referred to as DR0401), human CD4, murine class II null triple transgenic mice and recombinant GAD65 to generate T cell hybridomas, and we have used overlapping sets of peptides to map the immunodominant epitopes of this autoantigen.
|
1565 |
9223318
|
Immunodominant GAD65 epitopes defined in transgenic mice correspond to GAD65 regions previously shown to elicit T cell responses specifically in DR0401 IDDM patients, underscoring the validity of this approach.

After allogeneic co-culture, lymphocyte activation was found by an increased release of the cytokines interferon-gamma, interleukin 2, and macrophage inflammatory protein 2, as well as by an enhanced expression of the interleukin 2 receptor on CD4+ T and CD8+ T cells.
|
1567 |
9275116
|
These changes comprised not only the enhancement of MHC class I and intercellular adhesion molecule 1 but also the induction of MHC class II antigens on pancreatic beta cells.

With this approach, two peptides were identified that stimulate the beta cell-reactive CD4+ T cell clone 1c10, which was isolated from a newly diagnosed insulin-dependent diabetes mellitus patient.

PGAI, also called APECED (autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy), is an autosomal recessive disorder, appearing in childhood and typically characterized by hypoparathyroidism (unusual in PGAII and PGAIII) and adrenal insufficiency.
|
1570 |
9304048
|
In APECED, autoimmune destruction of the pancreatic beta cells with development of insulin-dependent type 1 diabetes is possible, but less frequent than in the other PGAs, especially PGAII.
|
1571 |

In this patient no organo-specific antibodies were detected and the only immunologic disorder was a small decrease of CD3 and CD4/CD8 ratio, both CD4 and CD8 being at the lower normal range.

Here we demonstrate that transgenic mice expressing both TNFalpha and the Leishmania major LACK antigen in the pancreas (RIP-TNFalpha/RIP-LACK) exhibit an impaired ability to mount a CD4+ T cell response against LACK.
|
1574 |
9324360

In addition, peripheral CD4+ T cells from TCR transgenic mice (TCR-LACK/RIP-TNFalpha/RIP-LACK) produced reduced interleukin-2 but elevated levels of T helper 2 cytokines in response to LACK peptide in vitro.

It has been established that insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice results from a CD4+ and CD8+ T cell-dependent autoimmune process directed against the pancreatic beta cells.

Here we have investigated whether naive beta cell-specific CD8+ and CD4+ T cells can spontaneously accumulate in pancreatic islets, differentiate into effector cells, and destroy beta cells in the absence of other T cell specificities.
|
1582 |
9362527
|
We show that while RAG-2(-/-) 4.1-NOD mice, which only bear beta cell-specific CD4+ T cells, develop diabetes as early and as frequently as RAG-2+ 4.1-NOD mice, RAG-2(-/-) 8.3-NOD mice, which only bear beta cell-specific CD8+ T cells, develop diabetes less frequently and significantly later than RAG-2(+) 8.3-NOD mice.
|
1583 |
9362527
|
The monoclonal CD8+ T cells of RAG-2(-/-) 8.3-NOD mice mature properly, proliferate vigorously in response to antigenic stimulation in vitro, and can differentiate into beta cell-cytotoxic T cells in vivo, but do not efficiently accumulate in islets in the absence of a CD4+ T cell-derived signal, which can be provided by splenic CD4+ T cells from nontransgenic NOD mice.
|
1584 |
9362527
|
These results demonstrate that naive beta cell- specific CD8+ and CD4+ T cells can trigger diabetes in the absence of other T or B cell specificities, but suggest that efficient recruitment of naive diabetogenic beta cell-reactive CD8+ T cells to islets requires the assistance of beta cell-reactive CD4+ T cells.

IL-4 prevents insulitis and insulin-dependent diabetes mellitus in nonobese diabetic mice by potentiation of regulatory T helper-2 cell function.
|
1616 |
9366391
|
Beginning at the time of insulitis, nonobese diabetic (NOD) mice demonstrate a thymocyte and peripheral T cell proliferative hyporesponsiveness induced by TCR cross-linking, which is associated with reduced IL-2 and IL-4 secretion.
|
1617 |
9366391
|
We previously reported that NOD CD4+ T cell hyporesponsiveness is reversed completely in vitro by exogenous IL-4, and that administration of IL-4 to NOD mice prevents the onset of insulin-dependent diabetes mellitus (IDDM).
|
1618 |
9366391
|
In the present study, we tested this possibility by analysis of the mechanisms of protection from IDDM afforded by IL-4 treatment in NOD mice.
|
1619 |
9366391
|
We show that IL-4 protects NOD mice from insulitis and IDDM when administered i.p. three times a week for 10 wk beginning at 2 wk of age.
|
1620 |
9366391
|
Thus, IL-4 treatment favors the expansion of regulatory CD4+ Th2 cells in vivo and prevents the onset of insulitis and IDDM mediated by autoreactive Th1 cells.

GAD-reactive CD4+ Th1 cells induce diabetes in NOD/SCID mice.
|
1632 |
9421467
|
Although glutamic acid decarboxylase (GAD) has been implicated in IDDM, there is no direct evidence showing GAD-reactive T cells are diabetogenic in vivo.
|
1633 |
9421467
|
Splenocytes from this mouse showed a proliferative response to purified GAD, and were used to generate a CD4+ T cell line, designated 5A, that expresses TCRs encoding Vbeta2 and Vbeta12. 5A T cells exhibit a MHC restricted proliferative response to purified GAD, as well as GAD65 peptide 524-543.
|
1634 |
9421467
|
After antigen-specific stimulation, 5A T cells secrete IFNgamma and TNFalpha/beta, but not IL-4.
|
1635 |
9421467
|
We conclude that GAD injection in young NOD mice may, in some cases, provoke diabetes due to the activation of diabetogenic T cells reactive to GAD65 peptides.

Our data provide direct evidence that GAD65 autoimmunity may be a critical event in the pathogenesis of IDDM.

To elucidate the mechanism of susceptibility to tuberculosis infection in patients with diabetes mellitus, we measured IFN-gamma, IL-12 and IL-10 productions by CD4+ alpha beta T cells and autologous monocytes stimulated with live BCG in patients with pulmonary tuberculosis complicated with DM (TB + DM) or without DM (TB) and healthy controls.

Continuous antigenic stimulation in vivo can result in the generation of so-called "anergic" CD4(+) or CD8(+) T cells that fail to proliferate upon antigenic stimulation and fail to develop cytolytic effector functions.
|
1650 |
9432975
|
Furthermore, HA-specific T cells anergized in vivo contain higher levels of interleukin (IL)-4 messenger RNA (mRNA) than naive and recently activated T cells with the same specificity and more than a 100-fold higher levels of IL-10 mRNA.

Human and mouse major histocompatibility complex class II beta chain alleles associated with predisposition to type I diabetes often encode a non-charged residue at position 57 rather than the negatively charged aspartate residue characteristic of non-susceptible haplotypes.

Moreover, in both NOD and B6 mice, CD4+ T cells were more resistant to PCD induced by IL-2 deprivation than CD8+ cells.

In relation with this increased resistance to apoptosis, expression of the anti-apoptotic Bcl-x protein was upregulated in activated T cells of NOD mice, most notably after 24 h of IL-2 deprivation.

Approximately one-half of Caucasians with newly diagnosed insulin-dependent diabetes mellitus (IDDM) have autoantibodies to insulin, and the majority of those express the HLA-DR4 genotype [Ziegler, R., Alper, C.
|
1657 |
9520453
|
However, it has been difficult to demonstrate T cell proliferative responses to human insulin in IDDM patients [Durinovic-Bello, I., Hummel, M.
|
1658 |
9520453
|
We have immunized transgenic mice expressing the susceptible HLA-DR (alpha1*0101,beta1*0401) (hereafter called DRB1*0401) and human CD4 molecules on a murine major histocompatibility complex class II null background, with human preproinsulin (PPI), proinsulin (PI), and insulin and derived large panels of T cell hybridomas to determine the immunogenic epitopes of these proteins.
|
1659 |

|
These findings may partly explain why susceptibility to type 1 diabetes is associated with HLA-DR4-positive individuals and why T cell responses to the mature insulin protein are rarely detected in IDDM patients.

alpha/beta-T cell receptor (TCR)+CD4-CD8- (NKT) thymocytes prevent insulin-dependent diabetes mellitus in nonobese diabetic (NOD)/Lt mice by the influence of interleukin (IL)-4 and/or IL-10.
|
1661 |
9529321
|
We have previously shown that nonobese diabetic (NOD) mice are selectively deficient in alpha/beta-T cell receptor (TCR)+CD4-CD8- NKT cells, a defect that may contribute to their susceptibility to the spontaneous development of insulin-dependent diabetes mellitus (IDDM).

A single intravenous injection of 10(6) CD4-/lowCD8- or CD4-CD8- thymocytes from female (BALB/c x NOD)F1 donors protected intact NOD mice from the spontaneous onset of clinical IDDM.
|
1663 |
9529321
|
When alpha/beta-TCR+ and alpha/beta-TCR- subsets of CD4-CD8- thymocytes were transferred with diabetogenic splenocytes and compared for their ability to prevent the development of IDDM in irradiated adult recipients, only the alpha/beta-TCR+ population was protective, confirming that NKT cells were responsible for this activity.
|
1664 |
9529321
|
The protective effect in the induced model of IDDM was neutralized by anti-IL-4 and anti-IL-10 monoclonal antibodies in vivo, indicating a role for at least one of these cytokines in NKT cell-mediated protection.

Islet grafts and spleens from TNF-alpha-treated mice at 10 days after islet transplantation contained significantly fewer CD4+ and CD8+ T cells, and significantly decreased mRNA levels of type 1 cytokines (IFN-gamma, IL-2, and TNF-beta) than islet grafts and spleens from control mice.
|
1678 |

Regarding type 2 cytokines, IL-4 mRNA levels were not changed significantly in islet grafts or spleens of TNF-alpha-treated mice, whereas IL-10 mRNA levels were decreased significantly in islet grafts of TNF-alpha-treated mice and not significantly changed in spleens.

These results suggest that TNF-alpha partially protects beta cells in syngeneic islet grafts from recurrent autoimmune destruction by reducing CD4+ and CD8+ T cells and down-regulating type 1 cytokines, both systemically and locally in the islet graft.

Sequestration of CD4-associated Lck from the TCR complex may elicit T cell hyporesponsiveness in nonobese diabetic mice.

The Lck protein tyrosine kinase associates noncovalently with the cytoplasmic domain of CD4.

Oral administration of insulin to NOD mice suppresses or delays the onset of diabetes by skewing the response toward CD4+ Th2 cells and TGF-beta producing cells.
|
1767 |
9576014
|
When cytokine profiles were examined, feeding led to a predominance of IL-10 and TGF-beta production.
|
1768 |

|
Furthermore, feeding SEA in combination with insulin B-chain augmented the level of IL-10 production to insulin.
|
1769 |

T-cell lines established from SEA-fed and -immunized mice secreted IL-4 and IL-10 cytokines whereas the T-cell lines from control-fed mice immunized with SEA secreted predominantly IL-2 and IFN-gamma.
|

These results demonstrate that orally administered insulin can induce regulatory T-cells secreting IL-4, IL-10, and TGF-beta and that Th2 responses to oral insulin could be augmented in a synergistic way by feeding SEA and insulin B-chain together.

|
The CD4+ T cells secrete IFN-gamma and IL-2.
|
1775 |

IFN-gamma activates other resting macrophages, which, in turn, release cytokines, such as IL-1beta, TNF-alpha, and free radicals, which are toxic to beta cells.
|
1776 |
9583742
|
During this process, IL-2 and other cytokines induce the migration of CD8+ peripheral T cells to the inflamed islets, perhaps by inducing the expression of a specific homing receptor.
|
1777 |
9583742
|
The precytotoxic CD8+ T cells that bear beta cell-specific autoantigen receptors differentiate into cytotoxic effector T cells upon recognition of the beta cell-specific peptide bound to MHC class I molecules in the presence of beta cell-specific CD4+ T helper cells.
|
1778 |
9583742

In this way, macrophages, CD4+ T cells, and CD8+ T cells synergistically destroy beta cells, resulting in the onset of autoimmune IDDM.

|
The CD4+ T cells secrete IFN-gamma and IL-2.
|
1789 |
9583742
|
IFN-gamma activates other resting macrophages, which, in turn, release cytokines, such as IL-1beta, TNF-alpha, and free radicals, which are toxic to beta cells.
|
1790 |
9583742
|
During this process, IL-2 and other cytokines induce the migration of CD8+ peripheral T cells to the inflamed islets, perhaps by inducing the expression of a specific homing receptor.
|
1791 |
9583742
|
The precytotoxic CD8+ T cells that bear beta cell-specific autoantigen receptors differentiate into cytotoxic effector T cells upon recognition of the beta cell-specific peptide bound to MHC class I molecules in the presence of beta cell-specific CD4+ T helper cells.

To elucidate the relative importance of each of the subsets of cells, the NOD-rat insulin promoter (RIP)-B7-1 animals were crossed with NOD.beta2microglobulin -/- mice which lack major histocompatibility complex class I molecules and are deficient in peripheral CD8 T cells, NOD.CD4 -/- mice which lack T cells expressing CD4, and NOD.muMT -/- mice which lack B220-positive B cells.
|

To better define prevailing activation of circulating T cell subsets in insulin-dependent diabetes mellitus (IDDM) of recent onset (DM; n = 31; median age +/- SD, 28 +/- 6.9 yr) and of long standing (DML; n = 27; age, 33 +/- 10.4 yr; median duration of disease, 105 months), CD4+ and CD8+ T cells were analyzed to determine their naive and memory subsets as well as their expression of human leukocyte antigen (HLA)-DR, interleukin-2 receptor alpha-chain (CD25), and CD69 by three-color flow cytometry.
|
1820 |
9626161

T-cell reactivity and autoantibodies to several islet proteins such as insulin, GAD and IA-2 are associated with IDDM in mice and men.

|
We have isolated and characterized a human insulin-specific T-cell clone that was derived from peripheral blood of a newly diagnosed IDDM patient.
|
1855 |
9650096
|
Functionally, the human insulin-specific CD4+ T cells displayed a Th1/0 like cytokine profile and were restricted by HLA-DR.
|
1856 |
9650096
|
Our results indicate that human clonal T cells isolated from a recent onset IDDM patient recognize an epitope overlapping with the insulin B-chain region that is immunodominant and potentially therapeutic in NOD mice.
|
1857 |
9650096
|
This observation may be useful in studying the role of insulin-specific T cells in IDDM, and may eventually help to establish peptide-based immunotherapies in IDDM.

Correlation studies between cytokines expressed in islets and autoimmune diabetes development in NOD mice and BB rats have demonstrated that beta-cell destructive insulitis is associated with increased expression of proinflammatory cytokines (IL-1, TNF alpha, and IFN alpha) and type 1 cytokines (IFN gamma, TNF beta, IL-2 and IL-12), whereas non-destructive (benign) insulitis is associated with increased expression of type 2 cytokines (IL-4 and IL-10) and the type 3 cytokine (TGF beta).
|
1859 |
9679667
|
Cytokines (IL-1, TNF alpha, TNF beta and IFN gamma) may be directly cytotoxic to beta-cells by inducing nitric oxide and oxygen free radicals in the beta-cells.
|
1860 |
9679667
|
In addition, cytokines may sensitize beta-cells to T-cell-mediated cytotoxicity in vivo by upregulating MHC class I expression on the beta-cells (an action of IFN gamma), and inducing Fas (CD95) expression on beta-cells (actions of IL-1, and possibly TNF alpha and IFN gamma).
|
1861 |
9679667
|
Transgenic expression of cytokines in beta-cells of non-diabetes-prone mice and NOD mice has suggested pathogenic roles for IFN alpha, IFN gamma, IL-2 and IL-10 in insulin-dependent diabetes mellitus (IDDM) development, and protective roles for IL-4, IL-6 and TNF alpha.
|
1862 |
9679667
|
Islet-reactive CD4+ T-cell lines and clones that adoptively transfer IDDM into young NOD mice have a Th1 phenotype (IFN gamma-producing), but other islet-specific Th1 clones that produce TGF beta can adoptively transfer protection against IDDM in NOD mice.
|
1863 |
9679667
|
NOD mice with targeted deletions of IL-12 and IFN gamma genes still develop IDDM, albeit delayed and slightly less often.
|
1864 |
9679667
|
In contrast, post-natal deletions of IL-12 and IFN gamma, also IL-1, TNF alpha, IL-2, and IL-6--by systemic administrations of neutralizing antibodies, soluble receptors and receptor antagonists, and receptor-targeted cytotoxic drugs--significantly decrease IDDM incidence in NOD mice and/or BB rats.
|
1865 |
9679667
|
These cytokine deletion studies have provided the best evidence for pathologic roles for proinflammatory cytokines (IL-1, TNF alpha, and IL-6) and type 1 cytokines (IFN gamma, IL-2 and IL-12) in IDDM development.

Paracrine effect of transforming growth factor-beta1 (TGF-beta1) on autoimmune insulitis and diabetes was studied by transgenic production of the active form of porcine TGF-beta1 (pTGF-beta1) in pancreatic islet (islet) alpha cells in nonobese diabetic (NOD) mice under the control of rat glucagon promoter (RGP) (NOD-RGP-TGF-beta1).
|
1867 |
9691086
|
Based on these, it is concluded that autoimmune diabetes in NOD mice is not a systemic disease and it can be completely prevented by the paracrine TGF-beta1 in the islet compartment through protection against CD4(+) and CD8(+) effector lymphocytes.

Because this procedure is targeted directly at CD154, a co-activation molecule expressed predominantly by activated CD4+ T-cells, the results suggest that CD4+ cells have a major role in the cellular immune response to xenografts.

This clearly demonstrates that transient inactivation of most T-cells with anti-CD4 plus anti-CD8 mAbs effectively controls autoimmune disease in the isograft, despite recovery of CD4 and CD8 T-cells to normal levels.

In mice fed with pig spleen cells, as well as in control mice, the blocking of CD4 + T cells with mAbs led to abolition of proliferation (p < 0.002), while the blocking of CD8 + led to a less marked effect.
|
1876 |
9726599

The main change observed in mice fed with pig spleen cells was a marked increase in basal IL-10 production (p < 0.01) and the basal IL-10/IFNgamma ratio (p < 0.001).
|
1878 |
9726599
|
It seems likely that feeding with pig spleen cells shifted the Th1/Th2 balance towards a dominance of Th2-type class II-restricted CD4 + T cells, which may have been conducive to activating CD8 + suppressor T cells.

We demonstrate that IL-10 contributes early to the pathology of diabetes via a CD8+ T cell pathway, eliminating the requirement for B lymphocytes and CD40-CD40L costimulation.

|
These results indicate that nonaspartic acid residues at position 57 of class II MHC beta-chain is important for diabetogenic CD4+ T cell activation in the periphery but is not essential for the formation of a diabetogenic T cell repertoire in the thymus.

Compared with normal wound healing: (i) the CD4/CD8 ratio in chronic wounds was significantly lower (p < 0.0027) due to a relatively lower number of CD4+ T cells; (ii) a significantly higher number of macrophages was present in the edge of both type of chronic ulcers (p < 0.001 versus day 29 p.w.); and (iii) more B cells and plasma cells were detected in both type of chronic wounds compared with any day in the acute wound healing model (p < 0.04 for CD20+ and p < 0.01 for CD79a+ cells).

|
CD4+ or Th-lymphocytes will be activated after stimulation resulting in interferon-gamma (IFN-gamma) production by Th1-like lymphocytes and/or interleukin-4 (IL-4) secretion from Th2-like lymphocytes.
|
1910 |
9840449
|
In this study we have shown that this peptide activates Th1-like lymphocytes which produce increased amounts of IFN-gamma mRNA, but seldom mRNA for IL-4.
|

|
In conclusion, we suggest that GAD65 is involved in the development of type 1 diabetes and that the Th1-response may play a role in the destruction of beta cells.

A mechanism of autoimmune destruction of islet beta-cells in type 1 diabetes has been proposed to be the binding of Fas ligand (FasL) on T-cells to Fas receptors on beta-cells.
|
1915 |
9892218
|
We investigated this proposal by examining the expression of FasL and Fas on islet-infiltrating T-cells and beta-cells in relation to beta-cell destruction in a syngeneic islet transplant model in NOD mice.
|
1916 |
9892218
|
Two-color immunohistochemical assays revealed that FasL was expressed on CD4+ T-cells, CD8+ T-cells, and beta-cells in islet grafts from both diabetic and normoglycemic mice, and the percentage of each type of cell that expressed FasL was greater in islet grafts from normoglycemic compared with diabetic mice.
|
1917 |
9892218
|
In contrast, Fas was expressed on CD4+ T-cells, CD8+ T-cells, and beta-cells in islet grafts from diabetic mice, but it was nearly or totally absent on these cells in islet grafts from normoglycemic mice.
|
1918 |
9892218

Also, mRNA levels of interleukin (IL)-1alpha, tumor necrosis factor (TNF)-alpha, and interferon (IFN)-gamma were significantly lower in islet grafts from normoglycemic mice.

Finally, Fas was induced on NOD islet cells by incubation with IL-1beta, IFN-gamma, and the combination of IL-1beta, TNF-alpha, and IFN-gamma.
|

These findings support the concept that cytokine-induced Fas receptor expression on islet beta-cells is a mechanism for their destruction by FasL-expressing CD4+ and CD8+ T-cells and, possibly, by FasL-expressing beta-cells themselves.

|
1936 |
9892610
|
Previous studies have shown that induction of autoimmune diabetes by adult thymectomy and split dose irradiation of PVG.RT1(u) rats can be prevented by their reconstitution with peripheral CD4(+)CD45RC-TCR-alpha/beta+RT6(+) cells and CD4(+)CD8(-) thymocytes from normal syngeneic donors.

9892610
|
RT1(u) rats, development of thyroiditis was prevented by the transfer of CD4(+)CD45RC- and CD4(+)CD8(-) thymocytes from normal donors but not by CD4(+)CD45RC+ peripheral T cells.
|
1938 |
9892610
|
We now show that transforming growth factor (TGF)-beta and interleukin (IL)-4 both play essential roles in the mechanism of this protection since administration of monoclonal antibodies that block the biological activity of either of these cytokines abrogates the protective effect of the donor cells in the recipient rats.
|
1939 |
9892610
|
The prevention of both diabetes and thyroiditis by CD4(+)CD45RC- peripheral cells and CD4(+)CD8(-) thymocytes therefore does not support the view that the mechanism of regulation involves a switch from a T helper cell type 1 (Th1) to a Th2-like response, but rather relies upon a specific suppression of the autoimmune responses involving TGF-beta and IL-4.

Here we show that the transfer was most effective when both CD4+ and CD8+ T cells were present in the infiltrate, but CD4+ T cells alone were sufficient to cause the disease.

|
We found that islets deficient in Fas, IFN-gamma receptor, or inducible nitric oxide synthase had normal diabetes development; however, the specific lack of TNF- alpha receptor 1 (p55) afforded islets a profound protection from disease by altering the ability of islet-reactive, CD4(+) T cells to establish insulitis and subsequently destroy islet beta cells.

We used reverse transcriptase polymerase chain reaction (PCR) and quantitative PCR techniques to examine mRNA expression of interferon (IFN)-gamma (Th1 type cytokine), and interleukin (IL)-4 (Th2 type cytokine) in splenic cells.

To address the question of whether the cell death-inducing cytokines TNF and lymphotoxin alpha are involved in this process, we generated nonobese diabetic (NOD) mice that are deficient for TNF receptor 1 (TNFR1 or TNFRp55).
|
2107 |
10201999
|
Since this was probably due to the complex immunomodulatory effects of TNF and lymphotoxin alpha signaled via TNFR1 on lymphohemopoietic cells, adoptive transfer experiments with spleen cells from diabetic NOD mice were conducted.
|
2108 |
10201999
|
Together with the described expression patterns of perforin and TNF in the mononuclear islet infiltrates of NOD mice, these results indicate that two diabetogenic effector mechanisms are delivered by distinct cell populations: CD8+ T cells lyse beta cells via perforin-dependent cytotoxicity, whereas CD4+ T cells, macrophages, and dendritic cells contribute to diabetes development via TNFR1-dependent beta cell toxicity.

It is proposed that apoptosis commonly occurs in islet-infiltrating lymphocytes and that in the scid/scid adoptive-transfer model, the first islet-infiltrating cells are destroyed by programmed cell death independent of Fas ligand.

Jejuna of patients with insulin-dependent diabetes mellitus (IDDM) show signs of immune activation.
|
2122 |
10209507
|
The roles of enteric viruses and food antigens as possible triggers in human insulin-dependent diabetes mellitus and the evidence that mucosal-associated homing receptors are important in both human and experimental diabetes prompted us to undertake an immunohistochemical study of intestinal specimens from patients with IDDM.
|
2123 |
10209507
|
We studied jejunal morphology and immunohistochemistry in 26 patients with IDDM, 13 of whom had the HLA-DQB1*0201 gene and therefore a higher risk of coeliac disease.
|
2124 |
10209507
|
The densities of T cells, CD4+, CD8+, and T cell receptor alpha/beta+ and gamma/delta+ cells in the epithelium and lamina propria were similar in patients and controls, but the patients had significantly more alpha 4/beta 7 integrin+ cells in the lamina propria (P = 0.006).
|
2125 |

|
In support of this interpretation, we found that the accessory molecules CD4, CD44, and B7-1 (all of which are involved in T cell co-stimulation) were cleaved by Phlogenzym, while CD3 and MHC class II molecules (which are involved in the recognition of antigens by T cells) and LFA-1 were unaffected.

|
MHC class I and II molecules play a central role in the immune response against a variety of invading microorganisms and cells that have undergone malignant transformation by shaping the T cell repertoire in the thymus and by presenting peptide antigens from endogenous and exogenous antigens in the periphery to CD8+ cytotoxic T cells and CD4+ helper T cells.

After activation in vitro with islet cell membrane antigens, the diabetes-inducing cell lines were comprised of both CD4+ CD8- T-cells and 10-30% B-cells.

Therefore, in order to evaluate cytokine secretion by spleen and islet infiltrating T cells in NOD mice at different stages of the autoimmune process, we developed an ELISPOT assay that detects IL-2, IL-4, and interferon-gamma (IFN-gamma) secretion in vitro at the single-cell level.
|
2129 |
10337011
|
We showed that, whatever the age considered, IFN-gamma is predominantly secreted, and that no IL-4-secreting cells are detected in the islets of male and female NOD mice.
|
2130 |
10337011
|
Spleen cells from 8-week-old female NOD mice, which include regulatory suppressor T cells, do not secrete IL-4, either upon presentation of islet cell antigens in vitro, or after transfer in vivo, but do secrete IFN-gamma.
|
2131 |
10337011
|
IFN-gamma secretion by T cells from diabetic mice results from CD4 but not CD8 T cells in transfer experiments into NOD/severe combined immunodeficient (SCID) recipients.
|
2132 |
10337011
|
These results suggest that (i) detection of regulatory CD4 T cells in NOD mice is not paralleled by a Th2 response; (ii) beta cell destruction does not depend on a switch from a Th2 to a Th1-type response; and (iii) CD8 T cells do not participate in induction of diabetes by secreting IFN-gamma.

Chemokine receptor CCR2 and CCR5 polymorphisms in children with insulin-dependent diabetes mellitus.
|
2140 |
10400139
|
Studies have shown the important roles of several regulatory and proinflammatory cytokines in insulin-dependent diabetes mellitus (IDDM).
|
2141 |
10400139
|
CC-chemokine receptors CCR2 and CCR5 bind chemokines that are involved in the trafficking of leukocytes in both basal and inflammatory states.
|
2142 |
10400139
|
A common 32-bp deletion mutation in the CCR5 gene (CCR5delta32) and a G-to-A nucleotide substitution in the CCR2 at position 190 (CCR2-64I) have recently been described.
|
2143 |
10400139
|
The role of this mutation in IDDM cannot be explained yet, but, because CCR2 mediates the chemotaxis of CD4+ and CD8+ T cells to areas of inflammation and because these cells play important roles in insulitis, a mutation in the CCR2 gene may contribute to the susceptibility to the disease.
|
2144 |
10400139
|
According to these results, the CCR2 gene may be a new candidate for the susceptibility locus of IDDM.

Mice expressing lymphocytic choriomeningitis virus nucleoprotein (LCMV-NP) as a transgene in their beta cells develop insulin-dependent diabetes mellitus (IDDM) only after LCMV infection.

|
Inoculation of plasmid DNA encoding the insulin B chain reduced the incidence of IDDM by 50% in this model.
|
2147 |
10411548
|
The insulin B-chain DNA vaccination was effective through induction of regulatory CD4 lymphocytes that react with the insulin B chain, secrete IL-4, and locally reduce activity of LCMV-NP-autoreactive cytotoxic T lymphocytes in the pancreatic draining lymph node.

The ability of nonobese diabetic (NOD) mice to mount a cellular immune response to the secretory granule protein tyrosine phosphatase (PTP), phogrin was evaluated by immunization of 8- to 12-week-old animals with recombinant phogrin in complete Freund's adjuvant.
|
2149 |
10426369
|
The results demonstrate the feasibility of generating antigen-specific diabetes-inducing CD4+ cells by direct immunization of NOD mice and their potential use for further studies of the antigenic epitopes in the PTP family members.

Prevalent CD8(+) T cell response against one peptide/MHC complex in autoimmune diabetes.
|
2151 |
10430939
|
Spontaneous autoimmune diabetes in nonobese diabetic (NOD) mice is the result of a CD4(+) and CD8(+) T cell-dependent autoimmune process directed against the pancreatic beta cells.
|
2152 |
10430939
|
Here, we define the structure of a peptide mimotope that elicits the proliferation, cytokine secretion, differentiation, and cytotoxicity of a diabetogenic H-2K(d)-restricted CD8(+) T cell specificity (NY8.3) that uses a T cell receptor alpha (TCRalpha) rearrangement frequently expressed by CD8(+) T cells propagated from the earliest insulitic lesions of NOD mice (Valpha17-Jalpha42 elements, often joined by the N-region sequence M-R-D/E).
|
2153 |
10430939
|
Stimulation of splenic CD8(+) T cells from single-chain 8. 3-TCRbeta-transgenic NOD mice with this mimotope leads to preferential expansion of T cells bearing an endogenously derived TCRalpha chain identical to the one used by their islet-associated CD8(+) T cells, which is also identical to the 8.3-TCRalpha sequence.
|
2154 |
10430939
|
This work demonstrates that beta cell-reactive CD8(+) T cells mount a prevalent response against a single peptide/MHC complex and provides one peptide ligand for CD8(+) T cells in autoimmune diabetes.

CD4+ lymphocytes are the most important effector cells in autoimmune diabetes of NOD mice, although some role of CD8+ T cells has been demonstrated.

2156 |

However, it is unknown how CD4+ lymphocytes are able to destroy pancreatic beta-cells that do not express MHC (major histocompatibility complex) class II molecules.

Substantial benefits are associated with these responses: Initially memory, then naive, CD4 cell counts may rise by 150-200 cells/mm3; CD8 cell numbers also rise sharply but then fall below pretreatment levels, presumably as antigenic stimuli driving the CD8 response decline; cellular activation markers decline; distortions in the T cell repertoire gradually lessen; and increases in proliferative responses to mitogens and recall antigens are more easily elicited.

To fully characterize human glutamic acid decarboxylase (GAD)65 protein T-cell epitopes associated with insulin-dependent diabetes mellitus (IDDM), CTL clones specific to GAD65 protein antigens were isolated from two congenital rubella syndrome (CRS)-associated IDDM patients.
|
2173 |
10439311
|
Overlapping nonamer T-cell epitopes recognized by both CD4+ or CD8+ CTL clones within peptides GAD65(252-266) and GAD65(274-286) were identified as sequences bounded by GAD65(255-266) with 6/9 overlapping residues, and GAD65(276-285) with 8/9 overlapping residues, respectively, using two panels of overlapping peptide analogs in cytotoxicity assays.

In the past decade, a wealth of information has accumulated through studies in non-obese diabetic (NOD) mice regarding the molecular and cellular events that participate in the progression to diabetes in insulin-dependent diabetes mellitus (IDDM).
|
2190 |
10450504
|
Here we describe a new NOD model for analyzing the role of TNF-alpha in IDDM, TNF-alpha-NOD mice.
|
2191 |
10450504
|
Although adoptive transfer studies demonstrated that TNF-alpha can enhance presentation of islet antigen to both effector CD4+ and CD8+ T cells, further investigations in TNF-alpha-NOD mice deficient in either CD4+ or CD8+ T cells demonstrated that diabetes progression is dependent on CD8+ T cells, with CD4+ T cells playing a lesser role.
|
2192 |
10450504
|
The data accumulating from TNF-alpha-NOD mice, described in this review, indicates novel pathways by which inflammatory stimuli can precipitate autoimmunity, and suggests newer approaches in the design of therapeutic treatments that prevent beta-cell destruction in IDDM.
|

IL-12 and IL-12 antagonist administration to nonobese diabetic (NOD) mice accelerates and prevents insulin-dependent diabetes mellitus (IDDM), respectively.
|
2194 |
10453045
|
Nevertheless, wild-type and IL-12-deficient NOD mice developed similar insulitis and IDDM.
|
2195 |
10453045
|
Both in wild-type and IL-12-deficient NOD mice, approximately 20% of pancreas-infiltrating CD4+ T cells produced IFN-gamma, whereas very few produced IL-10 or IL-4, indicating that IDDM was associated with a type 1 T cell infiltrate in the target organ.

Pancreatic sections were also examined for the influx of CD4 and CD8 T cells and macrophages following immunofluorescence staining.

2199 |
10461865
|
The marked up-regulation of inducible nitric oxide synthase in a selective proportion of macrophages, within the islets, immediately preceding and during the onset of diabetes suggests that nitric oxide released by islet macrophages may be an important molecular mediator of beta cell destruction in this accelerated model of insulin-dependent diabetes mellitus.

Type 1 diabetes is an autoimmune disease in which the insulin-producing pancreatic beta cells are destroyed at an early age by an immune process that involves both CD4 and CD8 T lymphocytes.

Insulin-dependent diabetes mellitus (IDDM) in the nonobese diabetes (NOD) mouse model is thought to be an autoimmune CD4 Th1-like cell-mediated disease.
|
2213 |
10476932
|
We tested the efficacy of oral use of interferon-alpha (IFN-alpha) therapy on IDDM in NOD mice.
|
2214 |
10476932
|
Using urine and blood sugar levels as indicators of IDDM, oral administration of murine IFN-alpha (100 IU/body) to NOD mice significantly delayed the onset of symptomatic diabetes.
|
2215 |
10476932
|
However, oral use of IFN-alpha did not prevent diabetic NOD mice from losing weight once NOD mice were symptomatic, suggesting that orally administered IFN-alpha is a prophylactic rather than therapeutic approach to the management of IDDM.

10480600
|
We demonstrate that oral insulin feeding of NOD mice induces the function of insulin B-chain reactive CD4+ regulatory T-cells, which compete with diabetogenic effector T-cells for the recognition of insulin in NOD.Scid recipient mice.
|
2219 |

In a number of animal models of spontaneous autoimmune diabetes, pathogenesis has been highly correlated with autoreactive T-cell production of the type 1 cytokine interferon-gamma (IFN-gamma), while protection from disease was associated with type 2 cytokines such as interleukin (IL)-4.

IL-10 has generally been associated with immunosuppression, including the modulation of class II expression on antigen-presenting cells and the generation of regulatory CD4 T-cells.

Double transgenic (dTg) mice expressing the hemagglutinin (HA) of influenza virus under the insulin promoter and the TCR specific for the immunodominant CD4 T cell epitope of HA (HA110-120) develop insulin-dependent diabetes mellitus (IDDM).
|
2237 |

Type I diabetes, also known as insulin-dependent diabetes mellitus (IDDM) results from the destruction of insulin-producing pancreatic beta cells by a progressive beta cell-specific autoimmune process.
|
2238 |
10549569
|
Macrophages are primary contributors to the creation of the immune environment conducive to the development and activation of beta cell-specific Th1-type CD4+ T cells and CD8+ cytotoxic T cells that cause autoimmune diabetes in NOD mice.

|
CD4+ and CD8+ T cells are both believed to be important for the destruction of beta cells.
|
2240 |
10549569
|
In this way, macrophages, CD4+ T cells and CD8+ T cells act synergistically to kill the beta cells in conjunction with beta cell autoantigens and MHC class I and class II antigens, resulting in the onset of autoimmune type I diabetes.

Autoreactive CD4+ T cells protect from autoimmune diabetes via bystander suppression using the IL-4/Stat6 pathway.

2250 |

Here, we report the generation and characterization of insulin B chain-specific "autoreactive" CD4+ regulatory T cells that locally suppress diabetogenic T cell responses against an unrelated self-antigen (viral transgene) in a virus-induced model for type 1 diabetes.

The role of CD4 and CD8 T cells in the development of autoimmune diabetes.

10553062
|
The role of the STAT4 signaling pathway in autoimmune diabetes was investigated using the rat insulin promoter lymphocytic choriomeningitis virus model of virally induced autoimmune diabetes.
|
2255 |
10553062
|
Abrogation of STAT4 signaling significantly reduced the development of CD4+-T cell-dependent but not CD4+-T cell-independent diabetes, illustrating the fine-tuned kinetics involved in the pathogenesis of autoimmunity.
|
2256 |
10553062
|
However, the absence of STAT4 did not prevent the generation of autoreactive Th1/Tc1 T cell responses, as well as protective antiviral immunity.
|
2257 |
10553062
|
Protection from insulin-dependent diabetes mellitus was associated with decreased numbers of autoreactive CTL precursors in the pancreas and the spleen and a general as well as Ag-specific reduction of IFN-gamma secretion by T lymphocytes.
|
2258 |
10553062
|
Selective inhibition of the STAT4 signal transduction pathway might constitute a novel and attractive approach to prevent clinical insulin-dependent diabetes mellitus in prediabetic individuals at risk.
|
2259 |
10553102
|
As few as 500 CD4high islet-infiltrating CD4+ T cells transferred insulin-dependent diabetes mellitus to CD8 reconstituted NOD-SCID mice within 30 days of transfer.
|
2260 |
10553102
|
In contrast, CD4high T cells isolated from either NOD spleen or salivary glands did not transfer insulin-dependent diabetes mellitus into similar CD8-reconstituted NOD-SCID recipients.

Our group is examining the role that CD4(+) and CD8(+) T cells play in IDDM in the NOD mouse, as it is known that both T cell subsets are required for onset of disease.
|
2262 |

|
We raised GAD peptide-specific CD8(+) T cells by immunising NOD mice with the GAD peptide alongside an irrelevant peptide that induced a CD4(+) T cell response.
|
2263 |

In order to maintain these peptide specific T cells in vitro and generate clones, it was found that antibodies specific to CD4(+) and MHC class II molecules needed to be included in the culture medium.

Although CD8+ T-cells are observed within the grafts at later time points, CD4+ T-cells predominate until the graft is destroyed.

|
In the past few years, considerable evidence has accumulated to suggest the existence of functionally polarized responses by the CD4+ T helper (Th)--and the CD8+ T cytotoxic (Tc)-cell subsets that depend on the cytokines they produce.
|
2272 |

|
In vitro studies indicate that the effect of the Ab is independent of CD4 coreceptor function, as Ab treatment also inhibits proliferation and induces a persistent anergy in naive CD4 T cells stimulated by anti-CD3/CD28.

Both are used to model human insulin-dependent diabetes mellitus (IDDM).

We now report that the phenotype of NK T cells in the rat is alphabetaTcR+ CD8+ CD4-, comparable to the NK T cell phenotype reported for humans, which is alphabetaTcR+ CD4- Valpha24-JalphaQ, and either CD8- or CD8alphaalpha+.
|
2275 |

|
Because RT6+ T cells are deficient in DP-BB rats, and because depletion of cells expressing RT6 induces IDDM in DR-BB rats, we studied NK T cells for expression of this antigen.

|
The number of CD4- CD8-, CD4+ CD8-, CD4- CD8+ and CD4+ CD8+ subsets was not different between BBDP and BBDR rat thymocytes, whereas spleen and lymph nodes in BBDP rats undergo severe T-cell lymphopenia.
|
2277 |
10594693
|
Notably, mature CD4- CD8+ [T-cell receptor (TCR)-alphabeta+ and CD5+] cells are certainly present in the BBDP rat thymus, unlike some previous reports, suggesting that the differentiation of CD4- CD8+ from CD4+ CD8+ cells occurs normally in the BBDP rat thymus.

We now demonstrate that regulatory splenocytes belong to the CD4+ CD62Lhigh T cell subset that comprises a vast majority of naive cells producing low levels of IL-2 and IFN-gamma and no IL-4 and IL-10 upon in vitro stimulation.
|
2281 |
10605017
|
Consistently, the inhibition of diabetes transfer was not mediated by IL-4 and IL-10.
|
2282 |
10605017
|
The phenotypic and functional characteristics of protective CD4+ CD62L+ cells suggest they are different from Th2-, Tr1-, and NK T-type cells, reported to be implicated in the control of diabetes in NOD mice, and may represent a new immunoregulatory population.

In transgenic mice, we have expressed three human components involved in T-cell recognition of an MS-relevant autoantigen presented by the HLA-DR2 molecule: DRA*0101/DRB1*1501 (HLA-DR2), an MHC class II candidate MS susceptibility genes found in individuals of European descent; a T-cell receptor (TCR) from an MS-patient-derived T-cell clone specific for the HLA-DR2 bound immunodominant myelin basic protein (MBP) 4102 peptide; and the human CD4 coreceptor.
|
2287 |
10610182
|
When DR2 and TCR double-transgenic mice were backcrossed twice to Rag2 (for recombination-activating gene 2)-deficient mice, the incidence of spontaneous disease increased, demonstrating that T cells specific for the HLA-DR2 bound MBP peptide are sufficient and necessary for development of disease.
|
2288 |
10620608
|
The diabetes was accompanied by severe insulitis composed of both T cells (CD4(+) and CD8(+)) and B cells.
|
2289 |
10620608
|
T cells from the diabetic mice secreted large amounts of interferon gamma, but not interleukin 4, in response to DQ8(+) islets and the putative islet autoantigens, insulin and glutamic acid decarboxylase (GAD).
|
2290 |
10620608
|
In conclusion, substitution of HLA-DQA1*0301/DQB1*0302, but not HLA-DQA1*0103/DQB1*0601, for murine MHC class II provokes autoimmune diabetes in non-diabetes-prone rat insulin promoter (RIP).B7-1 C57BL/6 mice.

In the nonobese diabetic mouse model, there is new evidence that insulin plays an important role: not only is it an antigen for pathogenic CD4+ T cells but also it is recognised by highly diabetogenic CD8+ T cells.

|
Neonatal tumor necrosis factor alpha promotes diabetes in nonobese diabetic mice by CD154-independent antigen presentation to CD8(+) T cells.
|
2293 |
10637268
|
Here we show that TNF-alpha promotes autoaggression of both effector CD4(+) and CD8(+) T cells.
|
2294 |
10637268
|
Whereas CD8(+) T cells are critical for diabetes progression, CD4(+) T cells play a lesser role.
|
2295 |
10637268
|
TNF-alpha-mediated diabetes development was not dependent on CD154-CD40 signals or activated CD4(+) T cells.
|
2296 |
10637268
|
Instead, it appears that TNF-alpha can promote cross-presentation of islet antigen to CD8(+) T cells using a unique CD40-CD154-independent pathway.

Insulin-dependent diabetes mellitus (IDDM) is caused by autoimmune destruction of pancreatic beta cells with the primary mechanism being cell mediated.
|
2308 |
10668191
|
Since the diabetes-prone BB rat is lymphopenic, with a reduction of both CD4 and CD8 cells, the continuous failure of dCF treated animals to develop diabetes may have been due to generalized immunosuppression.

Here we show that CD4(+) T lymphocytes propagated from transgenic nonobese diabetic (NOD) mice expressing the highly diabetogenic, beta cell-specific 4.1-T-cell receptor (4.1-TCR) can kill IL-1alpha-, IL-1beta-, and IFN-gamma-treated beta cells from NOD mice.
|
2312 |
10683375
|
Abrogation of Fas expression in 4.1-TCR-transgenic NOD mice afforded nearly complete protection from diabetes and did not interfere with the development of the transgenic CD4(+) T cells or with their ability to cause insulitis.

Signals generated through CD28-B7 and CD40 ligand (CD40L)-CD40 interactions have been shown to be crucial for the induction of long-term allograft survivability.
|
2331 |
10684857

To investigate potential mechanisms of CD40L-induced allograft acceptance, we coimmobilized hu5C8 with suboptimal amounts of anti-CD3 to stimulate CD4(+) T cells.

We now report that anti-CD3/CD40L costimulation results in CD28-independent activation and subsequent deletion of resting T cells.

2333 |
10684857

Coligation of CD3 and CD40L increased expression of CD69, CD25, and CD54 on CD4(+) T cells.

We also found that costimulation with anti-CD3/CD40L resulted in enhanced production of interleukin (IL)-10, interferon gamma, and tumor necrosis factor alpha but not IL-2 or IL-6.

Consistent with that observation, anti-CD3/CD40L did not enhance the antiapoptotic proteins Bcl-2 and Bcl-xL.

Pretreatment of lymphocytes with soluble FasL (sFasL) also inhibited diabetes transfer. sFasL treatment decreased the number of CD4+CD45RBlow cells and increased the number of propidium iodide-stained cells among CD4+CD45RBlow cells, suggesting that sFasL induces apoptosis on CD4+CD45RBlow "memory" cells.

Furthermore, the mechanism by which diabetes is transferred by a Tg Th2 T cell clone differs from that of the original CD4+ Th1 BDC-2.5 T cell clone made in this laboratory.

Treatment of prediabetic mice with the pancreatic islet autoantigen insulin, by aerosol or intranasal delivery, reduces the incidence of diabetes and is associated with induction of CD8 (alpha alpha) gamma delta T cells, small numbers of which prevent adoptive transfer of diabetes.

10725754
|
Previous work has indicated that an important component for the initiation of autoimmune insulin-dependent diabetes mellitus (IDDM) in the NOD mouse model entails MHC class I-restricted CD8 T cell responses against pancreatic beta cell Ags.
|
2362 |
10725754
|
However, unless previously activated in vitro, such CD8 T cells have previously been thought to require helper functions provided by MHC class II-restricted CD4 T cells to exert their full diabetogenic effects.
|
2363 |
10725754
|
In this study, we show that IDDM development is greatly accelerated in a stock of NOD mice expressing TCR transgenes derived from a MHC class I-restricted CD8 T cell clone (designated AI4) previously found to contribute to the earliest preclinical stages of pancreatic beta cell destruction.
|
2364 |
10725754
|
Importantly, these TCR transgenic NOD mice (designated NOD.AI4alphabeta Tg) continued to develop IDDM at a greatly accelerated rate when residual CD4 helper T cells were eliminated by introduction of the scid mutation or a functionally inactivated CD4 allele.
|
2365 |
10725754
|
In a previously described stock of NOD mice expressing TCR transgenes derived from another MHC class I-restricted beta cell autoreactive T cell clone, IDDM development was retarded by elimination of residual CD4 T cells.
|
2366 |
10725754

Hence, there is variability in the helper dependence of CD8 T cells contributing to the development of autoimmune IDDM.

One of the primary mechanisms of active cellular suppression is via secretion of suppressive cytokines such as TGF-beta, IL-4, and IL-10 following antigen-specific triggering.
|
2401 |

TGF-beta is produced both by CD4+ and CD8+ GALT-derived T cells and is an important mediator of the active suppression component of oral tolerance.

The popliteal lymph node response to streptozotocin is under type 1, MHC class-I restricted, CD8(+) T-cell control.
|
2403 |
10773364
|
In order to determine whether PLN responses involve CD4(+) or CD8(+) T-cells, the effects of streptozotocin (STZ), a prototypic immunotoxic compound, were analyzed after injection into the hind footpad of C57 BL/6 mice and major histocompatibility complex (MHC) class I or II deficient mice.
|
2404 |
10773364
|
The involvement of type 1 or type 2 cell control on the production of cytokine mRNAs was analyzed in lymph node cells by quantitative RT-PCR, together with the analysis of a wide range of cytokine mRNAs after STZ injection (IL-1alpha, IL-1beta, TNF-alpha, IFN-gamma, IL-2, IL-2 receptor, IL-4, IL-5, IL-6, IL-10 and IL-12).
|
2405 |
10773364
|
We have found that mice depleted in CD8(+) T-cells did not respond to STZ, whereas mice depleted in CD4(+) T-cells exhibited the expected positive PLN responses, with increased weight and cellularity indices.
|
2406 |
10773364
|
STZ induced a low production of interleukin (IL)-2 mRNAs, a mild increase in IL-1alpha and IL-6 mRNAs production, and a dramatic increase in IFN-gamma, IL-1beta, TNF-alpha, IL-12 and IL-2 receptor mRNAs, which correlated with positive PLN responses.
|
2407 |
10773364
|
No effects on IL-4, IL-5 and IL-10 mRNAs synthesis were noted.
|
2408 |

In CD8(+) T-cell deficient mice, there was no production of IFN-gamma or IL-6 mRNAs.

Flow cytometric analysis then revealed that LPS-stimulation in vitro induced the expression of an IL-2 receptor (CD25) on CD4 T cells; this indicates that the activation of islet-specific T cells is a prerequisite to eliciting diabetes in this situation.

Although therapeutic injection of protein and synthetic peptides corresponding to CD4+ T cell epitopes has been shown to prevent or block autoimmune disease in several models, down-regulation of an ongoing CD8+ T cell-mediated autoimmune response using this approach has not yet been reported.

The identification of factors that regulate the proliferation and differentiation of double-positive (DP) into CD4(+) and CD8(+) single-positive (SP) thymocytes has proven difficult due to the inability of DP thymocytes to proliferate, expand, and differentiate into SP thymocytes in available cell culture media.

During a 5-day culture in XLCM in the absence of thymic stromal cells, DP thymocytes from normal mice and MHC double knockout mice (lack SP thymocytes) proliferate, expand, and differentiate into several (alphabetaTCR(+), NK1.1(+)alphabetaTCR(+), and gammadeltaTCR(+)) subsets of CD4(+) and predominantly CD8(+) SP thymocytes.

We found that both Th1-like CD45RC+CD4+ and cytotoxic CD8+ T cells were up-regulated, whereas Th2-like CD45RC-CD4+ T cells were down-regulated, and that isolated and activated CD45RC+CD4+ and CD8+ T cells from KRV-infected DR-BB rats induced autoimmune diabetes in young diabetes-prone BioBreeding (DP-BB) rats.
|
2440 |
10946320
|
We conclude that KRV-induced autoimmune diabetes in DR-BB rats is not due to molecular mimicry, but is due to a breakdown of the finely tuned immune balance of Th1-like CD45RC+CD4+ and Th2-like CD45RC-CD4+ T cells, resulting in the selective activation of beta cell-cytotoxic effector T cells.

Both CD4+ and CD8+ cells were detected in the IR(High) T cell population, but IR(High) expression was detected predominantly on CD4+ cells.
|
2444 |

The lack of IL-2 receptor and transferrin receptor expression as seen previously, together with the CD62L(Low)/- CD44(High) phenotype suggests that IR(High) T cells are memory cells.

In thoracic duct lymph, cells that could prevent diabetes were found in both CD25- and CD25+ subsets of CD4+CD45RC- cells.

CD25 is a marker for CD4+ thymocytes that prevent autoimmune diabetes in rats, but peripheral T cells with this function are found in both CD25+ and CD25- subpopulations.

We thus determined the cortisol response to an intravenous bolus of 1 microg ACTH in 21 controls, 18 HIV-positive (BMI 19.5+/-0.9 kg/m(2), albumin 24+/-1.4 g/l, CD4 count 192+/-47/mm(3)) and 22 HIV-negative (BMI 19.3+/-0.8 kg/m(2), albumin 29+/-1 g/l, CD4 count 652+/-76/mm(3)) patients with active PTB.

In vitro treatment of splenocytes with GT revealed relative decreases in CD4+ and increases in CD8+ T-cell subsets, whereas in vivo treatment with GT did not result in detectable alterations in relative CD4+ and CD8+ cell subsets.
|
2470 |
11079813

There were also significant decreases in CD4+ and CD8+ thymocytes and the proliferative response of splenocytes.

Our results suggest that the number and function of T cells in WF may be reduced, which may be related at least in part to elevated TNF-alpha levels, although the role of the other factors such as glucose, insulin, cholesterol, and triglycerides on T-cell immunity should be further investigated.

Furthermore, I-A(g7)/GAD peptide tetramer can detect most if not all of the antigen-specific CD4(+) T cells from immunized NOD mice.

The insulinoma-associated protein 2 (IA-2) is a phosphatase-like autoantigen inducing T and B cell responses associated with human insulin-dependent diabetes mellitus (IDDM).
|
2477 |
11120794
|
We now report that T cell responses to IA-2 can also be detected in the nonobese diabetic (NOD) mouse, a model of human IDDM.
|
2478 |
11120794
|
Cytokine secretion in response to purified mouse rIA-2, characterized by high IFN-gamma and relatively low IL-10 and IL-6 secretion, was elicited in spleen cells from unprimed NOD mice.
|
2479 |
11120794
|
Conversely, no response to IA-2 was induced in spleen cells from BALB/c, C57BL/6, or Biozzi AB/H mice that express, like NOD, the I-A(g7) class II molecule, but are not susceptible to spontaneous IDDM.
|
2480 |
11120794
|
The IA-2-induced IFN-gamma response in NOD spleen cells could already be detected at 3 wk and peaked at 8 wk of age, whereas the IL-10 secretion was maximal at 4 wk of age and then waned.
|
2481 |
11120794
|
IA-2-dependent IFN-gamma secretion was induced in CD4(+) cells from spleen as well as pancreatic and mesenteric lymph nodes.
|
2482 |
11120794
|
The biological relevance of the response to IA-2 is indicated by the enhanced IDDM following a single injection of the recombinant protein emulsified in IFA into 18-day-old NOD mice.
|
2483 |
11120794
|
In addition, IFN-gamma production in response to IA-2 and IDDM acceleration could be induced by IL-12 administration to 12-day-old NOD mice.
|
2484 |
11120794
|
These results identify IA-2 as an early T cell-inducing autoantigen in the NOD mouse and indicate a role for the IA-2-induced Th1 cell response in IDDM pathogenesis.
|

|
These include increased expression of proteasome processing proteins (LMP2), transporters of antigen peptides (TAP), invariant chain (Ii), HLA-DM, and the co-stimulatory molecule, B7, as well as STAT and NF-kappaB activation.
|
2486 |
11129119
|
A critical factor in these changes is the loss of normal negative regulation of MHC class I, class II, and thyrotropin receptor (TSHR) gene expression, which is necessary to maintain self-tolerance during the normal changes in gene expression involved in hormonally-increased growth and function of the cell.
|
2487 |
11129119
|
Self-tolerance to the TSHR is maintained in normals because there is a population of CD8- cells which normally suppresses a population of CD4+ cells that can interact with the TSHR if thyrocytes become APCs.

In a second transgenic model in which islet cells express the lymphocytic choriomeningitis virus nucleoprotein, the virus infection triggers autoimmune diabetes within a few weeks involving both CD4 and CD8 T-cells; here too transgenic c-Maf provided significant protection.

We identified a naturally presented autoantigen from the human islet antigen glutamic acid decarboxylase, 65-kDa isoform (GAD65), by using a combination of chromatography and mass spectrometry of peptides bound by the type I diabetes (insulin-dependent diabetes mellitus, IDDM)-associated HLA-DR4 molecule.

Peptides encompassing this epitope-stimulated GAD65-specific T cells from diabetic patients and a DR4-positive individual at high risk for developing IDDM.

This direct identification and manipulation of GAD65 epitope recognition provides an approach toward dissection of the complex CD4(+) T cell response in IDDM.

CD40 is constitutively expressed on marrow-derived cells such as dendritic cells and B lymphocytes and is induced by gamma interferon (IFN-gamma) on most somatic cells.

There was no difference between the acquisition of CD69 and CD154 by mesenteric lymph node T cells of C. parvum-infected animals with intact or disrupted CD40-CD154 pathways.
|
2494 |

CD4 T cells entered the intestinal laminae propriae of C. parvum-infected animals whether or not the CD40 genes of these recipients were intact.

CD4(+) T cells arise spontaneously in young NOD mice to an apparently dominant determinant found within the GAD65 peptide 530--543 (p530); however, T cells to the overlapping determinant 524-538 (p524) dominate the response only after immunization with GAD65(524--543).
|
2496 |
11207247
|
T cell clones and hybridomas from both of these T cell groups were responsive to APC pulsed with GAD65(524--543) or whole rGAD65. p524-reactive cells appeared to be regulatory upon adoptive transfer into young NOD mice and could inhibit insulin-dependent diabetes mellitus development, although they were unable to produce IL-4, IL-10, or TGF beta upon antigenic challenge.

Autoreactive T cells specific to these autoantigens are present in most normal individuals but are kept under control by a number of peripheral tolerance mechanisms, among which CD4(+) CD25(+) CD62L(+) T cell-mediated regulation probably plays a central role.

In this review, we summarize the current understanding of these complex costimulatory pathways including the individual roles of the CD28, CTLA-4, B7-1 (CD80), and B7-2 (CD86) molecules.
|
2500 |

This is most apparent in regulation of the CD4(+)CD25(+)CTLA-4(+) immunoregulatory T cells that control multiple autoimmune diseases.

Accumulating evidence suggests that CD4(+)T helper type 1 (Th1) cells play a major role in the development of insulin-dependent diabetes mellitus (IDDM) in the non-obese diabetic (NOD) mouse model.

To investigate the role of IL-12 that is locally produced by islet-infiltrating cells in the development of IDDM, we generated transgenic NOD mice in which the IL-12 p40 homodimer, a natural antagonist of IL-12, was produced exclusively in islets without affecting the levels of IL-12 p40 in the systemic circulation.
|
2503 |
11247635
|
These results clearly demonstrate that IL-12 locally produced by islet-infiltrating cells plays a critical role in the development of IDDM.
|

We screened synthetic peptide libraries dedicated to bind to HLA-DR3, which predisposes to both diseases, using clonal CD4(+) T cells reactive to GAD65 isolated from a prediabetic stiff-man syndrome patient.

Structural similarity (molecular mimicry) between viral epitopes and self-peptides can lead to the induction of autoaggressive CD4(+) as well as CD8(+) T cell responses.

One of these self-peptides, derived from tumor necrosis factor receptor I (FGPSNWHFM, amino acids 302-310), maintained LCMV-specific CD8(+) T cells in an active state as observed both in vitro in cytotoxic assays and in vivo in a model of virus-induced autoimmune diabetes, the rat insulin promoter-LCMV NP transgenic mouse.

The Src kinases, particularly hck, play an important part in the activation of macrophages and the subsequent production of tumour necrosis factor (TNF)-alpha, interleukin (IL)-1 beta and nitric oxide (NO), leading to the destruction of beta cells which results in the development of diabetes.

|
The infection of DR-BB rats with KRV results in the disruption of the finely tuned immune balance of Th1-like CD45RC+CD4+ and Th2-like CD45RC-CD4+ T cells, leading to the selective activation of beta-cell-cytotoxic effector T cells.

In addition to CD4+ T cells, CD8+ cells and B cells also participate in the pathogenesis.

We used autologous blood monocyte-derived dendritic cells to elicit HLA-A2-restricted CTL to a peptide, MVWESGCTV (aa 797-805), that is contiguous with a dominant CD4 T-cell epitope in the islet antigen tyrosine phosphatase IA-2.

T cell receptor (TCR)-transgenic CD4+ T cells were primed under controlled conditions in vitro before being adoptively transferred into transgenic recipients expressing membrane ovalbumin under the control of the rat insulin promoter (RIP-mOVA).

2520 |
11376339
|
Pathogenicity was associated with T cell production of the macrophage-attracting chemokines CCL3 and CCL4.
|
2521 |
11376339
|
Thus, interactions of lymphocyte function-associated antigen 1 with ICAM-1 during priming induce both qualitative and quantitative alterations in T effector function and induce potentially autodestructive responses.

We previously demonstrated that administration of plasmid DNAs (pDNAs) encoding IL-4 and a fragment of glutamic acid decarboxylase 65 (GAD65) fused to IgGFc induces GAD65-specific Th2 cells and prevents insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice.
|
2523 |
11418698
|
Insulin was chosen based on studies demonstrating that administration of insulin or insulin B chain by a variety of strategies prevents IDDM in NOD mice.
|
2524 |
11418698
|
Surprisingly, young NOD mice receiving i.m. injections of pDNA encoding insulin B chain-IgGFc with or without IL-4 exhibited an accelerated progression of insulitis and developed early diabetes.
|
2525 |
11418698
|
Exacerbation of IDDM correlated with an increased frequency of IFN-gamma-secreting CD4(+) and CD8(+) T cells in response to insulin B chain-specific peptides compared with untreated mice.
|
2526 |
11418698
|
In contrast, treatment with pDNAs encoding insulin A chain-IgGFc and IL-4 elicited a low frequency of IL-4-secreting Th cells and had no effect on the progression of IDDM.
|
2527 |
11418698
|
Vaccination with pDNAs encoding GAD65-IgGFc and IL-4, however, prevented IDDM.
|
2528 |
11418698
|
These results demonstrate that insulin- and GAD65-specific T cell reactivity induced by pDNA vaccination has distinct effects on the progression of IDDM.

At rest and at two hours, counts of white blood cells (WBC), mixed lymphocytes, mature T-cells (CD3), T-helper cells (CD4), T-suppressor/ cytotoxic cells (CD8), B-cells (CD19), natural killer cells (CD16/CD56), and interleukin-2 receptor bearing peripheral blood mononuclear cells (CD25) were measured by flow cytometry.

The aim of the present study was to evaluate the presence of T helper lymphocyte subpopulations: naive (CD4+CD45RA+), memory cells (CD4+CDRO+) and lymphocytes coexpressing both studied phenotypes (CD4+CD45RA+CD45RO+) in subjects at risk of type 1 diabetes (first degree relatives of IDDM patients with autoantibodies) in comparison to age and sex matched controls.
|
2532 |
11450149
|
It could be suggested that CD4+CD45RA+/CD4+CD45RO+ ratio could serve as surrogate marker of diabetes type 1 risk development and presumably for estimation of the efficacy of the preventive procedures in subjects at high risk of IDDM, but further prospective studies are needed.

Both CD4 and CD8 T cells have been shown to be independently capable of beta cell destruction.
|
2536 |
11465949
|
It has previously been shown that the absence of TNF-alpha receptor 1 (p55) on the islets protected islets from CD4 T-cell-mediated destruction as long as the T cells did not have access to wild-type islets in vivo.
|
2537 |
11465949
|
In this study, we demonstrate that islet TNF-alpha receptor 1 (p55) influences the expression of LIGHT (TNFSF-14), a TNF family member with both cytolytic and costimulatory properties, on BDC2.5 T cells and the expression of its receptor HVEM (TNFRSF-14) by islets, indicating a role for LIGHT-HVEM interactions in autoimmune diabetes.

IFN-gamma-mediated Th1 effects play a major role in the pathogenesis of autoimmune diabetes in nonobese diabetic (NOD) mice.
|
2543 |
11466393
|
We analyzed functional responses of CD4(+) T cells from NOD and B6.G7 MHC congenic mice, which share the H2(g7) MHC region but differ in their non-MHC genetic background.
|
2544 |
11466393
|
Despite comparable proliferative responses, NOD CD4(+) T cells had significantly increased IFN-gamma intracellular/extracellular protein and mRNA responses compared with B6.G7 T cells as measured by intracellular cytokine analysis, time resolved fluorometry, and RNase protection assays.
|
2545 |
11466393
|
The increased IFN-gamma production was not due to an increase in the amount of IFN-gamma produced per cell but to an increase in the number of NOD CD4(+) T cells entering the IFN-gamma-producing pathway.
|
2546 |
11466393
|
B6.G7 lymphoid cells demonstrated an absolute decrease in IFN-gamma mRNA, an increase in IL-4 mRNA production, and a significantly decreased IFN-gamma:IL-4 mRNA transcript ratio compared with NOD cells.
|
2547 |
11466393

CD4(+) T cells from C57BL6 mice also showed significantly decreased IFN-gamma production compared with CD4(+) T cells from NOD.H2(b) MHC-congenic mice (which have an H2(b) MHC region introgressed onto an NOD non-MHC background).
|
2548 |
11466393

Therefore, the NOD non-MHC background predisposes to a quantitatively increased IFN-gamma response, independent of MHC class II-mediated T cell repertoire selection, even when compared with a prototypical Th1 strain.

IFN-gamma-mediated Th1 effects play a major role in the pathogenesis of autoimmune diabetes in nonobese diabetic (NOD) mice.
|
2575 |
11466393
|
We analyzed functional responses of CD4(+) T cells from NOD and B6.G7 MHC congenic mice, which share the H2(g7) MHC region but differ in their non-MHC genetic background.
|
2576 |
11466393
|
Despite comparable proliferative responses, NOD CD4(+) T cells had significantly increased IFN-gamma intracellular/extracellular protein and mRNA responses compared with B6.G7 T cells as measured by intracellular cytokine analysis, time resolved fluorometry, and RNase protection assays.
|
2577 |
11466393
|
The increased IFN-gamma production was not due to an increase in the amount of IFN-gamma produced per cell but to an increase in the number of NOD CD4(+) T cells entering the IFN-gamma-producing pathway.
|
2578 |
11466393
|
B6.G7 lymphoid cells demonstrated an absolute decrease in IFN-gamma mRNA, an increase in IL-4 mRNA production, and a significantly decreased IFN-gamma:IL-4 mRNA transcript ratio compared with NOD cells.
|
2579 |
11466393
|
CD4(+) T cells from C57BL6 mice also showed significantly decreased IFN-gamma production compared with CD4(+) T cells from NOD.H2(b) MHC-congenic mice (which have an H2(b) MHC region introgressed onto an NOD non-MHC background).
|
2580 |
11466393
|
Therefore, the NOD non-MHC background predisposes to a quantitatively increased IFN-gamma response, independent of MHC class II-mediated T cell repertoire selection, even when compared with a prototypical Th1 strain.

CD4(+) T cell responses to glutamic acid decarboxylase (GAD65) spontaneously arise in nonobese diabetic (NOD) mice before the onset of insulin-dependent diabetes mellitus (IDDM) and may be critical to the pathogenic process.
|
2582 |
11466400
|
However, since both CD4(+) and CD8(+) T cells are involved in autoimmune diabetes, we sought to determine whether GAD65-specific CD8(+) T cells were also present in prediabetic NOD mice and contribute to IDDM.
|
2583 |
11466400
|
Naive NOD spleen cells stimulated with GAD65 peptides 206-214 (p206) and 546-554 (p546) produced IFN-gamma and showed Ag-specific CTL responses against targets pulsed with homologous peptide.
|
2584 |
11466400
|
Spontaneous CTL responses to p206 and p546 were mediated by CD8(+) T cells that are capable of lysing GAD65-expressing target cells, and p546-specific T cells transferred insulitis to NOD.scid mice.
|
2585 |

|
This report reveals a potential therapeutic role for MHC class I-restricted peptides in treating autoimmune disease and revisits the notion that the CD4- and CD8-inducing determinants on some molecules may benefit from a proximal relationship.

Intra-islet CD4 and CD8 cells and macrophages were also enumerated at day 11.
|
2597 |
11467420
|
In the latter group, CD4 and CD8 cells and macrophages were also higher at day 11 than all other 4 groups (CD4: p < 0.05; CD8: p< 0.05; macrophages: p<0.0001).
|

Intra-islet CD4 and CD8 cells and macrophages were also enumerated at day 11.

The increase of murine interleukin-1 beta when mouse plastic-adherent spleen cells were cultured with PIC (P < 0.04) was indicative of macrophage activation.
|
2601 |
11472422
|
Another mechanism was apparent, since co-incubation of PIC with purified mouse T cells or CD4+ T cells, re-mixed with antigen-presenting cells, led to a decrease (P < 0.01) of insulin release.
|
2602 |
11535635
|
The peripheral nerve tissue was infiltrated with dendritic cells, CD4(+), and CD8(+) T cells.
|
2603 |
11535635
|
This model demonstrates that NOD mice have "cryptic" autoimmune defects that can polarize toward the nervous tissue after the selective disruption of CD28/B7-2 costimulatory pathway.
|
2604 |
11544341
|
IL-15 is a powerful T cell growth factor (TCGF) with particular importance for the maintenance of CD8(+) T cells.
|
2605 |
11544341
|
Because costimulation blockade does not result in universal tolerance, we hypothesized that "escape" from costimulation blockade might represent a CD8(+) and IL-15/IL-15R(+)-dependent process.
|
2606 |
11544341
|
For this analysis, we have used an IL-15 mutant/Fcgamma2a protein, a potentially cytolytic protein that is also a high-affinity receptor site specific antagonist for the IL-15Ralpha receptor protein, as a therapeutic agent.
|
2607 |
11544341
|
The IL-15-related fusion protein was used as monotherapy or in combination with CTLA4/Fc in murine islet allograft models.
|
2608 |
11544341
|
As monotherapies, CTLA4/Fc and an IL-15 mutant/Fcgamma2a were comparably effective in a semiallogeneic model system, and combined treatment with IL-15 mutant/Fcgamma2a plus CTLA4/Fc produced universal permanent engraftment.
|
2609 |
11544341
|
The analysis revealed that the IL-15 mutant/Fc treatment confers partial protection from both CD4(+) and CD8(+) T cell graft infiltration.
|
2610 |
11544341
|
In rejections occurring despite CTLA4/Fc treatment, concomitant treatment with the IL-15 mutant/Fcgamma2a protein blocked a CD8(+) T cell-dominated rejection processes.
|
2611 |
11544341
|
Hence, we have demonstrated that targeting the IL-15/IL-15R pathway represents a new and potent strategy to prevent costimulation blockade-resistant CD8(+) T cell-driven rejection.
|
2612 |

|
To examine these issues, we analyzed TCR Vbeta chain-specific up-regulation of the early T cell activation marker, CD69, on CD4 T cells after incubation with Coxsackievirus B4 (CVB4) Ags.
|
2613 |
11544345
|
Up-regulation of CD69 by different TCR families was significantly more frequent in new onset type 1 DM patients (p = 0.04), 100% of whom (n = 8) showed activation of CD4 T cells bearing Vbeta8, compared with 50% of control subjects (n = 8; p = 0.04).

Here, we completely blocked adoptive transfer of diabetes and reduced spontaneous disease incidence from 71% to 17% by simultaneously administering a combination of antibodies directed against alpha4, beta2, and beta7 integrins and their ligands VCAM-1, MAdCAM-1, and ICAM-1 for 52 and 28 days, respectively.
|
2617 |
11590186
|
CD4 and CD8 T cells and macrophages were excluded from islets and remained entrapped in a peri-islet location as inactive exiles, no longer expressing normal levels of interferon-gamma, interleukin-4, and iNOS.
|
2618 |
11591120
|
In comparison with IRF-1(+/+), the percentage of CD4(+) and Mac-1(+) splenic cells significantly increased, whereas CD3(+), CD8(+) and B220(+) cells decreased in IRF-1(-/-).
|
2619 |
11591120
|
Furthermore, spleen cell proliferation in response to Con A or murine GAD65 peptide, a major autoantigen of the pancreatic beta-cell, significantly increased, and the IFN-gamma/IL-10 ratio in the culture supernatant significantly decreased in IRF-1(-/-), suggesting Th2 deviation in cytokine balance.

|
In this regard, in vitro anti-CD3-mediated stimulation demonstrates impaired activation of lymph node CD4 T cells in muMT(-/-) NOD mice as compared with that of wild-type counterparts, a deficiency that is correlated with an exaggerated CD4 T cell:APC ratio in lymph nodes of muMT(-/-) NOD mice.
|
2621 |
11600216
|
The disease is characterized by loss of tolerance to auto-antigens such as GAD, insulin, and the protein tyrosine phosphatase-like molecule, IA-2.
|
2622 |
11600216
|
We identified T cell epitopes on the intracytoplasmic region of IA-2 by immunizing DQ8/NOD, DQ8/B10, and NOD mice with overlapping 18 mer peptides in CFA.
|
2623 |
11600216
|
We demonstrated MHC class II and CD4 restriction of proliferative responses using appropriate blocking antibodies.

These cells, which express CD4, CD25, and CD62L, develop in the thymus and survive in a CD28-dependent manner in the periphery to maintain the homeostatic equilibrium of immunity and tolerance.
|
2625 |
11723052
|
Importantly, numbers and effector functions of autoaggressive CD4 and CD8 lymphocytes were not decreased in the protected mice, and CTLs were still able to kill syngeneic islet cells in vitro with equal efficacy compared with CTLs from the original RIP-LCMV strain.
|
2626 |
11723051
|
When thymic precursor cells of beta2-microglobulin gene-deficient AKR mice, which have a deficient NKT population, were introduced into NOD.scid recipients, both CD4(+) and CD8(+) T-cell populations developed and the recipient mice developed insulitis and diabetes.

In vitro secretion of interleukin 2 and expression of IL-2 receptor in peripheral blood lymphocytes in high risk of insulin-dependent diabetes mellitus subjects.
|
2628 |
11729828
|
Interleukin 2 (IL-2)--a Th1 lymphocyte-derived cytokine is at present considered to play an important role in the etiopathogenesis of insulin-dependent diabetes mellitus.
|
2629 |
11729828
|
In the previous studies increased, decreased and unchanged IL-2 levels in patients with recent onset of insulin-dependent diabetes mellitus (IDDM) were found.
|
2630 |
11729828
|
The aim of our study was to estimate in vitro secretion of IL-2 and CD25 antigen expression by the peripheral blood T lymphocytes in subjects at the preclinical stage of IDDM (prediabetes), but still without metabolic disturbances.
|
2631 |
11729828
|
In 27 first degree relatives of IDDM patients with antibodies against different pancreatic islet cell antigens (ICA, GADA, IAA, IA-2) CD25 antigen expression on peripheral blood lymphocytes T was measured by flow cytometry and IL-2 concentration in supernatants of 48 and 72 h cultures of peripheral whole blood with 10 microg/ml PHA was estimated by ELISA.
|
2632 |
11729828
|
In the studied high risk IDDM subjects the decreased CD25 expression in peripheral CD4+ lymphocytes T and a negative correlation between the percentage of CD25+ cells and islet cell antibodies (ICA) titres was observed.
|
2633 |
11729828
|
A significant increase of IL-2 secretion at 72 h of PHA stimulation was shown in first degree relatives of IDDM patients with a combination of 3 or more antipancreatic-B cell antibodies.
|
2634 |
11729828
|
The present study suggests the involvement of IL-2 in the pathogenesis of IDDM.

A ligand for the chemokine receptor CCR7 can influence the homeostatic proliferation of CD4 T cells and progression of autoimmunity.
|
2636 |
11739486
|
Although the mechanisms are unknown, we find that the chemokine CCL21 (also known as TCA4, SLC, 6Ckine), a ligand for the chemokine receptor CCR7, can regulate homeostasis of CD4 (but not CD8) T cells.
|
2637 |
11739486
|
In the absence of CCR7 ligands, transferred CD4 T cells failed to expand in lymphopenic hosts, whereas in the presence of CCL21 overexpression, homeostatic CD4 T cell proliferation occurred even in nonlymphopenic recipients.
|
2638 |
11739486
|
These results suggest that CD4 T cells use local concentrations of CCR7 ligands as an index of T cell steady state numbers and that homeostatic expansion of the T cell population may be a contributing factor in the development of autoimmune disease.

T cells clones recognizing insulin, both CD4 and CD8, can transfer disease to young mice or immunodeficient animals.

We also report low numbers of resting CD4(+) CD25(+) T cells in IMD patients, a subset of T cells shown to have important immunoregulatory functions in abrogating autoimmunities in 3-day thymectomized experimental mice.
|
2653 |
11781358
|
Whereas a biased Th1 to Th2 cytokine profile has been suggested to underlie the pathogenesis of IMD in both species, we found defective production of IFN-gamma in our patients after in vitro stimulation of their PBMCs by phorbol-myristate acetate and ionomycin and both IFN-gamma and IL-4 deficiencies in V(alpha)24(+) NK T-enriched cells.
|
2654 |
11785671
|
Although there was no evidence of typical insulitis in early disease development (day 10), in both rats and mice, macrophages, CD4+ and CD8+ cells were present in the islets of Langerhans as diffuse mononuclear infiltrates with the expression of IFN-gamma, and inducible NO synthase (iNOS).
|
2655 |
11793013
|
Data obtained on non-obese diabetic (NOD) mice suggest that macrophages and CD4+ T-cells are the main cellular effectors, whereas CD8+ T-cells are more important initiators of the immune process leading to beta-cell death.
|
2656 |
11793013
|
Perforin could be the effector molecule utilized by CD8+ T-cell initiation, whereas CD4+ mediated beta-cell destruction is mostly dependent on Fas/FasL and the cytokines IFNgamma and TNF-alpha.
|
2657 |
11793013
|
The macrophage cytokine IL-1beta in combination with IFN-gamma and TNF-alpha, plays an important role for beta-cell dysfunction and death.
|
2658 |
11793013
|
Signal transduction by these cytokines involves: (i) binding to specific receptors, (ii) signal transduction by cytosolic kinases (especially the so-called mitogen- and stress-activated protein kinases) and/or phosphatases, (iii) mobilization of diverse transcription factors - with nuclear factor kappaB (NF-kappaB), AP-1 and STAT-1 probably playing key roles for beta-cell apoptosis; (iv) up-regulation or down-regulation of gene transcription.

|
Antidiabetogenic MHC class II molecules may thus afford diabetes resistance by presenting, on dendritic cells and macrophages, tolerogenic peptides to a subset of highly diabetogenic and MHC-promiscuous CD4(+) T-cells that play a critical role in the initiation of diabetes.
|
2665 |
11826762
|
It shares many of these functions with other cytokines such as IL-15, which complicates the interpretation of the IL-2-deficient phenotype.
|
2666 |
11826762
|
The autoimmune phenotype associated with IL-2 deficiency results from the dysregulated activity of thymus-derived TCR alpha beta CD4+ and/or CD8+ T cells.
|
2667 |
11826762
|
The IL-2R signal responsible for maintaining homeostasis is not dependent on either the Shc or Stat5 pathways, therefore AICD, which is Stat5-dependent in vitro, cannot be the critical mechanism.
|
2668 |
11826762
|
Finally, expression of the IL-2R in the thymus and not the periphery appears sufficient to suppress the autoimmune phenotype, suggesting that IL-2 signaling may be required for some aspect of thymocyte selection and/or differentiation that has so far gone undetected.

The antidiabetogenic effects of DEF rely on the induction of anergy in splenic autoreactive CD4+ T cells via alteration of early T cell receptor signaling and stimulation of interleukin 10-secreting T regulatory type 1 cells in the pancreas.

Pancreatic lymph node-derived CD4(+)CD25(+) Treg cells: highly potent regulators of diabetes that require TRANCE-RANK signals.
|
2671 |
11869680
|
Here we show in a CD8(+) T cell-mediated model of type 1 diabetes that CD4(+)CD25(+) Treg cells prevent beta cell destruction following localized inflammation in the islets of Langerhans.
|
2672 |
11869680
|
PLN-derived Treg cells are extremely potent; only 2 x 10(3) cells are needed to prevent diabetes development, and their capacity to regulate is dependent on TNF-related activation induced cytokine-receptor activator of NFkappaB signals.
|
2673 |
11869680
|
Indeed, blockade of this pathway results in decreased frequency of CD4(+)CD25(+) Treg cells in the PLN, resulting in intra-islet differentiation of CD8(+) T cells into CTLs and rapid progression to diabetes.

We report here that CD4(+) and CD4(-)CD8(-) (double negative [DN]) NKT cell subsets represent functionally distinct lineages with marked differences in their profile of cytokine secretion and pattern of expression of chemokine receptors, integrins, and NK receptors.
|
2683 |
11877486

CD4(+) NKT cells were the exclusive producers of interleukin (IL)-4 and IL-13 upon primary stimulation, whereas DN NKT cells had a strict Th1 profile and prominently expressed several NK lineage receptors.

We report here that CD4(+) and CD4(-)CD8(-) (double negative [DN]) NKT cell subsets represent functionally distinct lineages with marked differences in their profile of cytokine secretion and pattern of expression of chemokine receptors, integrins, and NK receptors.
|

|
CD4(+) NKT cells were the exclusive producers of interleukin (IL)-4 and IL-13 upon primary stimulation, whereas DN NKT cells had a strict Th1 profile and prominently expressed several NK lineage receptors.

A new type of antigen presenting molecule (dimeric MHC class-II/peptide, DEF) endowed with antigen-specific immunomodulatory effects such as induction of Th2 polarization and T-cell anergy is also described as a potential antidiabetogenic agent.
|
2687 |

|
According to our preliminary results, the MHC II/peptide-based approach may provide rational grounds for further development of antigen-specific immunotherapeutic agents such as human-like MHC lI/peptide chimeras endowed with efficient down-regulatory effects in CD4 T-cell-mediated autoimmune diseases such as Type 1 diabetes, multiple sclerosis, primary biliary cirrhosis, and rheumatoid arthritis.

To date, no marker for autoimmune T cells has been described, although it was previously demonstrated that autoimmune mice have a large population of CD4(+) cells that express CD40.
|
2695 |

We show that autoimmune diabetes-prone nonobese diabetic mice have high levels of CD40(+)CD4(+) T cells in the thymus, spleen, and importantly, in the pancreas.
|
2696 |

Complexity of human immune response profiles for CD4+ T cell epitopes from the diabetes autoantigen GAD65.
|

We have investigated recognition of the GAD65 protein, one of the well-characterized autoantigens in type I diabetes, among individuals carrying the HLA-DR4 haplotypes characteristic of susceptibility to IDDM.
|

Type 1 diabetes is a chronic progressive autoimmune disease characterized by mononuclear cell infiltration, dominated by interleukin-12 (IL-12)-dependent Th1 cells, of the pancreatic islets, with subsequent destruction of insulin-producing beta-cells.
|
2708 |
11978632
|
Thus, a short treatment of adult NOD mice with an analog of 1,25-dihydroxyvitamin D(3) inhibits IL-12 production, blocks pancreatic infiltration of Th1 cells, enhances CD4(+)CD25(+) regulatory cells, and arrests the progression of type 1 diabetes, suggesting its possible application in the treatment of human autoimmune diabetes.
|
2709 |
11978633
|
T-cell activation defined in flow cytometry by CD4(high) and/or CD25 markers were observed in all type 1 diabetic patients and some at-risk subjects, but not in normal control subjects.

11978635
|
To elucidate the role of Fas/FasL interactions in NOD diabetes, the effects of neutralizing anti-FasL antibody on autoimmune responses were evaluated.
|
2713 |
11978635
|
Islet-specific CD8(+) and CD4(+) T-cells expressed FasL upon activation and mediated FasL-dependent cytotoxicity against Fas-expressing target cells in vitro, although their cytotoxicity against islet cells was not blocked by anti-FasL antibody.
|
2714 |
11978635
|
On the other hand, blockade of Fas/FasL interactions significantly inhibited CD4(+) T-cell-dependent diabetes in adoptive transfer models.

In the direct PLNA, diclofenac also increased the percent of T cells in the PLN with activated phenotypes (CD44(high)CD62L(low) and CD44(high)CD62L(high)).
|
2739 |
11992736
|
Finally, an increase in the intracellular level of IL-4, but not INFgamma, was detected in CD4(+) PLN cells following the injection of diclofenac mixed with TNP-OVA.

We examined the expression of IFN-gamma, a characteristic Th1 cytokine, and IL-4, a characteristic Th2 cytokine, in islet infiltrates of female and male NOD mice at various ages.
|
2741 |
11994496
|
IFN-gamma was significantly higher in young females, whereas IL-4 was higher in young males.
|
2742 |
11994496
|
CD4(+) T cells isolated from lymph nodes of female mice and activated with anti-CD3 and anti-CD28 Abs produced more IFN-gamma, but less IL-4, as compared with males.
|
2743 |
11994496
|
Treatment of CD4(+) T cells with estrogen significantly increased, whereas testosterone treatment decreased the IL-12-induced production of IFN-gamma.
|
2744 |
11994496
|
We then examined whether the change in IL-12-induced IFN-gamma production by treatment with sex hormones was due to the regulation of STAT4 activation.
|
2745 |
11994496
|
We found that estrogen treatment increased the phosphorylation of STAT4 in IL-12-stimulated T cells.
|
2746 |
11994496
|
We conclude that the increased susceptibility of female NOD mice to the development of autoimmune diabetes could be due to the enhancement of the Th1 immune response through the increase of IL-12-induced STAT4 activation by estrogen.

|
Similarly, the dramatic decreases in the size of the CD4(+)CD8(+) population of cells in the thymus and in the number of thymocytes in the S and G2/M phases of the cell cycle observed in wild-type mice administered PPs were much less extensive in PPARalpha-null mice.

Flow cytometric analyses found that autoreactive T-cell lines from patients induced by beta-cell antigens consisted of four major subsets (CD4(+)CD56(-), CD4(+)CD56(+), CD8(+)CD56(-), and CD8(+)CD56(+)) and that CD56(+) NKT cells might be derived from CD56(-) T cells.
|
2757 |
12039407
|
Moreover, the proportion of CD56(+) NKT cells in the T-cell lines was influenced by time course of repeated antigen stimulation. beta-cell antigen-specific CD56(+) NKT (CD4(+) or CD8(+)) cells were more aggressive (HLA-restricted and -unrestricted) effector cells lysing target cells such as K562, Jurkat, P815 plus anti-CD3 antibody, and autologous B cells sensitized by beta-cell peptides, when compared with their CD56(-) counterparts. beta-cell antigen- specific CD4(+)CD56(+) NKT cells showed non-HLA-restricted cytotoxicity to human beta cells, insulinoma cell line CM, and to islet cell lines TRM-6 and HP62 expressing CD56 but not to four CD56(-) pancreatic cell lines of non- islet origin.
|
2758 |
12039407

The CD4(+)CD56(+) NKT cells showed stronger cytotoxicity to CM, TRM-6 and HP62 cells than did CD4(+)CD56(-) T cells.

We followed the fate of K(d)- or I-A(g7)-restricted beta cell-autoreactive T cells in monoclonal TCR-transgenic NOD mice expressing or lacking CD154. 8.3-NOD.RAG-2(-/-)/CD154(-/-) mice, which bear autoreactive CD8(+) T cells, developed diabetes with the same incidence and tempo as 8.3-NOD.RAG-2(-/-)/CD154(+) mice.

Recruitment of CD154(-/-) 8.3-CD8(+) CTL was accelerated by CD154(+)CD4(+) T cells, by expression of a B7.1 transgene in beta cells or by treatment of the mice with CpG-DNA or an agonistic anti-CD40 antibody.
|
2775 |
12049723
|
In contrast, the autoreactive CD4(+) T cells maturing in 4.1-NOD.RAG-2(-/-) mice lost their diabetogenic potential if they lacked CD154, even in the presence of CD154(+)CD4(+) T cells, B7.1 molecules on beta cells, CpG-DNA treatment, or systemic CD40 ligation.

Multiple roles for tumor necrosis factor-alpha and lymphotoxin alpha/beta in immunity and autoimmunity.
|
2805 |
12110133
|
In several experimental systems (Jurkat T cells, murine T-cell hybridomas), TNF-alpha appears to cause a downregulation of signaling through the TCR, revealed by changes in calcium flux, activation of p21, p23 and ZAP70, and a decrease in nuclear activation of NF-kappaB.
|
2806 |
12110133
|
The paradoxical effects of neonatal TNF-alpha administration in NOD mice in increasing incidence of and hastening onset of type 1 diabetes, while neonatal anti-TNF administration completely prevents all signs of islet cell autoimmunity, are due partly to the low levels of CD4+CD25+ T cells in NOD mice.
|
2807 |
12110133
|
In contrast, neonatal administration of anti-TNF-alpha results in a dramatic increase in the levels of CD4+CD25+ regulatory T cells, to levels beyond those seen in wild-type untreated NOD mice.
|
2808 |
12110133

TNF-alpha and LTalpha/beta thus have pleomorphic regulatory effects on the development and expression of autoimmunity.

We previously demonstrated that immunotherapy with dendritic cells (DC) prevented diabetes development in prediabetic NOD mice and that this effect was optimal when using a stimulatory DC population generated from bone marrow cells cultured with granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-4.
|
2815 |
12115623
|
In this study, we have investigated the mechanism by which GM-CSF- and IL-4-cultured DC prevent diabetes in prediabetic NOD mice.

Furthermore, sorted CD45RB(lo) CD25+ CD4+ T cells from the spleen of DC-treated mice produced high amounts of Th2 cytokines following anti-TCR stimulation, suggesting that these cells are responsible for the apparent Th2 shift.

Furthermore, combined blockade of the CD28/B7 and CD154/CD40 costimulatory pathways induces tolerance in multiple CD4+ T-cell dependent allograft models.
|
2818 |
12118894
|
Analysis of the costimulatory capacity of different antigen presenting cell (APC) populations demonstrated that APCs resident within the donor skin, Langerhans cells, are potent stimulators not requiring CD28- or CD154-dependent costimulation for direct major histocompatibility complex (MHC) antigen presentation.
|
2819 |
12118894
|
These results complement previous work examining the role of costimulation on CD8+ T cells, supporting a model in which the effectiveness of costimulatory blockade in the setting of transplantation may be selective for the indirect pathway of MHC alloantigen presentation.

CC chemokine receptor 5 (CCR5) is expressed preferentially by CD4(+) T helper 1 (Th1) cells.

2821 |
12145162
|
In CCR5(-/-) mice, intragraft mRNA expression of interleukin-4 and -5 was increased, whereas that of interferon-gamma was decreased, corresponding to a Th2 pattern of T-cell activation in the target tissues compared with a Th1 pattern observed in controls.

|
In addition, anti-CD45RB treatment led to reduced expression of LFA-1 and CD62 ligand (CD62L) on CD4 T cells, independent of antigenic challenge.
|
2823 |

LFA-1 may enhance co-stimulation, and both LFA-1 and CD62L are involved in T cell trafficking.

In parallel, the proliferative response of CD4+ T-cells to the primary protein antigens keyhole limpet hemocyanin (KLH) and sperm whale myoglobin (SWM) was measured in vitro using monocyte-derived dendritic cells (MDDC) as antigen-presenting cells.
|
2829 |

CD4+CD25+ T cells have been implicated as mediators of self-tolerance.
|
2903 |
12221281
|
We show (i) NOD mice have a relative deficiency of CD4+CD25+ T cells in thymus and spleen; (ii) administration of TNF or anti-TNF to NOD mice can modulate levels of this population consistent with their observed differential age-dependent effects on diabetes in the NOD mouse; (iii) CD4+CD25+ T cells from NOD mice treated neonatally with TNF show compromised effector function in a transfer system, whereas those treated neonatally with anti-TNF show no alteration in ability to prevent diabetes; and (iv) repeated injection of CD4+CD25+ T cells into neonatal NOD mice delays diabetes onset for as long as supplementation occurred.
|
2904 |
12221281
|
These data suggest that alterations in the number and function of CD4+CD25+ T cells may be one mechanism by which TNF and anti-TNF modulate type I diabetes mellitus in NOD mice.

No preferential inactivation was shown in freshly sorted CD4+, CD8+, CD19+ cells or in IL-2 cultured CD4 and CD8 T cells, indicating that peripheral blood lymphocytes in these women are randomly selected.
|
2907 |

Fas and Fas ligand immunolocalization in pancreatic islets of NOD mice during spontaneous and cyclophosphamide-accelerated diabetes.
|
2911 |
12365794
|
Here, dual-label immunohistochemistry was employed to examine the intra-islet expression, distribution and cellular sources of Fas and FasL in the NOD mouse, during spontaneous diabetes (days 21, 40 and 90) and following acceleration of diabetes with cyclophosphamide (days 0, 4, 7, 11 and 14 after cyclophosphamide administration).
|
2912 |
12365794
|
FasL was expressed constitutively in most beta cells but not in glucagon or somatostatin cells or islet inflammatory cells and paralleled the loss of insulin immunolabelling with advancing disease.
|
2913 |
12365794
|
During spontaneous and cyclophosphamide diabetes, it was observed in a higher proportion of islet infiltrating macrophages than CD4 and CD8 T cells, concomitant with advancing insulitis.
|
2914 |
12365794
|
In cyclophosphamide-treated mice, the proportion of Fas-positive intra-islet CD4 and CD8 T cells at day 14 (with and without diabetes) was considerably higher than at days 0, 4, 7 and 11.
|
2915 |
12365794
|
Our results show constitutive expression of FasL in beta cells in the NOD mouse and predominant expression of Fas in intra-islet macrophages and to a lesser extent in T cells prior to diabetes onset.
|
2916 |
12365794
|
Interleukin-1beta in intra-islet macrophages may induce Fas and inducible nitric oxide synthase expression in an autocrine and paracrine manner and mediate beta cell destruction or even death of some macrophages and T cells.

Protection induced by CTB-insulin was transferred to naive recipients by splenic CD4+ T cells.
|
2925 |
12390307
|
Reverse transcription-polymerase chain reaction analysis of recipients' pancreatic glands revealed an increase of TGF-beta and IL-10 transcripts after donor mice tolerization, while levels of IFN-gamma and IL-4 RNAs were unchanged.
|
2926 |
12390307

CD4-dependent generation of dominant transplantation tolerance induced by simultaneous perturbation of CD154 and LFA-1 pathways.
|
2928 |
12391193
|
CD154 and LFA-1 (CD11a) represent conceptually distinct pathways of receptor/ligand interactions (costimulation and adhesion/homing, respectively) that have been effectively targeted to induce long-term allograft acceptance and tolerance.
|
2929 |
12391193
|
In vitro analysis indicated that simultaneous targeting of CD154 and LFA-1 resulted in profound inhibition of alloreactivity, suggesting that combined anti-CD154/anti-LFA-1 therapy could be highly effective in vivo.
|
2930 |
12391193
|
Thus, we evaluated combining mAb therapies targeting CD154 and LFA-1 for inducing transplantation tolerance to pancreatic islet allografts.
|
2931 |
12391193
|
Therefore, simultaneous perturbation of CD154 and LFA-1 molecules can result in profound tolerance induction not accomplished through individual monotherapy approaches.
|
2932 |
12401711
|
We also found that the tendency of NOD mice to resist tolerance induction by costimulation blockade is mediated by both CD4+ and CD8+ T-cells, not directly linked to the presence of autoimmunity, and conferred by non-MHC background genes.
|
2933 |

|
Diabetes was characterized by diffuse CD4(+)CD8(+) T-cell infiltration of pancreatic islets and severe insulin deficiency, and ppIns, proinsulin, and insulin DNA were equally effective for disease induction.

Insulin, phogrin and phogrin-peptide 7 (aa 755-777) but not phogrin-peptide 2 (aa 640-659) or tetanus toxin peptide were recognized as antigens.
|
2935 |

|
2943 |
12426635
|
Cytokines produced by islet-infiltrating mononuclear cells may be directly cytotoxic and can be involved in islet destruction coordinated by CD4+ and CD8+ cells.
|
2944 |
12426635
|
We utilized a semiquantitative RT-PCR assay to analyze in vitro the mRNA expression of TNF-alpha and IFN-gamma cytokine genes in isolated islets (N = 100) and spleen cells (5 x 10(5) cells) from female NOD mice during the development of diabetes and from female CBA-j mice as a related control strain that does not develop diabetes.
|
2945 |
12426635
|
An increase in IFN-gamma expression in islets was observed for females aged 28 weeks (149 +/- 29 arbitrary units (AU), P<0.05, Student t-test) with advanced destructive insulitis when compared with CBA-j mice, while TNF-alpha was expressed in both NOD and CBA-j female islets at the same level at all ages studied.
|
2946 |
12426635
|
The data suggest that IFN-gamma and TNF-alpha expression in pancreatic islets of female NOD mice is associated with beta cell destruction and overt diabetes.

Moreover, the increased IFN-gamma:IL-4 cytokine ratio was independent of the genetic background of APCs, since NOD CD4(+) T cells generated increased IFN-gamma and decreased IL-4 compared with B6.G7 CD4(+) T cells, regardless of whether they were stimulated with NOD or B6.G7 APCs.
|
2954 |
12444170
|
Cell cycle analysis showed that the cytokine differences were not due to cycle/proliferative differences between NOD and B6.G7, since stimulated CD4(+) T cells from both strains showed quantitatively identical entry into subsequent cell divisions (shown by CFSE staining), although NOD cells showed greater numbers of IFN-gamma-positive cells with each subsequent cell division.
|
2955 |
12444170
|
Moreover, 7-aminoactinomycin D and 5-bromo-2'-deoxyuridine analysis showed indistinguishable entry into G(0)/G(1), S, and G(2)/M phases of the cell cycle for both NOD and B6.G7 CD4(+) cells, with both strains generating IFN-gamma predominantly in the S phase.

CCR4 was found exclusively on memory CD4(+) T cells during the progression of disease in NOD mice.

Cells expressing the CCR4 ligand TARC (thymus- and activation-regulated chemokine) were detected within infiltrated islets from prediabetic mice.

Interestingly, neutralization of macrophage-derived chemokine (MDC) with Ab caused a significant reduction of CCR4-positive T cells within the pancreatic infiltrates and inhibited the development of insulitis and diabetes.

These observations were further confirmed by the results of CD4(+) enzyme-linked immunospot assay for interferon (IFN)-gamma and interleukin (IL)-4 and intracellular cytokine staining of IFN-gamma producing CD8(+) cells.

Dendritic cells (DCs) not only induce but also modulate T cell activation. 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] induces DCs with a tolerogenic phenotype, characterized by decreased expression of CD40, CD80, and CD86 costimulatory molecules, low IL-12 and enhanced IL-10 secretion.

The enhancement of CD4(+)CD25(+) regulatory T cells, able to mediate transplantation tolerance and to arrest type 1 diabetes development by a short oral treatment with VDR ligands, suggests possible clinical applications of this approach.

FcR-binding "classical" anti-CD3 mAb is a potent immunosuppressive drug that alters CD4(+) and CD8(+) T cell function in vivo via anergy induction and programmed cell death (PCD).
|
3016 |
12538715
|
Anti-CD3-mediated PCD was Fas independent but was mediated by the mitochondria-initiated apoptosis that was abrogated in Bcl-x(L)-transgenic T cells.
|
3017 |
12538715
|
The PCD was more pronounced in CD28-deficient mice consistent with defective Bcl-x(L) up-regulation.
|
3018 |
12538715
|
Residual T cells isolated from anti-CD3-treated wild-type, CD28(-/-), and Bcl-x(L)-transgenic mice were hyporesponsive.
|
3019 |
12538715
|
The hyporesponsiveness was more pronounced in CD28(-/-) and wild-type mice treated with anti-B7-2, suggesting that CD28 interaction with B7-2 regulates T cell responsiveness in anti-CD3-treated animals.

Specifically, and contrary to published reports, the thymocyte subset distribution, the rate and composition of thymic export, and the composition of the peripheral T-cell pool, including the proportion of CD25(+)CD4(+) T-cells, are essentially normal in prediabetic NOD mice.

Accelerated diabetes in rat insulin promoter-tumor necrosis factor-alpha transgenic nonobese diabetic mice lacking major histocompatibility class II molecules.
|
3022 |
12540606
|
Surprisingly, although diabetes was evident in the F1 intercross expressing rat insulin promoter (RIP)-TNF, offspring lacking either endogenous or transgenic class II molecules developed accelerated diabetes with high frequency in both sexes.
|
3023 |
12540606
|
Thus, neonatal expression of TNF-alpha in an islet-specific manner bypassed the requirement of CD4(+) T-cells and resulted in diabetes that could be mediated by CD8(+) T-cells.
|
3024 |
12559622
|
We found that the myocardium of these patients was infiltrated by CD4(+) and CD8(+) T lymphocytes as well as macrophages.
|
3025 |
12559622
|
Finally, mRNA for interleukin-1beta, interferon-gamma, and tumor necrosis factor-alpha was detected in the cardiac specimens, although at a lower level compared with specimens from hearts without signs of viral infections.

Recent data indicate that transforming growth factor-beta-dependent CD4+CD25+ regulatory T cells might have a central role in this effect.

In a trial of an FcR nonbinding humanized anti-CD3 mAb hOKT3gamma1(Ala-Ala) for treatment of patients with type 1 diabetes, we found significant increases in IL-10 and IL-5 in the serum of 63% and 72% of patients, respectively, and TNF-alpha and IL-6 levels that were lower than those previously reported following OKT3 therapy.
|
3028 |
12569167
|
However, the production of IL-10, compared to IFN-gamma on a molar basis, was greater after culture with hOKT3gamma1(Ala-Ala) than with OKT3.
|
3029 |
12569167
|
Flow cytometric studies confirmed that OKT3 induced IFN-gamma and IL-10 production, but hOKT3gamma1(Ala-Ala) induced only detectable IL-10 production in CD45RO(+) cells.
|
3030 |
12569167
|
Moreover, in vivo, we found IL-10(+)CD4(+) T cells after drug treatment.
|
3031 |
12569167
|
These cells were heterogeneous but generally CD45RO(+), CTLA-4(-), and expressed CCR4.
|
3032 |
12574341
|
This hyperactivation was detected for different NF-kappaB complexes and correlated with increased IkappaBalpha degradation.
|
3033 |
12574341
|
Furthermore, increased NF-kappaB activation resulted in an enhanced capacity of NOD vs NOR or BALB/c Mphi to secrete IL-12(p70), TNF-alpha, and IL-1alpha, which was inhibited upon infection with an adenoviral recombinant encoding a modified form of IkappaBalpha.
|
3034 |
12574341
|
In contrast, elevated NF-kappaB activation had no significant effect on the capacity of NOD Mphi to stimulate CD4(+) or CD8(+) T cells in an Ag-specific manner.
|

Skewing their cytokine production from a Th1 (primarily IFN-gamma) to a Th2 (primarily IL-4 and IL-10) pattern is a widely proposed approach to dampen the pathogenicity of autoreactive diabetogenic T cells.
|
3036 |
12594305
|
Murine CD4 T cells are characterized by a reciprocal relationship between the production of IFN-gamma and expression of the beta-chain component of its receptor (IFN-gamma RB).
|
3037 |
12594305
|
Thus, NOD mice constitutively expressing a CD2 promoter-driven IFN-gamma RB transgene in all T cells are Th1-deficient.
|
3038 |
12604308
|
We report that insulin promoter murine CD80 (RIP-CD80) transgenic mice are extraordinarily susceptible to autoantigen-induced diabetes, while spontaneous disease is rare.
|
3039 |
12604308
|
While both RIP-GP(+)and RIP-CD80(+)GP(+)mice mounted moderate CD4-independent CTL responses, only CD80(+)GP(+)mice developed severe insulitis and diabetes due to islet-infiltration of activated, gp33-specific, CD8(+)T cells.
|
3040 |
12604308
|
We conclude that aberrant CD80-expression in a peripheral tissue disrupts that tissue's natural resistance to CD8 T cell-mediated autoimmune destruction.
|

We have recently reported that in patients with anti-glutamic acid decarboxylase (GAD) 65(+)diabetes with residual beta-cell function, most with a 'high-titer' (>10U/ml) required insulin within 5 years, whereas most with a 'low-titer' (1.3-9.9U/ml) did not need insulin for over 15-20 years after the onset.
|
3042 |
12604315
|
Although GAD65-reactive CD4(+)cells in the periphery were detected in both groups, a significant positive correlation between serum IP-10 level and the number of GAD65-reactive CD4(+)cells was observed only in the high-titer group.
|
3043 |
12604315
|
Therefore, it has been speculated that the co-existence of GAD65-reactive IFN-gamma-producing CD4(+)cells and a high serum IP-10 level may be important for rapid disease progression as seen in the high-titer group.

Taken collectively, these results indicated that CD4 T cells play a crucial role in T1DM as a source of CD154, and that the role of CD154 on CD4 T cells in insulitis may not be just to facilitate priming and expanding of auto-reactive CD8 T cells by activating antigen-presenting cells bearing islet antigens.

3065 |

Both viruses induced similar humoral and cellular immune responses in the host, but only RV also caused a decrease in splenic CD4(+)CD25(+) T cells in both BBDR rats and normal WF rats.
|
3066 |

|
Surprisingly, RV infection increased CD4(+)CD25(+) T cells in pancreatic lymph nodes of BBDR but not WF rats.
|
3067 |
12646622

This increase appeared to be due to the accumulation of nonproliferating CD4(+)CD25(+) T cells.

The results imply that the reduction in splenic CD4(+)CD25(+) cells observed in RV-infected animals is virus specific, whereas the increase in pancreatic lymph node CD4(+)CD25(+) cells is both virus and rat strain specific.

More generally, the results suggest a mechanism that could link an underlying genetic predisposition to environmental perturbation and transform a "regulated predisposition" into autoimmune diabetes, namely, failure to maintain regulatory CD4(+)CD25(+) T cell function.

This clone proliferates and produces IFNgamma in response to GAD(65) presenting APCs and kills GAD(65) presenting targets.

Furthermore, it expresses TNFalpha, CD25, CD28, CD44, CD45 and LFA1, but not CD95L This is the first example of a GAD(65)specific CD8(+) T cell clone that accelerates the onset of the insulitis, although it does not appear to accelerate the onset of diabetes.

Preceding the clinical diagnosis of type I DM is a preclinical stage characterized by autoantibodies to insulin, glutamic acid decarboxylase (GAD) and a tyrosine phosphatase-like molecule (IA-2).

In contrast, the progression to clinical disease appears associated with class I alleles A24, A30 and B18 while A1, A28, B14 and B56 appear negatively associated.
|
3115 |
12694582
|
These results are consistent with the view that CD4+ T cells responding to peptides in the context of class 2 molecules are responsible for initiating autoantibody production, while the destruction of islet cells leading to clinical expression of the disease is the function of CD8+ T cells recognizing relevant peptides in the context of class I molecules.

To investigate whether TGZ acts by affecting the ICAM-1/LFA-1 pathway and/or the Th1/Th2 cytokine balance in NOD mice, we analysed the IL-1beta-induced ICAM-1 expression on islet-cells and the LFA-1, CD25, IL-2, IFN-gamma, IL-4, and IL-10 expression on splenocytes.
|
3120 |
12711326

Dendritic cells (DCs) not only induce but also modulate T cell activation. 1,25-Dihydroxyvitamin D(3) [1,25-(OH)(2)D(3)] induces DCs with a tolerogenic phenotype, characterized by decreased expression of CD40, CD80, and CD86 co-stimulatory molecules, low IL-12, and enhanced IL-10 secretion.

CD4(+)CD25(+) cells that are able to inhibit the T cell response to a pancreatic autoantigen and to significantly delay disease transfer by pathogenic CD4(+)CD25(-) cells are also induced by treatment of adult nonobese diabetic (NOD) mice with a selected vitamin D receptor (VDR) ligand.

Here we show that proinsulin B24-C36 peptide binds to I-A(g7), the MHC class II molecule of the NOD mouse, and, after intranasal administration, induces regulatory CD4(+) T cells that, in the absence of CD8(+) T cells, block the adoptive transfer of diabetes.
|
3135 |
12727928
|
We then determined that B24-C36, and its core sequence B25-C34, bind to K(d), the NOD mouse MHC class I molecule, and elicit CD8(+) CTLs.
|
3136 |
12727928
|
When the CD8(+) T lymphocyte epitope was truncated at the C34 valine anchor residue for binding to K(d), the residual CD4(+) T cell epitope, B24-C32/33, significantly inhibited diabetes development after a single intranasal dose.

12742378
|
In order to further investigate possible mechanisms underlying this impairment, several factors known to be involved in the down-regulation of the immune response both at the level of APCs and CD4(+) T-cells were investigated: Monocyte-derived dendritic cells (MDDC) from IDDM patients were shown to express elevated amounts of CD86 (B7.2) (p=0.003) and reduced amounts of the adhesion molecule CD54 (ICAM-1) (p=0.03) on their cell surface compared to age-matched healthy controls and patients with non-insulin-dependent diabetes mellitus (NIDDM) as well as decreased SDS-PAGE stability of HLA-DQ and -DR peptide complexes directly isolated from the IDDM patients' peripheral blood mononuclear cells (PBMCs).

3142 |
12742378

Expression of CTLA-4 (CD152), known to be involved in the down-regulation of the immune response, was shown to be increased on CD4(+) T-cells from IDDM patients after exposure to the primary antigen KLH (keyhole limpet hemocyanin) presented by MDDC (p=0.0047).
|
3143 |
12742378

Likewise, purified CD4(+) T-cells from IDDM patients produced elevated levels of the cytokine TGF-beta1 after stimulation with immobilized monoclonal antibodies directed against CD3 and CD28 (p=0.014).

3144 |
12742378

When monocytes from IDDM patients were stimulated with lipopolysaccharide (LPS), an increased tendency to produce the inhibitory cytokine interleukin (IL)-10 (p=0.007) and the acute phase cytokine IL-6 (p=0.044) was observed, whereas the concentrations of tumor necrosis factor (TNF)-alpha, IL-1beta, and IL-12 were comparable to controls.

Our results suggest that HCV-LPs can induce humoral and cellular immune responses that are protective in a surrogate HCV challenge model and that a strong cellular immunity provided by both CD4 and CD8 effector lymphocytes may be important for protection from HCV infection.

IL-12 administration accelerates autoimmune diabetes in both wild-type and IFN-gamma-deficient nonobese diabetic mice, revealing pathogenic and protective effects of IL-12-induced IFN-gamma.

IL-12 administration to nonobese diabetic (NOD) mice induces IFN-gamma-secreting type 1 T cells and high circulating IFN-gamma levels and accelerates insulin-dependent diabetes mellitus (IDDM).
|
3168 |
12759426
|
Here we show that IL-12-induced IFN-gamma production is dispensable for diabetes acceleration, because exogenous IL-12 could enhance IDDM development in IFN-gamma-deficient as well as in IFN-gamma-sufficient NOD mice.
|
3169 |
12759426
|
Both in IFN-gamma(+/-) and IFN-gamma(-/-) NOD mice, IL-12 administration generates a massive and destructive insulitis characterized by T cells, macrophages, and CD11c(+) dendritic cells, and increases the number of pancreatic CD4(+) cells secreting IL-2 and TNF-alpha.

Surprisingly, IL-12-induced IFN-gamma hinders pancreatic B cell infiltration and inhibits the capacity of APCs to activate T cells.
|
3171 |
12759426
|
Although pancreatic CD4(+) T cells from IL-12-treated IFN-gamma(-/-) mice fail to up-regulate the P-selectin ligand, suggesting that their entry into the pancreas may be impaired, T cell expansion is favored in these mice compared with IL-12-treated IFN-gamma(+/-) mice because IL-12 administration in the absence of IFN-gamma leads to enhanced cell proliferation and reduced T cell apoptosis.

NO, an effector molecule in beta cell destruction, is produced ex vivo in high quantity by pancreas-infiltrating cells through a mechanism involving IL-12-induced IFN-gamma.

Conversely, in IL-12-treated IFN-gamma-deficient mice, other pathways of beta cell death appear to be increased, as indicated by the up-regulated expression of Fas ligand on Th1 cells in the absence of IFN-gamma.
|
3174 |
12759426

These data demonstrate that IFN-gamma has a dual role, pathogenic and protective, in IDDM development, and its deletion allows IL-12 to establish alternative pathways leading to diabetes acceleration.

Clinically, IPEX manifests most commonly with diarrhea, insulin-dependent diabetes mellitus, thyroid disorders, and eczema.
|
3210 |
12819471

FOXP3, the gene responsible for IPEX, maps to chromosome Xp11.23-Xq13.3 and encodes a putative DNA-binding protein of the forkhead family.
|
3211 |
12819471

Recent data indicate that FOXP3 is expressed primarily in the CD4+CD25+ regulatory T-cell subset, where it may function as a transcriptional repressor and key modulator of regulatory T-cell fate and function.

The strong associations between poor vitamin D nutrition, particular VDR alleles, and susceptibility to chronic mycobacterial infections, together with evidence that 1alpha,25-(OH)2D3 served as a vaccine adjuvant enhancing antibody-mediated immunity, suggest a model wherein high levels of 1alpha,25-(OH)2D3-liganded VDR transcriptional activity may promote the CD4+ T helper 2 (Th2) cell-mediated and mucosal antibody responses to cutaneous antigens in vivo.

Critical roles of CD30/CD30L interactions in murine autoimmune diabetes.
|
3242 |
12930356
|
CD30/CD30L is a member of tumour necrosis factor (TNF) receptor/TNF superfamily and has been implicated in immune-regulation.
|
3243 |
12930356
|
In this study, we investigated the involvement of CD30/CD30L in the development of diabetes in NOD mice.
|
3244 |
12930356
|
Flow cytometric analysis showed that CD30 and CD30L were highly expressed on CD4+ or CD8+ T cells in the spleen and pancreatic lymph node of younger NOD mice.
|
3245 |
12930356
|
In addition, islet-specific CD4+ or CD8+ T cell lines expressed CD30 and CD30L.
|
3246 |
12930356
|
In addition, the treatment with anti-CD30L mAb also inhibited the development of diabetes induced by adoptive transfer of spleen cells from diabetic NOD mice or islet-specific CD4+ or CD8+ T cell lines into NOD-SCID mice.
|
3247 |
12930356

Transgenic expression of tumor necrosis factor alpha from birth to 25 days of age in the islets of B6 mice that constitutively express CD80 on their beta cells results in accumulation of CD4+CD25+TGF-beta+ cells exclusively in the islets and pancreatic lymph nodes, which delays diabetes progression.
|
3275 |
12949259

In contrast, expression of tumor necrosis factor alpha until 28 days of age prevents islet accumulation of CD4+CD25+TGF-beta+ Treg cells, resulting in acceleration to diabetes.
|
3276 |
12949259

CD4+CD25+ regulatory T (TR) cells have been described in both humans and mice.
|
3360 |
14597769
|
Recently, the forkhead/winged helix transcription factor, FoxP3, has been shown to be important for the function of TR cells in mice.
|
3361 |
14597769
|
In this study, human TR cells were examined and, in results similar to those of studies done in mice, expression of FoxP3 was found exclusively in CD4+CD25+ T cells and correlated with the suppressive activity of these cells.
|
3362 |
14597769
|
In contrast to the mouse studies, activation of human CD4+CD25- T cells led to expression of FoxP3.
|

14597769
|
Thus, in humans, during activation of CD4+CD25- T cells in an immune response, two populations of cells may arise, effector CD4+CD25+ and regulatory CD4+CD25+ T cells, with expression of FoxP3 correlated with regulatory activity.

Naso-respirtory insulin (which avoids insulin degradation) induces CD8+ alpha(alpha) TCR gamma(delta) T(reg) whereas peptides that bind to the NOD MHC class II molecule, I-Ag7, insulin B9-23 and proinsulin B24-C36, induce CD4+ T(regs) Following naso-respiratory delivery of insulin to NOD mice increased numbers of CD8+ gamma(delta) T cells expressing interleukin (IL)10 are detected in the pancreatic lymph nodes.
|
3485 |
14609216
|
CD8+ gamma(delta) T(reg) are conceivably physiological and insulin-specific, induced by exposure to insulin in maternal milk.

In several autoimmune models, feedback regulation employing both CD4+ and CD8+ T cells of TCR specificity can be shown to occur and to account for remission from the transient disease state, or for its prevention.

In this model, the acetylated 1-9 N-terminal antigenic determinant from myelin basic protein (MBP) induces a transient paralytic disease owing to the activation of self-directed, high-affinity, CD4+ T cells.
|
3488 |
14609218
|
A CD4+ T cell directed against a TCR determinant in the framework region of the Vbeta chain, and a CD8+ T cell directed against an upstream, distinct framework determinant, both of which are necessary for regulation, bring about a reversal of the disease process.

CD4+ lymphocytes with specificity for insulin can be induced by immunization with the insulin B chain via the oral route or by DNA vaccination.
|
3496 |
14609223
|
In comparison to non-regulatory insulin B-specific cell lines, they produce high amounts of interleukin (IL)4 and IL10, whereas interferon (IFN)gamma and tumour necrosis factor (TNF)alpha levels are comparable.
|
3497 |
14609223
|
We propose that this is achieved by modulation of antigen presenting cells that lose the ability to propagate aggressive responses after exposure to IL4 or IL10 in vitro.
|
3498 |
14609223
|
In order to avoid induction of insulin B-specific autoaggressive T cells we have demonstrated that administration of IL4 or IL10 at the time of immunization is beneficial and therefore should be part of a potential future clinical application.

Our studies of the mechanism of the non-FcR binding anti-CD3 MAb indicate that the MAb delivers an activation signal to T cells resulting in disproportionate production of interleukin-10 (IL-10) relative to interferon-gamma(IFN-gamma) in vitro compared with FcR binding anti-CD3 MAb, and detectable levels of IL-10, IL-5, but rarely IFN-gamma or IL-2 in the serum after treatment.

We have shown recently that PPARgamma agonists inhibit EAE by blocking IL-12 production, IL-12 signaling, and neural Ag-induced Th1 differentiation.
|
3524 |
14634082
|
The exacerbation of EAE in PPARgamma(+/-) mice associates with an increased expansion of CD4(+) and CD8(+) T cells and expression of CD40 and MHC class II molecules in response to MOGp35-55 Ag.

Systemic and pancreatic cytokine profiles deviated to a Th1-dominant state, and the the frequency of glutamic acid decarboxylase-reactive IFN-gamma-producing CD4(+) cells was also high in the IL-18 group.
|
3526 |
14634096
|
Moreover, it was suggested that the promoting effect of IL-18 might be associated with increased peripheral IL-12, CD86, and pancreatic IFN-inducible protein-10 mRNA expression levels.

|
RIP-E19 expression inhibited MHC class I transport exclusively in beta cells and rendered these cells resistant to lysis by CD8(+) (but not CD4(+)) T cells, both in vitro and in vivo.

It is not clear, however, whether a given subset, notably CD4+CD25+ regulatory T cells, protects from a wide spectrum of immune disorders, or whether specialized subsets of regulatory T cells control each given disease or group of diseases.

The IDDM and NIDDM patients had above-normal absolute lymphocyte counts, whereas the percentages of CD3, CD4 adn CD8 T lymphocytes were significantly reduced.

The low intracellular reduced glutathione(GSH) and the unbalanced profile of key enzymes involved in GSH metabolism, gamma-glutamyltransferase (gamma-GT) and glutathione-S-transferase (GST), account for the increased oxidative status of PBMC from diabetic patients.

MHC class II molecules play a role in the selection of autoreactive class I-restricted CD8 T cells that are essential contributors to type 1 diabetes development in nonobese diabetic mice.
|
3600 |
14707058
|
Development of autoreactive CD4 T cells contributing to type 1 diabetes (T1D) in both humans and nonobese diabetic (NOD) mice is either promoted or dominantly inhibited by particular MHC class II variants.
|
3601 |
14707058
|
In addition, it is now clear that when co-expressed with other susceptibility genes, some common MHC class I variants aberrantly mediate autoreactive CD8 T cell responses also essential to T1D development.
|
3602 |
14707058
|
However, it was unknown whether the development of diabetogenic CD8 T cells could also be dominantly inhibited by particular MHC variants.
|
3603 |
14707058
|
We addressed this issue by crossing NOD mice transgenically expressing the TCR from the diabetogenic CD8 T cell clone AI4 with NOD stocks congenic for MHC haplotypes that dominantly inhibit T1D.
|
3604 |
14707058
|
In contrast, heterozygous expression of some MHC haplotypes conferring T1D resistance anergized AI4 T cells through decreased TCR (H2(b)) or CD8 expression (H2(q)).
|
3605 |
14707073
|
Further analyses revealed that thymic deletion required both a hybrid MHC class II molecule, Ebeta(b) Ealpha(d), and the K(d) molecule presenting the HA epitope, which together synergize to effect deletion of CD4+CD8+ thymocytes.

hIan5: the human ortholog to the rat Ian4/Iddm1/lyp is a new member of the Ian family that is overexpressed in B-cell lymphoid malignancies.
|
3607 |
14724691
|
Recently, the rat Ian4 (rIan4) was cloned and it appears to be identical to the gene Iddm1/lyp responsible for severe lymphopenia and the development of insulin-dependent diabetes in the BB-DP rat.
|
3608 |
14724691
|
Different blood fractions show high hIan5 expression in CD4- and CD8-positive T cells and monocytes, but not in B lymphocytes.
|

|
CD4, CD8 T cells and B cells were present in islet infiltrates from 9-week-old L-selectin-sufficient and -deficient littermates.

On the other hand, homing of activated, cloned insulin-specific autoaggressive CD8 T cells (TGNFC8 clone) is not affected in NOD/L-selectin-deficient recipients.

We studied the histo- and immunopathology of the endocrine and exocrine pancreas and a number of other organs in a new insulin-dependent diabetes mellitus (IDDM) rat model (LEW.1AR1/Ztm- iddm rat).
|
3612 |
14735361

The islet infiltrate was composed mainly of ED1-positive macrophages and T lymphocytes, comprising a large number of CD8(+) lymphocytes and a few CD4(+) lymphocytes.

The p38 mitogen-activated protein kinase (MAPK) pathway is important in Th1 immunity, macrophage activation, and apoptosis.
|
3614 |
14741738
|
Since they may be associated with beta-cell destruction during the development of type 1 diabetes, we investigated the role of the p38 MAPK pathway in female nonobese diabetic (NOD) mice.
|
3615 |
14741738
|
Phosphorylated p38 MAPK was observed immunohistochemically in CD4+ cells that had infiltrated into the islets and part of beta-cells, increasing in proportion to the severity of insulitis.
|
3616 |
14741738
|
Continuous oral administration of 0.08% FR167653, a specific p38 MAPK pathway inhibitor, significantly reduced the ex vivo production of interferon-gamma by splenic Th1 cells without affecting interleukin-4 production by Th2 cells.
|
3617 |
14741738
|
Treatment with FR167653 after insulitis had developed (i.e. from 10-30 weeks of age) also prevented diabetes, further suggesting that treatment with the p38 MAPK pathway inhibitor keeps insulitis benign in NOD mice, partly by inhibiting Th1 immunity.
|
3618 |
14741738
|
These findings suggest that p38 MAPK is a key mediator that switches insulitis from benign to destructive in the development of type 1 diabetes.

Autoreactive CD4(+) T helper cells and CD8(+) cytotoxic T lymphocytes (CTLs) recognize b-cell-derived peptides in the context of major histocompatibility complex class II and I molecules, respectively, in a process that terminates in b-cell death.

Here we show that a transient pulse of transforming growth factor beta (TGF-beta) in the islets during the priming phase of diabetes is sufficient to inhibit disease onset by promoting the expansion of intraislet CD4+CD25+ T cell pool.
|
3669 |
15070759

Approximately 40-50% of intraislet CD4+ T cells expressed the CD25 marker and exhibited characteristics of regulatory T cells including small size, high level of intracellular CTLA-4, expression of Foxp3, and transfer of protection against diabetes.

T-bet controls autoaggressive CD8 lymphocyte responses in type 1 diabetes.
|
3692 |
15096540
|
The T-box transcription factor T-bet is known to control lineage commitment and interferon-gamma production by T helper 1 (Th1) CD4 lymphocytes.
|
3693 |
15096540
|
We report here that T-bet is essential for development of CD8 lymphocyte-dependent autoimmune diabetes (type 1 diabetes [T1D]) in the rat insulin promoter-lymphocytic choriomeningitis virus (LCMV) transgenic model for virally induced T1D.
|
3694 |
15096540
|
In the absence of T-bet, autoaggressive (anti-LCMV) CD8 lymphocytes were reduced in number and produced less IFN-gamma, but increased IL-2 compared with controls.
|
3695 |
15096540
|
Further analysis showed that T-bet intrinsically controls the generation, but not apoptosis, maintenance, or secondary expansion of antiviral effector/memory CD8 lymphocytes.

In this study we initially evaluated 43 patients with recent-onset Type 1 diabetes (disease duration <or= 6 months, 29 ICA positive) with regard to beta-cell secretion stimulation test with glucagon and immunologic parameters, including CD4 +, CD8 +, CD4 + CD25 +, CD8 + CD25 + lymphocyte subsets.
|
3723 |
15127321
|
The percentage of CD4 + cells was 42 +/- 9,4 % (healthy controls 44 +/- 7.3 %, p nonsig.) and percentage of CD8 + was 33 +/- 8.6 % (healthy control 31 +/- 8.3 %, p nonsig.).
|
3724 |
15127321

Relative size of CD4 + CD25 + subpopulation was 7 +/- 5.4 % (healthy control 2 +/- 2 %, p < 0.001).
|
3725 |
15127321
|
The change in the excursion of C-peptide between baseline and follow-up visit (C-peptide6min (6month-baseline)) showed mild, negative correlation with relative size of the CD8 + CD25 + subpopulation (r = - 0.511, p = 0.025), which may indicate that the size of this cell subpopulation has predictive value in assessing future functional beta-cell changes.

Patients with TIDM had similar defects and, in addition, showed decreased counts of peripheral CD4(+)CD8(+) lymphocytes and increased serum levels of soluble receptors for interleukin (IL)-6 and IL-2.
|
3749 |
15147359
|
In the whole study group, we found a correlation (multiple R 0.5, P < 0.001) of CD23(+)CD25(+) cells with blood counts of monocytes, CD4(+)CD8(+) cells, CD25(+) cells, basal haemolysis and plasma levels of thiols.

|
3776 |
15184500

3777 |
15184500

Importantly, only 5,000 expanded CD25+ CD4+ BDC2.5 T cells could block autoimmunity caused by diabetogenic T cells in NOD mice, whereas 10(5) polyclonal, CD25+ CD4+ T cells from NOD mice were inactive.

Furthermore, the numbers of splenic CD4+CD62L+ regulatory T cells in GAD-IgG-treated mice during the prediabetic period and serum TGF-beta levels in 34-38-week-old GAD-IgG-protected mice were also increased, compared to control IgG-treated ones.
|
3942 |
15343360
|
Parallel with disease protection, we observed a prolonged increase of the numbers of CD4+CD25+ T cells in the periphery of GAD-IgG-treated mice, compared to those treated with a control IgG vector, both in the prediabetic period and persisting even 8 months after gene therapy.

Moreover, CD4+CD25+ T cells induced by GAD-IgG fusion construct were capable of suppressing the proliferative response of CD4+CD25- T cells in vitro; and ablation of the activity of CD4+CD25+ T cells by blocking antibody against CD25 could reverse GAD-specific T-cell hyporesponsiveness.

B7-2 deficiency caused a profound diminishment in the generation of spontaneously activated CD4 T cells and islet-specific CD4 T cell expansion.
|
3953 |
15356107
|
CD4 T cells showed some hallmarks of hyporesponsiveness because TCR/CD28-mediated stimulation led to defective activation and failure to induce disease in NODscid recipients.
|
3954 |
15356107
|
Furthermore, CD4 T cells exhibited enhanced death in the absence of B7-2.
|
3955 |
15356107
|
Interestingly, we found that B7-2 is required to achieve normal levels of CD4+CD25+CD62L+ T regulatory cells because a significant reduction of these T regulatory cells was observed in the thymus but not in the peripheral compartments of B7-2KO mice.
|
3956 |
15356107

Taken together these results clearly indicate that B7-2 plays a critical role in priming islet-reactive CD4 T cells, suggesting a simplified, two-cell model for the impact of this costimulatory molecule in autoimmunity against islets.

In NOD mice, CD28/B7 and CD40/CD40 ligand (L) interactions control the onset of diabetes from 2 to 4 weeks of age, but blocking these molecules has little effect after this time.
|
4004 |
15368274
|
We now show that OX40 is expressed on CD4 and CD8 T cells several weeks prior to islet destruction, which is initiated around weeks 12-14, and that OX40L is present on dendritic cells in both secondary lymphoid organs and the pancreas from 11 to 13 weeks of age.

While CD4(+) T cells from NOD mice secreted IFN-gamma, IL-4, IL-5 and IL-10 in response to LACK, those from LACK-expressing Tg mice secreted reduced levels of cytokines.

4006 |
15380036
|
Three forms of these regulatory T cells have been described: those that function via the production of the cytokine IL-10 (T regulatory 1 cells), transforming growth factor beta (Th3 cells), and a population of T cells that suppresses proliferation via a cell-contact-dependent mechanism (CD4+CD25+ TR cells).

Phenotypically "immature" dendritic cells (DCs), defined by low cell surface CD40, CD80, and CD86 can elicit host immune suppression in allotransplantation and autoimmunity.
|
4008 |
15383562
|
CD40, CD80, and CD86 cell surface molecules were specifically down-regulated by treating NOD DCs ex vivo with a mixture of antisense oligonucleotides targeting the CD40, CD80, and CD86 primary transcripts.
|
4009 |
15383562
|
Engineered DC promoted an increased prevalence of CD4(+)CD25(+) T cells in NOD recipients at all ages examined and diabetes-free recipients exhibited significantly greater numbers of CD4(+)CD25(+) T cells compared with untreated NOD mice.

Treatment of NOD mice with a mitogenic anti-CD3 depletes CD4(+)CD25(-)CD62L(+) but not CD4(+)CD25(+)CD62L(+) T cells, thereby resulting in an increase of the latter subset in the spleen.
|
4011 |
15383571
|
These results demonstrate that the capacity of anti-CD3 to protect NOD mice from T1D correlates with its ability to perturb T cell homeostasis by inducing CD8(+) T cell AICD and increasing the number of CD4(+)CD25(+)CD62L(+) T cells in the periphery.

Moreover, the residual proliferation of the autoreactive cells was effectively controlled by CD28-dependent CD4+CD25+ regulatory T cells (Treg's), as depletion of Treg's partially restored proliferation of autoreactive T cells and resulted in diabetes in an adoptive-transfer model.

|
4021 |
15468055
|
These CTLA-4-deficient Treg expressed increased levels of the suppressive cytokines IL-10 and TGF-beta, and in vitro suppression mediated by CTLA-4(-/-) Treg was markedly reduced by neutralizing TGF-beta, suggesting that CTLA-4-deficient Treg develop a compensatory suppressive mechanism through CTLA-4-independent production of TGF-beta.

|
4028 |
15470032
|
These mice also exhibited a defect in T lymphocyte development, leading to excessive numbers of mature T cells (CD4+ and CD8+), due to a maturation stage-specific defect in the apoptosis of thymocytes and peripheral T cells.
|
4029 |
15470032
|
Furthermore, E2f1-deficient mice showed a profound decrease of immunoregulatory CD4+CD25+ T cells, while the spleen cells of NOD mice lacking E2f1 showed a significant increase of the proinflammatory cytokine IFN-gamma following antigenic stimulation in vitro.
|
4030 |
15470032

Additional signaling pathways and molecules, such as the Janus kinase pathway and vascular endothelial growth factor have been added to those recognized as important in pharmacologic immunosuppression, and the concepts of regulation, once polarized between CD8+ and CD4+ camps, have begun to converge upon a recognition that there are many phenotypes of regulatory cells.

Loss of one copy of Aire diminished thymic expression of the endogenous insulin gene and the transgene, resulting in a 300% increase in islet-reactive CD4 T cells escaping thymic deletion in T cell receptor transgenic mice, and dramatically increased progression to diabetes.

However, CD4+CD25+ thymocytes were much less sensitive than their CD4+CD25- companions, by two to three orders of magnitude, to agonist-induced clonal deletion, such that their proportion increased, giving the false impression of induced differentiation.

|
To account for these and prior observations, one can propose that differentiation along the CD4+CD25+ pathway is induced by cues other than recognition of self-agonist cues, which are poorly read by thymocytes, whose T cell receptors are conducive to selection toward the conventional CD4+CD25- lineage.

CTLA-4, a homologue of CD28, is a negative regulator of T cell activation in the periphery and is transiently expressed on the cell surface after T cell activation.
|
4123 |
15557155
|
This investigation was initiated to determine the role of CTLA-4 in the activation of CD4(+)CD8(+) double-positive (DP) and CD4(+)CD8(-) and CD4(-)CD8(+) single-positive (SP) thymocytes using fetal thymic organ cultures (FTOC) of MHC class II-restricted, OVA(323-339)-restricted TCR transgenic mice (DO11.10).
|
4124 |

Although the Ags for G9C8 and 8.3 are known to be insulin and islet-specific glucose-6-phosphatase catalytic subunit-related protein, respectively, only mimotope peptides had previously been identified for AI4.
|
4128 |

|
4130 |
15557171

The N221(+) T cells produced IFN-gamma and IL-10, but very little IL-4, in response to p221 stimulation.
|
4131 |
15557171

This suppressive activity was cell contact-independent and was abrogated by Abs to IL-10 or IL-10R.
|
4132 |

Accumulating evidence that granulocyte colony-stimulating factor (G-CSF), the key hematopoietic growth factor of the myeloid lineage, not only represents a major component of the endogenous response to infections, but also affects adaptive immune responses, prompted us to investigate the therapeutic potential of G-CSF in autoimmune type 1 diabetes.

|
The mechanisms involved in maintenance of peripheral tolerance include a specialized subset of regulatory T-cells (Treg) within the CD4(+)CD25(+) T-cell population, but the function and phenotype of these cells in type 1 diabetes have not been investigated.
|
4150 |
15616015

We hypothesized that a deficiency in the CD4(+)CD25(+) Treg population or its function could contribute to the lack of self-tolerance evident in patients with type 1 diabetes.
|
4151 |
15616015
|
We show that although levels of CD4(+)CD25(+) T-cells are normal in patients with recent-onset adult type 1 diabetes, the ability of the Tregs in this population to suppress T-cell proliferation during in vitro cocultures is markedly reduced compared with control subjects (P = 0.007).
|
4152 |
15616015
|
Moreover, in patients with type 1 diabetes, these cocultures display a more proinflammatory phenotype, with increased secretion of interferon-gamma (P = 0.005) and decreased interleukin-10 production (P = 0.03).
|
4153 |
15616015
|
These deficiencies may reflect a disturbance in the balance of the CD4(+)CD25(+) population, because in patients with type 1 diabetes, a higher proportion of these cells coexpress the early activation marker CD69 (P = 0.007) and intracellular CTLA-4 (P = 0.01).

We show that although levels of CD4(+)CD25(+) T-cells are normal in patients with recent-onset adult type 1 diabetes, the ability of the Tregs in this population to suppress T-cell proliferation during in vitro cocultures is markedly reduced compared with control subjects (P = 0.007).

|
CD4+ CD25+ T-cells appear to play a crucial role in regulating the immune response.
|
4420 |
15855327
|
Therefore, we evaluated the peripheral blood frequency and function of CD4+ CD25+ T-cells in 70 type 1 diabetic patients and 37 healthy individuals.
|
4421 |
15855327
|
Interestingly, a positive correlation was observed between increasing age and CD4+ CD25+ T-cell frequency in both subject groups.
|
4422 |
15855327
|
In contrast to previous studies of nonobese diabetic mice and type 1 diabetic patients, similar frequencies of CD4+ CD25+ and CD4+ CD25(+Bright) T-cells were observed in healthy control subjects and type 1 diabetic patients of similar age.
|
4423 |
15855327
|
There was no difference between type 1 diabetic subjects of recent-onset versus those with established disease in terms of their CD4+ CD25+ or CD4+ CD25(+Bright) T-cell frequency.
|
4424 |
15855327
|
This type 1 diabetes-associated defect in suppression was associated with reduced production of interleukin (IL)-2, gamma-interferon, and transforming growth factor-beta, whereas other cytokines including those of adaptive and innate immunity (IL-10, IL-1beta, IL-6, IL-8, IL-12p70, and tumor necrosis factor-alpha) were similar in control subjects and type 1 diabetic patients.
|
4425 |
15855327
|
These data suggest that age strongly influences the frequency of CD4+ CD25+ T-cells and that function, rather than frequency, may represent the means by which these cells associate with type 1 diabetes in humans.

When diabetic mice are treated with the RANKL antagonist osteoprotegerin (OPG), there is a significant reversal of alveolar bone loss, as well as reduced RANKL expression in A. actinomycetemcomitans-reactive CD4+ T-cells.
|
4476 |
15855336
|
Thus, microorganism-reactive CD4+ T-cells and the RANKL-OPG axis provide the molecular basis of the advanced periodontal breakdown in diabetes and, therefore, OPG may hold therapeutic potential for treating bone loss in diabetic subjects at high risk.

The c-Jun NH(2)-terminal kinase isoform (JNK) 1 is implicated in type 2 diabetes.
|
4480 |
15867147
|
Here, we demonstrate that JNK2 may play an important role in type 1 (insulin-dependent) diabetes that is caused by autoimmune destruction of beta cells.
|
4481 |
15867147
|
CD4(+) T cells from JNK2-deficient nonobese diabetic mice produced less IFN-gamma but significantly increased amounts of IL-4 and IL-5, indicating polarization toward the Th2 phenotype.
|
4482 |
15867147
|
We conclude that JNK protein kinases may have important roles in diabetes, including functions of JNK1 in type 2 diabetes and JNK2 in type 1 diabetes.

CD8+ T cell tolerance in nonobese diabetic mice is restored by insulin-dependent diabetes resistance alleles.

16034108
|
In the current study we have used NOD-InsHA transgenic mice that express the influenza hemagglutinin (HA) as an islet Ag to compare the fate of HA-specific CD8+ T cells in diabetes susceptible NOD-InsHA mice with that observed in diabetes-resistant congenic mice having protective alleles at insulin-dependent diabetes (Idd) 3, Idd5.1, and Idd5.2 (Idd3/5 strain) or at Idd9.1, Idd9.2, and Idd9.3 (Idd9 strain).

16034108
|
However, by following the fate of naive, CFSE-labeled, islet Ag-specific CD8+ (HA-specific clone-4) or CD4+ (BDC2.5) T cells, we observed that tolerance is achieved differently in each protected strain.
|
4542 |
16034108

In Idd3/5 mice, tolerance occurs during the initial activation of islet Ag-specific CD8+ and CD4+ T cells in the pancreatic lymph nodes where CD25+ regulatory T cells (Tregs) effectively prevent their accumulation.
|
4543 |
16034108
|
In contrast, resistance alleles in Idd9 mice do not prevent the accumulation of islet Ag-specific CD8+ and CD4+ T cells in the pancreatic lymph nodes, indicating that tolerance occurs at a later checkpoint.

Our results indicate that (1) autoreactive CD4 T cells to GAD65 autoantigen are commonly present in humans expressing diabetes-susceptible HLA-DR*0401 molecules; (2) these autoreactive T cells undergo avidity maturation upon encountering the self antigen early in life; (3) the disease is associated with an imbalance between autoreactive CD4+CD25+ and CD4+CD69+ T cells specific for GAD65.

CD4(+)CD25(+) T cells represent 5-10% of CD4(+) thymocytes or peripheral T cells from prediabetic neonatal NOD mice, are anergic to TCR signals, and potently suppress activated T cells in a contact-dependent and cytokine-independent fashion in vitro.

Unlike total CD4(+) T cells, prediabetic CD25(+)-depleted CD4(+) T cells are potently diabetogenic when transferred in immunodeficient NOD mice.

16126946
|
Co-transfer of CD4(+)CD25(+) T cells from thymocytes or peripheral lymphoid tissues of neonatal NOD mice dramatically halts disease development and beta-islet cell lymphocytic infiltration, even when T1D is induced by CD4(+) T cells from BDC2.5 transgenic or diabetic NOD mice.

4632 |
16126946

Finally, we show that CD4(+)CD25(+) T(reg) preferentially accumulate in inflamed pancreatic environments, where they potently inhibit the antigen-specific expansion and cytokine effector functions of diabetogenic T cells.
|
4633 |
16126946
|
Thus, CD4(+)CD25(+) T cell-mediated regulation is operative in the prediabetic neonatal T cell repertoire and can suppress the diabetogenic process and control the onset of T1D.

Although major histocompatibility complex (MHC) class II-restricted CD4 T cells are well appreciated for their contribution to peripheral tolerance to tissue allografts, little is known regarding MHC class I-dependent reactivity in this process.
|
4651 |
16155578
|
Here we show a crucial role for host MHC class I-dependent NK cell reactivity for allograft tolerance in mice induced through either costimulation blockade using CD154-specific antibody therapy or by targeting LFA-1 (also known as CD11a).
|
4652 |

Particular interest has focused on the CVB4 non-structural protein P2C, which we previously showed to be a major target of the effector memory anti-CVB4 CD4 T-cell response, and which harbours a region of sequence similarity with the islet autoantigen, glutamic acid decarboxylase (GAD65).
|
4661 |

Moreover, neonatal treatment with TNF-alpha resulted in skewed development of a CD8alpha(+)CD11b(-)CD11c(+) DC subset such that TNF-alpha decreases the CD8alpha(+)CD11c(+) DC subset, increases the CD11c(+)CD11b(+) subset, and causes an increase in the expression of CD40 and CD54 on mature DCs capable of inducing immunity.
|
4665 |

|
4669 |
16249070
|
A slightly higher percentage of diabetic subjects had GAD65(555-567) tetramer-positive T cells upon GAD65(555-567) peptide stimulation on the total CD4+ T-cell populations compared to healthy subjects.

We investigated whether iNKT activation with alpha-GalCer was protective in collagen-induced arthritis (CIA) in DBA/1 mice, a standard model of rheumatoid arthritis.
|
4748 |
16304639
|
Here, we have shown that in vivo iNKT cell function was altered in DBA/1 mice since stimulation with alpha-GalCer led to decreased IL-4 and IFN-gamma levels in sera, as compared with C57BL/6 mice. alpha-GalCer induced a clear-cut diminution of clinical and histological arthritides.
|
4749 |
16304639
|
An anti-IL-10 receptor antibody abrogated the protective effect of alpha-GalCer, suggesting a key role for IL-10 in the protection against CIA by activated iNKT cells.
|
4750 |
16304639
|
Confirming these data, disease protection conferred by alpha-GalCer correlated with the ability of LN CD4+ cells to secrete larger amounts of IL-10.

Costimulation blockade of both inducible costimulator and CD40 ligand induces dominant tolerance to islet allografts and prevents spontaneous autoimmune diabetes in the NOD mouse.
|
4764 |
16380473
|
Using a fully allogeneic mouse model, we tested the effectiveness of the combined blockade of the CD40 ligand and the inducible costimulator (ICOS) on islet allograft survival and in the prevention of autoimmune diabetes in the NOD mouse.
|
4765 |
16380473

4766 |
16380473
|
The immunohistology of tolerant grafts demonstrated the presence of CD4(+)CD25(+) T-cells expressing Foxp3, and islet/kidney composite grafts from tolerant mice, but not from mice lacking lymphocytes, were accepted indefinitely when transplanted into naïve B6 mice, suggesting that recipient T-cells were necessary to generate dominant tolerance.
|
4767 |
16380473
|
These data demonstrate that the blockade of CD40 ligand and ICOS signaling induces islet allograft tolerance involving a dominant mechanism associated with intragraft regulatory cells and prevents autoimmune diabetes in NOD mice.

16476010
|
Compared with the control mice, newborn mice treated with monoclonal antibody (MoAb) against mouse CD25(+) CD4(+) T cells together with Reo-2 and CpG ODN greatly reduced the absolute number of splenic CD25(+) T cells and resulted in the development of severe insulitis, leading to an overt early diabetes.

Compared with the control mice, newborn mice treated with monoclonal antibody (MoAb) against mouse CD25(+) CD4(+) T cells together with Reo-2 and CpG ODN greatly reduced the absolute number of splenic CD25(+) T cells and resulted in the development of severe insulitis, leading to an overt early diabetes.

|
Moreover, the treatment of the MoAb increased production of interferon-gamma (IFN-gamma) and decreased that of interleukin-4 (IL-4) and transforming growth factor-beta1 (TGF-beta1) and developed high titre of autoantibodies against pancreatic islet cells.

16478885

CD4(+)CD25(+) T cells have been implicated in HCV persistence because their frequency is increased in the blood of HCV-infected patients and their in vitro depletion results in increased IFN-gamma production by HCV-specific T cells.
|
4861 |
16478885
|
Studying a well-characterized cohort of 16 chimpanzees, the sole animal model for HCV infection, we here demonstrate that the frequency of Foxp3(+)CD4(+)CD25(+) regulatory T cells (T(Regs)) and the extent of suppression was as high in spontaneously HCV-recovered chimpanzees as in persistently HCV-infected chimpanzees.

Targeted disruption of CD38 accelerates autoimmune diabetes in NOD/Lt mice by enhancing autoimmunity in an ADP-ribosyltransferase 2-dependent fashion.
|
4956 |
16585549
|
Ubiquitously expressed CD38 and T cell-expressed ADP-ribosyltransferase 2 (ART2) are ectoenzymes competing for NAD substrate.
|
4957 |
16585549
|
ART2 is an ADP-ribosyltransferase on naive CD4+ and CD8+ T cells.
|
4958 |
16585549
|
Transfer of a genetically disrupted CD38 allele into the autoimmune diabetes-prone NOD/Lt background accelerated diabetes onset in both sexes, whereas transfer of a disrupted ART2 complex had no effect.
|
4959 |
16585549
|
However, the fact that the accelerated pathogenesis mediated by CD38 deficiency required ART2 activity was demonstrated by combining both ART2 and CD38 deficiencies.
|
4960 |
16585549
|
Rather, the balance between T-effectors and T-regulatory cells was disturbed in CD38-deficient but ART2-intact NOD mice.
|
4961 |
16585549
|
These changes were corrected when CD38 deficiency was combined with ART2 deficiency.
|
4962 |
16585549
|
Both ART2-deficient and CD38/ART2 combined deficient T cells were resistant to NAD-induced killing in vitro, whereas CD38-deficient but ART2-intact T cells showed increased sensitivity, particularly the CD4+ CD25+ subset.
|
4963 |
16585549
|
Unexpectedly, diabetes development in the combined CD38/ART2 stock was strongly suppressed, possibly through epistatic interactions between genes linked to the targeted CD38 on Chromosome 5 and the ART2 complex on Chromosome 7.

However, the fact that the accelerated pathogenesis mediated by CD38 deficiency required ART2 activity was demonstrated by combining both ART2 and CD38 deficiencies.
|
4969 |
16585549
|
Rather, the balance between T-effectors and T-regulatory cells was disturbed in CD38-deficient but ART2-intact NOD mice.
|
4970 |
16585549
|
These changes were corrected when CD38 deficiency was combined with ART2 deficiency.
|
4971 |
16585549
|
Both ART2-deficient and CD38/ART2 combined deficient T cells were resistant to NAD-induced killing in vitro, whereas CD38-deficient but ART2-intact T cells showed increased sensitivity, particularly the CD4+ CD25+ subset.
|
4972 |
16585549
|
Unexpectedly, diabetes development in the combined CD38/ART2 stock was strongly suppressed, possibly through epistatic interactions between genes linked to the targeted CD38 on Chromosome 5 and the ART2 complex on Chromosome 7.

PD-1 has two ligands: PD-1 ligand 1 (PD-L1), which is expressed broadly on hematopoietic and parenchymal cells, including pancreatic islet cells; and PD-L2, which is restricted to macrophages and dendritic cells.
|
4986 |
16606670
|
To investigate whether PD-L1 and PD-L2 have synergistic or unique roles in regulating T cell activation and tolerance, we generated mice lacking PD-L1 and PD-L2 (PD-L1/PD-L2(-/-) mice) and compared them to mice lacking either PD-L.
|

MG administration effectively regulated the immune imbalance in diabetic mice, principally by upregulating the CD4(+) T lymphocyte subsets, and remodeling the intracellular cytokine profiles (reducing the expression of pro-inflammatory Th1 cytokines towards a beneficial Th2 pattern), ascribed to its induction and upregulation of HO-1.

We have shown previously that incorporation of a cDNA coding for the pro-apoptotic protein BAX into plasmid DNA coding for a secreted form of the pancreatic beta-cell antigen glutamic acid decarboxylase (GAD) promotes prevention of type 1 diabetes in non-obese diabetic (NOD) mice.

|
Data also revealed that CD4(+)CD25(-) T cells from mice immunized with the DNA vaccine yielded a cell population that was foxp3(+), showed increased expression of CD25 compared to control, and had immunosuppressive function in vitro, indicating that Tregs could have developed from antigen-induced, peripheral T lymphocytes.

NTX had only a minor effect in NOD mice protected from diabetes by transgenic expression of the beta cell autoantigen proinsulin in APCs, inferring that accelerated diabetes after NTX is largely due to failure to regulate proinsulin-specific T cells.

5012 |
16709812

IL-1 is a key proinflammatory driver of several autoimmune diseases including juvenile inflammatory arthritis, diseases with mutations in the NALP/cryopyrin complex and Crohn's disease, and is genetically or clinically associated with many others.
|
5022 |
16751371
|
Here we show that autoimmune-prone NOD and IL-1 receptor antagonist-deficient C57BL/6 mice both produce high levels of IL-1, which drives autoreactive effector cell expansion.
|
5023 |
16751371
|
IL-1beta drives proliferation and cytokine production by CD4(+)CD25(+)FoxP3(-) effector/memory T cells, attenuates CD4(+)CD25(+)FoxP3(+) regulatory T cell function, and allows escape of CD4(+)CD25(-) autoreactive effectors from suppression.

We report in this study that leptin receptor (ObR) is expressed on resting normal mouse CD4(+), CD8(+), B cells, and monocyte/macrophages.
|
5025 |
16751422
|
Leptin binding to ObR results in increased STAT-3 activation in T cells, with a different activation pattern in resting vs anti-CD3 Ab stimulated T cells.
|
5026 |
16751422
|
B lymphocytes appear to be more susceptible to the antiapoptotic effects of leptin, and they show higher surface expression of ObR, compared with T cells.
|
5027 |
16751422
|
Moreover, CD4(+) T cells isolated from ObR-deficient mice displayed a reduced proliferative response, compared with normal controls.
|
5028 |
16751422
|
Furthermore, ObR/STAT-3-mediated signaling in T lymphocytes is decreased in the diet-induced obese mouse model of obesity and leptin resistance.
|
5029 |
16751422
|
In summary, our findings show that the ObR is expressed on normal mouse lymphocyte subsets, that leptin plays a role in lymphocyte survival, and that leptin alters the ObR/STAT-3-mediated signaling in T cells.

Genetic studies demonstrated a 34.4 kb deletion at Xq28 which included AVPR2, the gene responsible for NDI; ARHGAP4, a hematopoietic specific gene encoding a GTPase-activating protein; and a highly conserved segment of DNA between ARHGAP4 and ARD1A, a gene involved in the response to hypoxia.
|
5037 |
16781893
|
Other patients with NDI, but without immunodeficiency, have had deletions that remove all ARHGAP4 except exon 1; however, no other patients have had deletions of the highly conserved intragenic region between ARHGAP4 and ARD1A.
|
5038 |
16781893
|
X chromosome inactivation studies, done on sorted cells from the mother and grandmother of the patient, carriers of the deletion, demonstrated exclusive use of the non-mutant X chromosome as the active X in CD4 and CD8 T cells.

Furthermore, we could not identify a role for putative specific T cells regulating proinsulin-2-reactive CD4+ T in transfer experiments.

Lower percentages of CD4+ T cells (P = 0.03) and CD4+ CD25high cells (P = 0.06) expressing intracellular CTLA-4 were detected in samples from children with CTLA-4 +49GG compared to children with the +49AA genotype.

Similarly, lower percentages of CD4+ (P = 0.002) and CD4+ CD25high (P = 0.002) cells expressing CTLA-4 were observed in children positive for HLA DQA1*0501-DQB1*0201 and DQA1*0301-DQB1*0302 (P = 0.04 for CD4+ and P = 0.02 for CD4+ CD25high) risk haplotypes when compared to children without these alleles.

|
5111 |
16804081

5112 |
16804081

Interestingly, APCs from disease-free (>30 weeks of age), but not diabetic, NOD mice were able to activate CD4(+)CD25(+) regulatory function in vitro and apparently in vivo because only spleens of disease-free NOD mice contained potent CD4(+)CD25(+) regulatory cells that prevented disease development when transferred into young NOD recipients.

Interaction of antigen-presenting cell CD1d with distinct natural killer T-cell ("NKT") populations can induce rapid gamma interferon (IFN-gamma) production and NK-cell activation.
|
5157 |

The purpose of this study was to observe the islet changes of pancreas in insulin-dependent diabetes mellitus (IDDM) mice in comparison to normal mice after application of an extract from Siraitia grosvenori fruits containing mogrosides, in particular, mogroside V.

In addition, alloxan induced a notable increase in the expression of CD8+ lymphocytes to form a dramatic decrease in CD4+/CD8+ ratio (while CD4+ was unchanged).

During the past 10 years, CD4(+)CD25(+)Foxp3(+) regulatory T cells (Treg) have been extensively studied for their function in autoimmune disease.
|
5184 |
16838180

However, downmodulation of dendritic cell function and secretion of inhibitory cytokines such as IL-10 and TGF-beta might underlie Treg function in vivo.

Therefore, we conclude that CD4+, CD25+ regulatory T cells are required for the induction as well as maintenance of tolerance in this gene therapy model.

Recently, we have identified proinsulin (P-Ins)(73-90) as an immunodominant T cell epitope of HLA-DRB1*0401 (DR4) subjects with beta-islet cell autoimmunity and of HLA-DR4/CD4 double-transgenic mice immunized with human P-Ins.
|
5187 |
16868084
|
The human T cell clone was forkhead transcription factor 3 (Foxp3)-positive, a marker for regulatory T cell lineages, and secreted predominantly IL-5, IL-10, and low levels of IFNgamma in response to P-Ins(73-90).

Neither the introduction of activated, self-antigen-specific CD4(+) helper T cells nor a global inflammatory stimulus were sufficient to activate the low-avidity CD8(+) T cells and did not break tolerance.

We found that in the absence of CD38, ADP-ribosyltransferase 2 preferentially activates apoptotic deletion of peripheral iNKT cells, especially the CD4+ subset.

We found that CD4+ CD25+ T cells from NOD.CD1d(-/-) mice deficient in iNKT cell function similarly in vitro to CD4+ CD25+ T cells from wild-type NOD mice and suppress the proliferation of NOD T responder cells upon alpha-GalCer stimulation.

Cotransfer of NOD diabetogenic T cells with CD4+ CD25+ Tregs from NOD mice pretreated with alpha-GalCer demonstrated that activated iNKT cells do not influence the ability of T(regs) to inhibit the transfer of T1D.

In contrast, protection from T1D mediated by transfer of activated iNKT cells requires the activity of CD4+ CD25+ T cells, because splenocytes pretreated with alpha-GalCer and then inactivated by anti-CD25 of CD25+ cells did not protect from T1D.

In addition, the vitamin D(3) analog did not stimulate an enhancement in the expression of CD4 and CD25 in BB rats as it does in NOD mice, which may explain the failure of this as well as other antidiabetic treatments in the BB animal model of type 1 diabetes.

B7-H4.Ig protein was purified from the culture supernatant of 293T cells transfected by a B7-H4.Ig plasmid (pMIgV, containing a human B7-H4 cDNA and a mouse IgG2a Fc cDNA).

BB rats were therefore checked at day 21 up to day 90 of life for blood glucose, insulin levels, degree of islet infiltration, expression of proinflammatory and protective cytokines and antibodies including CD4, CD8, CD25, LFA-1, and ICAM-1.
|
5250 |
16972262

We found that islets of non-diabetic BB rats became positive to both IL-1beta and IL-4 very early on, confirming a local but intense production of both cytokines within the islets during the initial non-diabetic period.
|
5251 |
16972262
|
In addition, we observed that the production of these interleukins together with the expression levels of CD4 and CD25 are events predictive for type 1 diabetes onset in non-diabetic BB rats, as for non-obese diabetic (NOD) mice.
|
5252 |
16972262

In particular, the production of IL-1beta and IL-4 during the non-diabetic period together with the lack of enhancement of CD4 and CD25, indicating selective recruitment of activated T cells, may explain the failure of anti-diabetic treatments in this animal model of type 1 diabetes.

We have identified for the first time an age-dependent spontaneous loss of tolerance to two self-antigenic epitopes derived from putative diabetes-associated antigens glutamic acid decarboxylase (GAD65) and glial fibrillary acidic protein (GFAP) in RIP-B7/DRB1*0404 HLA transgenic mice.
|
5262 |
16979383
|
Diabetic and older non-diabetic mice exhibited a proliferative response to an immunodominant epitope from GAD65 (555-567) and also from GFAP (240-252) but not from an immunogenic epitope from diabetes-associated islet-specific glucose-6-phosphatase catalytic subunit-related protein.

Islet infiltrates in older non-diabetic mice and diabetic mice contain CD4(+)/FoxP3(+) cells and suggest the presence of a regulatory mechanism prior and during diabetic disease.

Furthermore, it is our contention, that in response to beta cell apoptosis during normal remodeling of the pancreas and CCL19/CCL21 expression within the pancreatic lymph nodes (PLNs), gluten-loaded dendritic cells migrate from the small intestine to the PLNs.
|
5321 |
17045415
|
These dendritic cells present gluten-derived antigens on the surface of the PLNs, which leads to migration of CD4(-)CD8(-) gammadelta and CD4(-)CD8(+) alphabeta T cells to the pancreas where they mediate Fas and perforin dependent cytotoxicity.

|
SOCS-1 protects from virally-induced CD8 T cell mediated type 1 diabetes.
|
5323 |
17045460
|
CTL-mediated beta-cell killing can occur via perforin-mediated lysis, Fas-Fas-L interaction, and the secretion of TNF-alpha or IFN-gamma.
|
5324 |
17045460
|
Suppressor of cytokine signaling-1 (SOCS-1) represses several crucial cytokine signaling pathways simultaneously, among them IFN-gamma and IL-1-beta.
|
5325 |
17045460
|
We therefore evaluated the protective capacity of islet cell SOCS-1 expression in the CD8(+) mediated RIP-LCMV diabetes model.
|
5326 |
17045460
|
Not only absence of MHC-I and Fas upregulation, but also resistance to cytokine-induced killing of beta-cells and a complete lack of CXCL-10 (IP10) production in islets led to a lack of islet infiltration and impaired activation of autoaggressive CD4(+) and CD8(+) T-cells in these mice.
|
5327 |

|
Two recent studies have demonstrated that downregulation of the interleukin-7 receptor (CD127) distinguishes Treg cells from activated T cells, facilitating both Treg-cell purification and their functional characterization in human diseases.
|
5328 |
17045841
|
CD127 uniquely enables the purification of FOXP3+ Treg cells and, potentially, also "adaptive" regulatory T-cell subsets from the CD4+CD25- T-cell population.
|

|
Cellular interactions promoting the in vivo expansion of CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells for maintenance of immune tolerance remain poorly defined.
|
5330 |
17081781
|
Here we report that mobilized Lin(-)Sca-1(+)c-kit(+) (LSK) hematopoietic progenitor cells (HPCs), unlike medullary hematopoietic stem cells (HSCs), selectively drove the direct, immediate expansion of functional host-derived Treg cells, thereby preventing the progression to overt spontaneous autoimmune diabetes in nonobese diabetic mice.
|
5331 |
17081781
|
Treg cell expansion required cell-to-cell contact and Notch3 signaling, which was mediated selectively through the Notch ligand Jagged2 expressed by the multipotent HPC subset, as assessed by small interfering RNA (siRNA) silencing.

Here we demonstrate that disease-associated autoreactive T cells from patients with type-1 diabetes mellitus or rheumatoid arthritis (RA) are mainly CD4+ CCR7- CD45RA- effector memory T cells (T(EM) cells) with elevated Kv1.3 potassium channel expression.
|
5359 |
17088564
|
In T(EM) cells, Kv1.3 traffics to the immunological synapse during antigen presentation where it colocalizes with Kvbeta2, SAP97, ZIP, p56(lck), and CD4.
|
5360 |
17088564
|
Although Kv1.3 inhibitors [ShK(L5)-amide (SL5) and PAP1] do not prevent immunological synapse formation, they suppress Ca2+-signaling, cytokine production, and proliferation of autoantigen-specific T(EM) cells at pharmacologically relevant concentrations while sparing other classes of T cells.

Upregulation of Foxp3 expression in mouse and human Treg is IL-2/STAT5 dependent: implications for the NOD STAT5B mutation in diabetes pathogenesis.
|
5446 |
17130555
|
Regulatory T cells (Treg), characterized as CD4(+)/CD25(+hi) T cells, are critical for sustaining and promoting immune tolerance.
|
5447 |
17130555
|
Based on the presence of five STAT5B consensus sequences in the Foxp3 promotor, we hypothesized a critical linkage between IL-2 signaling/STAT5B and Foxp3 expression in Treg.
|
5448 |
17130555
|
Our data show IL-2 activates long-form (LF) STAT5 and sustains Foxp3 expression in Treg.
|
5449 |
17130555
|
In contrast, CD4(+)/CD25(-) T cells do not active LF STAT5 and do not express Foxp3 under the same conditions.
|
5450 |
17130555
|
Examination of human Treg using flow cytometry and intracellular staining for Foxp3 expression likewise demonstrates that IL-2 maintains Foxp3 expression through LF STAT5 signaling.

This article describes the regulation of human CD4+ T cell responses to glutamic acid decarboxylase 65 (GAD65), an autoantigen implicated in type-1 diabetes, by autologous CD8+ suppressor T cells.
|
5534 |
17163450
|
In cells cultured from healthy individuals, the inclusion of autologous CD8+ T cells at physiological levels resulted in a dramatic decrease in the magnitude of in vitro CD4+ T cell responses to GAD65 peptide.
|
5535 |
17163450
|
Cell fractionation studies suggested that CD8+ suppressor T cells originate from the CD45RA+ CD27- population.
|
5536 |
17163450
|
The suppression of CD4+ T cell responses to GAD65 in healthy individuals raises the possibility that CD8+ suppressor T cells play an important role in controlling potentially autoreactive T cells in the general population.

Distinct regulation of autoreactive CD4 T cell expansion by interleukin-4 under conditions of lymphopenia.
|
5573 |
17164429
|
Here, we show that IL-4 only enhances the expansion of autoreactive CD4 T cells during lymphopenia and that neither the presence of islet IL-4 nor IL-4 deficiency affects T cell expansion significantly under conditions of immunosufficiency.
|
5574 |
17164429

The ability of IL-4 to promote autoreactive CD4 T cell expansion is therefore sensitive to the degree of host immunodeficiency.

Modulating redox balance led to decreased Ag-specific T cell proliferation and IFN-gamma synthesis by diminishing ROS production in the APC, which affected TNF-alpha levels produced by CD4(+) T cells and impairing effector function.

In this study, we report the production and characterization of a NOD.Nkrp1(b).Nkt1(b) congenic mouse strain, apply microarray expression analyses to limit candidate genes within the 95% confidence region, identify Slamf1 (encoding signaling lymphocyte activation molecule) and Slamf6 (encoding Ly108) as potential candidates, and demonstrate retarded signaling lymphocyte activation molecule expression during T cell development of NOD mice, resulting in reduced expression at the CD4(+)CD8(+) stage, which is consistent with decreased NKT cell production and deranged tolerance induction in NOD mice.

We therefore examined the recently activated circulating T cell population [CD3+, human leucocyte antigen D-related (HLA-DR+)] using cytokine production and 10 additional subset markers [CD69, CD25, CD122, CD30, CD44v6, CD57, CD71, CCR3 (CD193), CCR5 (CD195) or CXCR3 (CD183)], comparing newly diagnosed adult (ND) (age 18-40 years) patients (n=19) to patients with diabetes for >10 years [long-standing (LS), n=19] and HLA-matched controls (C, n=16).
|

17302896
|
No differences in basal or stimulated production of interleukin (IL)-4, IL-10, IL-13 or interferon (IFN)-gamma by CD3+ DR+ enriched cells were observed between the different groups of subjects.
|
5671 |
17302896
|
However, among the CD3+ DR+ population, significant expansions appeared to be present in the very small CD30+, CD69+ and CD122+ subpopulations.
|
5672 |
17302896
|
A confirmatory study was then performed using new subjects (ND=26, LS=15), three-colour flow cytometry, unseparated cells and three additional subset markers (CD38, CD134, CD4/CD25).
|

CD4(+)CD25(+)Foxp3(+) regulatory T cells (T regs) are important for preventing autoimmune diabetes and are either thymic-derived (natural) or differentiated in the periphery outside the thymus (induced).
|
5675 |
17307871
|
Here we show that beta-cell peptide-pulsed dendritic cells (DCs) from nonobese diabetic (NOD) mice can effectively induce CD4(+)CD25(+)Foxp3(+) T cells from naïve islet-specific CD4(+)CD25(-) T cells in the presence of TGF-beta1.
|
5676 |
17307871
|
These results indicate a role for DCs in the induction of antigen-specific CD4(+)CD25(+)Foxp3(+) T cells that can inhibit fully developed autoimmunity in a nonlymphopoenic host, providing an important potential strategy for immunotherapy in patients with autoimmune diabetes.

To define the parameters influencing the efficacy of antigen-specific immunotherapy once diabetes is established, plasmid DNA (pDNA) vaccination was used to suppress autoimmune-mediated destruction of syngeneic islet grafts in diabetic NOD recipients. pDNAs encoding a glutamic acid decarboxylase 65 (GAD65)-Ig molecule (pGAD65), interleukin (IL)-4 (pIL4), and IL-10 (pIL10) significantly delayed the onset of recurrent diabetes compared with pGAD65+pIL10-vaccinated recipients.
|
5684 |
17317763

Despite differences in efficacy, a similar frequency of GAD65-specific CD4(+) T-cells secreting IL-4, IL-10, or interferon-gamma were detected in mice treated with pGAD65+pIL4+pIL10 and pGAD65+pIL10.
|
5685 |

However, the frequency of FoxP3-expressing CD4(+)CD25(+)CD62L(hi) T-cells was increased in the renal and pancreatic lymph nodes of diabetic recipients vaccinated with pGAD65+pIL4+pIL10.

We herein investigated the ability of a novel multimeric form of FasL chimeric with streptavidin (SA-FasL) having potent apoptotic activity to induce apoptosis in diabetogenic T cells and modulate insulin-dependent type 1 diabetes (IDDM) in an adoptive transfer model.

17327427
|
With inclusion of this marker, two predominant populations of CD4(+)CD25(+) T-cells were identified: CD4(+)CD25(+)FOXP3(+) as well as CD4(+)FOXP3(-) T-cells expressing low levels of CD25 (CD4(+)CD25(LOW)FOXP3(-)).
|
5718 |
17327427

In all study groups, the frequency of CD4(+)CD25(+)FOXP3(+) cells was age independent, whereas CD4(+)CD25(LOW)FOXP3(-) cell frequencies strongly associated with age.
|
5719 |
17327427
|
In terms of additional markers for delineating cells of Treg lineage, FOXP3(+) cells were CD127(-) to CD127(LOW) whereas CD25(+) cells were less restricted in their expression of this marker, with CD127 expressed across a continuum of levels.
|
5720 |

Although CD4+ T-cell assays have met with limited success, CD8+ T-cells are increasingly recognized as key actors in the diabetes of the NOD mouse.
|
5737 |
17327428
|
Taking advantage of a panel of HLA-A2-restricted beta-cell epitopes derived from preproinsulin, GAD, and islet glucose-6-phosphatase catalytic subunit-related protein (IGRP), we have implemented an islet-specific CD8+ T-cell interferon-gamma enzyme-linked immunospot (ISL8Spot) assay.
|
5738 |
17336387
|
In the NOD mouse, some previous studies argued in favor of a regulatory role for GAD-specific CD4+ T cells, and no diabetogenic CD8+ T cells specific for GAD have been identified so far, discrediting the importance of GAD in beta-cell injury.
|
5739 |
17336387
|
Here, we identified, in the NOD model, a relevant GAD CD8+ T cell epitope (GAD(90-98)) using immunization with a plasmid encoding GAD, a protocol relying on in vivo processing of peptides from the autoantigenic protein.
|
5740 |
17336387
|
In pancreatic lymph nodes of naïve female NOD mice, CD8+ T lymphocytes recognizing GAD(90-98) peptide were detected during the initial phase of invasive insulitis (between 4 and 8 weeks of age), suggesting an important role for these cells in the first stage of the disease.
|
5741 |
17336387

GAD(90-98) specific CD8+ lymphocytes lysed efficiently islet cells in vitro and transferred diabetes into NOD(SCID) mice (100%).

Multiple apoptotic pathways play a role in destructive insulitis, including perforin/granzyme, Fas/Fas-ligand (FasL), and other members of the necrosis factor superfamily.
|
5744 |
17346189
|
There may be a preferential use of perforin/granzyme in CD8(+) T cell-mediated lysis, which participates in onset of autoimmunity, and a predominance of FasL in CD4(+) T cell-mediated insulitis.
|
5745 |
17346189
|
Several cytokines released in the inflammatory infiltrate induce Fas expression in beta cells, priming them to FasL-mediated apoptosis.

Targets of both CD4 and CD8 T cells are listed for human type 1 diabetes, for humanized [human leucocyte antigen (HLA)-transgenic] mouse models, and for the major spontaneous disease model, the non-obese diabetic (NOD) mouse.

Here, we develop a model where IL-2 deficiency precipitates a breakdown of self-tolerance and progression to diabetes, and its action upon diabetogenic islet-specific CD4 T cells can be tracked.
|
5753 |
17372610
|
We find that IL-2 is not required for Aire-dependent thymic clonal deletion of high-avidity diabetogenic clones, but is essential for thymic formation of islet-specific Foxp3-expressing CD4 T cells.
|
5754 |

The CXCR4/CXCL12 (SDF-1) signalling pathway protects non-obese diabetic mouse from autoimmune diabetes.
|
5762 |
17374136
|
The chemokine stromal cell-derived factor-1 CXCL-12 (SDF-1) and its ligand the CXCR4 chemokine receptor are important regulatory elements.
|
5763 |
17374136
|
CXCR4 is expressed on the surface of CD4(+) T cells, dendritic cells and B lymphocytes.
|
5764 |
17374136
|
This effect was associated with an increase of interferon (IFN)-gamma mRNA and a reduction of interleukin (IL)-4 mRNA levels both in PLNs and isolated islets.
|
5765 |
17374136
|
AMD3100 also reduced IL-4 and IL-10 production of plate-bound anti-CD3 and anti-CD28-stimulated splenocytes.
|
5766 |
17374136
|
Immunofluorescence studies indicated that AMD3100 reduced the number of CXCR4(+) and SDF-1 positive cells in the inflamed islets.
|
5767 |
17374136
|
We can conclude that the CXCL-12/CXCR4 pathway has protective effects against autoimmune diabetes.

Previous results have shown that CD4(+)CD25(+) regulatory T cells (Tregs) control autoimmunity in a spontaneous model of type 1 diabetes, the nonobese diabetic (NOD) mouse.
|
5769 |
17389382
|
This finding contrasts with a large body of work suggesting that CD4(+)CD25(high) Tregs act in a cytokine-independent manner, thus suggesting that another type of Treg is operational in this setting.

Our present results show that a subset of foxP3(+) cells present within a CD4(+)CD25(low) lymphocyte subset suppresses T cell immunity in spontaneously diabetic NOD mice in a TGF-beta-dependent manner, a functional property typical of "adaptive" regulatory T cells.
|
5771 |
17389382
|
Importantly, in two distinct in vivo models, these TGF-beta-dependent adaptive CD4(+)CD25(low) T cells can be induced from peripheral CD4(+)CD25(-) T lymphocytes by anti-CD3 immunotherapy which correlates with the restoration of self-tolerance.

Granulocyte-macrophage colony-stimulating factor prevents diabetes development in NOD mice by inducing tolerogenic dendritic cells that sustain the suppressive function of CD4+CD25+ regulatory T cells.
|
5903 |
17785799
|
The protection was associated with a marked increase in the number of tolerogenic immature splenic DCs and in the number of Foxp3+CD4+CD25+ regulatory T cells (Tregs).
|
5904 |
17785799
|
Activated DCs from GM-CSF-protected mice expressed lower levels of MHC class II and CD80/CD86 molecules, produced more IL-10 and were less effective in stimulating diabetogenic CD8+ T cells than DCs of PBS-treated NOD mice.
|
5905 |
17785799
|
Depletion of CD11c+ DCs before transfer released diabetogenic T cells from the suppressive effect of CD4+CD25+ Tregs, thereby promoting the development of diabetes.
|
5906 |
17785799
|
These results indicated that semimature DCs were required for the sustained suppressive function of CD4+CD25+ Tregs that were responsible for maintaining tolerance of diabetogenic T cells in NOD mice.

The Idd6 locus on mouse chromosome 6, which controls the development of type 1 diabetes in the NOD mouse, affects proliferation rates of T cells and the activity of regulatory CD4+CD25+ T cells.
|
5923 |
17785827
|
This phenotype correlates with a diminished proliferation capacity of both CD4+CD25- effector and CD4+CD25+ regulatory T cells upon in vitro stimulation of the TLR1/TLR2 pathway by the ligand palmitoyl-3-cysteine-serine-lysine 4, and with the constitutive down-regulation of Tnf-alpha and IL-6 in macrophages of Idd6- congenic mice.

Pancreata from female NOD mice at diagnosis and at 1, 2, 3 and 4 weeks thereafter were analysed immunohistochemically for insulin, glucagon and somatostatin cells and glucose transporter-2 (glut2) and correlated with the degree of insulitis and islet immune cell phenotypes.
|
5955 |

5960 |
17947648
|
Analysis of infiltrating cells after adoptive transfer by the diabetogenic T cell clone BDC-2.5 indicates that large numbers of cells staining for both F4/80 and CD11b are recruited into the pancreas where they are activated to make IL-1beta, TNF-alpha, and NO, and express the chemokine receptors CCR5, CXCR3, and CCR8.
|
5961 |
17947648

CD86 has sustained costimulatory effects on CD8 T cells.
|
5986 |
17947667
|
CD80 and CD86 both costimulate T cell activation.
|
5987 |
17947667
|
We have studied mice expressing rat insulin promoter (RIP)-CD80 and RIP-CD86 on the NOD and NOD.scid genetic background to generate in vivo models, using diabetes as a readout for cytotoxic T cell activation.
|
5988 |
17947667
|
However, the secondary in vivo response was maintained if T cells were activated through CD86 costimulation compared with CD80.
|
5989 |
17947667
|
In vitro, CD80 costimulation enhanced cytotoxicity, proliferation, and cytokine secretion in activated CD8 T cells compared with CD86 costimulation.
|
5990 |
17947667
|
We demonstrated increased CTLA-4 and programmed death-1 inhibitory molecule expression following costimulation by both CD80 and CD86 (CD80 > CD86).
|
5991 |
17947667
|
Furthermore, T cells stimulated by CD80 were more susceptible to inhibition by CD4(+)CD25(+) T cells.
|
5992 |
17947667
|
Overall, while CD86 does not stimulate an initial response as strongly as CD80, there is greater sustained activity that is seen even in the absence of continued costimulation.

The source of TcR was a CD4(+) T(H)1(+) T-cell clone which responded to an immunodominant epitope of the human islet protein GAD65, an epitope shared with both GAD65 and GAD67 in the mouse.
|
5994 |
17949947
|
The resulting HLA-DR4/GAD-TcR transgenic mice on a Rag2(o/o)/I-Ab(o/o)/B6 background exhibited a CD4(+) infiltrate into pancreatic islets that correlated with a loss of insulin in infiltrated islets.

5995 |
17949947
|
T cells containing the GAD65/67 (555-567) responsive TcR undergo strong negative selection as evidenced by a 10-fold lower thymocyte cellularity compared to non-TcR transgenic mice, and clonotype peripheral T cells represented approximately 1% of CD4(+) T cells in Rag2 sufficient mice.
|
5996 |
17949947
|
Upon in vitro stimulation, GAD65/67 555-567 responsive T cells secrete interferon-gamma, minimal interleukin (IL)-2 and tumor necrosis factor-alpha, and no IL-4, IL-5, IL-10, or IL-17, consistent with a T(H)1 profile.
|
5997 |

6175 |

We previously showed that immune responses against proinsulin are necessary for IGRP(206-214)-specific CD8(+) T cells to expand.
|
6176 |
18354167
|
This indicates that immunity to proinsulin is even required in the great majority of NOD8.3 mice that have a pre-existing repertoire of IGRP(206-214)-specific cells.

Preferential costimulation by CD80 results in IL-10-dependent TGF-beta1(+) -adaptive regulatory T cell generation.
|
6196 |
18453575
|
Costimulatory ligands CD80 and CD86 have different binding preferences and affinities to their receptors, CD28 and CTLA-4.
|
6197 |
18453575
|
Earlier, we demonstrated that CD80 binds to CTLA-4 with higher affinity and has a role in suppressing T cell response.
|
6198 |
18453575
|
These T cells showed TGF-beta1 on their surface and secreted TGF-beta1 and IL-10 upon restimulation.
|
6199 |
18453575
|
Although blockade of CTLA-4 and neutralization of IL-10 profoundly inhibited the induction of these TGF-beta1(+) T cells, their ability to suppress the effector T cell proliferation was abrogated by neutralization of TGF-beta1 alone.
|
6200 |
18453575
|
Induction of TGF-beta1(+) and IL-10(+) T cells was found to be independent of natural CD4(+)CD25(+) regulatory T cells, demonstrating that preferential ligation of CTLA-4 by CD80 induced IL-10 production by effector T cells, which in turn promoted the secretion of TGF-beta1.
|
6201 |
18453575
|
Treatment of prediabetic NOD mice with islet beta cell Ag-pulsed CD86(-/-) DCs, but not CD80(-/-) DCs, resulted in the induction of TGF-beta1- and IL-10-producing cells, significant suppression of insulitis, and delay of the onset of hyperglycemia.
|
6202 |
18453575
|
These observations demonstrate not only that CD80 preferentially binds to CTLA-4 but also that interaction during Ag presentation can result in IL-10-dependent TGF-beta1(+) regulatory T cell induction, reinstating the potential of approaches to preferentially engage CTLA-4 through CD80 during self-Ag presentation in suppressing autoimmunity.

We show that treatment with alpha-galactosylceramide increases the size of the CD4+CD25+ Treg cell compartment in NOD mice, and augments the expression of forkhead/winged helix transcription factor and the potency of CD4+CD25+ Treg cells to inhibit proliferation of CD4+CD25- T cells.

Moreover, blockade of IFN-alpha receptor 1 in NOD mice by a neutralizing antibody at 2-3 weeks of age significantly delayed the onset and decreased the incidence of type 1 diabetes, increased the relative number of immature dendritic cells in the PLNs, and enhanced the ability of spleen CD4(+) T cells to produce IL-4 and IL-10.

Disease progression in experimental autoimmune encephalomyelitis (EAE) is regulated by programmed death receptor 1 (PD-1) and its ligands, B7-H1 (programmed death ligand 1 (PD-L1)) and B7-DC (PD-L2).
|
6357 |
18825752
|
B7-H1 and B7-DC have negative regulatory effects upon binding PD-1 on activated T cells and B7-H1 deficiency increases severity of both diabetes and EAE.
|
6358 |
18825752
|
Our data show that the majority of CNS CD4+ T cells isolated during acute EAE are PD-1+, and T cells specific for relapse-associated epitopes express PD-1 upon antigen stimulation in the CNS.
|
6359 |

|
B7-H1 and B7-DC are differentially expressed on discrete APC populations in the inflamed CNS.
|
6360 |
18825752
|
B7-H1 and PD-1 have mainly inhibitory functions on CNS T cells.
|
6361 |
18825752
|
B7-H1 negatively regulates the stimulation of activated PD-1+ T(H) cells, in co-cultures with microglia and different CNS-infiltrating APC presenting endogenously processed peptides.
|
6362 |
18825752
|
The preponderance of IFN-gamma+ versus IL-17+ T cells in the CNS of B7-H1(-/-) mice suggests that B7-H1 more selectively suppresses T(H)-1 than T(H)-17 responses in vivo.

Impact of protective IL-2 allelic variants on CD4+ Foxp3+ regulatory T cell function in situ and resistance to autoimmune diabetes in NOD mice.
|
6448 |
18941219
|
Type I diabetes (T1D) susceptibility is inherited through multiple insulin-dependent diabetes (Idd) genes.
|
6449 |
18941219
|
The protective function of the Idd3 locus is confined to the Il2 gene, whose expression is critical for naturally occurring CD4(+)Foxp3(+) regulatory T (nT(reg)) cell development and function.
|
6450 |
18941219
|
We show that resistance to T1D in NOD.B6 Idd3 congenic mice correlates with increased levels of IL-2 mRNA and protein production in Ag-activated diabetogenic CD4(+) T cells.
|
6451 |
18941219
|
We also observe that protective IL2 allelic variants (Idd3(B6) resistance allele) also favor the expansion and suppressive functions of CD4(+)Foxp3(+) nT(reg) cells in vitro, as well as restrain the proliferation, IL-17 production, and pathogenicity of diabetogenic CD4(+) T cells in vivo more efficiently than control do nT(reg) cells.
|
6452 |
18941219
|
Lastly, the resistance to T1D in Idd3 congenic mice does not correlate with an augmented systemic frequency of CD4(+)Foxp3(+) nT(reg) cells but more so with the ability of protective IL2 allelic variants to promote the expansion of CD4(+)Foxp3(+) nT(reg) cells directly in the target organ undergoing autoimmune attack.
|
6453 |
18941219
|
Thus, protective, IL2 allelic variants impinge the development of organ-specific autoimmunity by bolstering the IL-2 producing capacity of self-reactive CD4(+) T cells and, in turn, favor the function and homeostasis of CD4(+)Foxp3(+) nT(reg) cells in vivo.

We show that resistance to T1D in NOD.B6 Idd3 congenic mice correlates with increased levels of IL-2 mRNA and protein production in Ag-activated diabetogenic CD4(+) T cells.
|
6458 |
18941219
|
We also observe that protective IL2 allelic variants (Idd3(B6) resistance allele) also favor the expansion and suppressive functions of CD4(+)Foxp3(+) nT(reg) cells in vitro, as well as restrain the proliferation, IL-17 production, and pathogenicity of diabetogenic CD4(+) T cells in vivo more efficiently than control do nT(reg) cells.
|
6459 |
18941219
|
Lastly, the resistance to T1D in Idd3 congenic mice does not correlate with an augmented systemic frequency of CD4(+)Foxp3(+) nT(reg) cells but more so with the ability of protective IL2 allelic variants to promote the expansion of CD4(+)Foxp3(+) nT(reg) cells directly in the target organ undergoing autoimmune attack.
|
6460 |
18941219
|
Thus, protective, IL2 allelic variants impinge the development of organ-specific autoimmunity by bolstering the IL-2 producing capacity of self-reactive CD4(+) T cells and, in turn, favor the function and homeostasis of CD4(+)Foxp3(+) nT(reg) cells in vivo.

Our goals in this study were to investigate conditions under which T cells from NOD mice express CD40 and to determine how CD40 on autoreactive CD4 T cells contributes to their pathogenicity in T1D.
|
6491 |
18951762
|
Using CD40-positive diabetogenic T cell clones and CD4 T cells from NOD mice, we examined expression of CD40 upon activation through the TCR and costimulation through either CD28 or CD40.
|
6492 |
18951762
|
Our results indicate that CD40 expression is increased upon activation with antigen/MHC and that activation of NOD CD4 T cells through TCR/CD40 rapidly induced CD40 expression.
|
6493 |
18951762
|
Furthermore, CD40 costimulation promoted T cell proliferation to the same extent as costimulation through TCR/CD28.

Thus, costimulation through CD40 on NOD T cells contributes to their pathogenicity by providing additional pathways for activation and by inhibiting upregulation of CTLA-4 during T cell activation.

|
Natural CD4(+)CD25(+) regulatory T cells (T(reg)) show a potent immunosuppressive function and contribute to immunologic self-tolerance by suppressing potentially auto-reactive T cells.
|
6579 |
18985367
|
For example, aberrant numbers of circulating CD4(+)CD25(+) T(reg) have been seen in patients with type I diabetes, mycosis fungoides, graft-versus-host-reaction, and rheumatoid arthritis.
|
6580 |
18985367
|
Moreover, increased numbers of functionally active CD4(+)CD25(+) T(reg) have been detected in the synovial fluid of patients with rheumatoid arthritis.
|
6581 |

|
In systemic lupus erythematosus (SLE), conflicting data on the role of CD4(+)CD25(+) T(reg) in human autoimmune diseases have been presented in the literature.
|
6582 |
18985367
|
Decreased numbers of peripheral blood T(reg) have been reported by most studies on SLE patients with active disease, but non-impaired or even increased CD4(+)CD25(+) T(reg) numbers have also been described.
|
6583 |
18985367
|
Analysis of CD4(+)FoxP3(+) T(reg) in skin lesions of patients with a primarily cutaneous manifestation of the disease showed a significant reduction in cell numbers as compared to other inflammatory skin diseases, suggesting the importance of analyzing T(reg) numbers in the affected tissue.

CD4(+)Foxp3(+) regulatory T (Treg) cells originate primarily from thymic differentiation, but conversion of mature T lymphocytes to Foxp3 positivity can be elicited by several means, including in vitro activation in the presence of TGF-beta.
|
6602 |
19006694
|
We showed here that, rather than enhancing TGF-beta signaling directly in naive CD4(+) T cells, RA negatively regulated an accompanying population of CD4(+) T cells with a CD44(hi) memory and effector phenotype.
|
6603 |
19006694
|
These memory cells actively inhibited the TGF-beta-induced conversion of naive CD4(+) T cells through the synthesis of a set of cytokines (IL-4, IL-21, IFN-gamma) whose expression was coordinately curtailed by RA.

Tumor necrosis factor-related apoptosis-inducing ligand inhibits experimental autoimmune thyroiditis by the expansion of CD4+CD25+ regulatory T cells.
|
6611 |
19008314
|
There have been several reports that TNF-related apoptosis-inducing ligand (TRAIL) has the ability to suppress the development of experimental autoimmune diseases, including a mouse model of experimental autoimmune encephalomyelitis, a rabbit model of rheumatoid arthritis, type 1 diabetes mellitus, in mice and experimental autoimmune thyroiditis (EAT) in mice.

|
These CD4(+)CD25(+) T cells included both CD4(+)CD25(+)CD45RB(Low) (regulatory) and CD4(+)CD25(+)CD45RB(High) (effector) T cells.
|
6615 |
19008314
|
Our results demonstrated that mTg-immunized mice treated with TRAIL showed significant increases in the number of CD4(+)CD25(+)CD45RB(Low) T cells compared with mice immunized with mTg alone.
|
6616 |
19008314
|
CD4(+)CD25(+)CD45RB(Low) T cells expressed much higher levels of the forkhead family transcription factor, IL-10, and TGFbeta1 than CD4(+)CD25(+)CD45RB(High) T cells, and these cells can completely suppress the proliferation of the mTg-primed splenocytes in lower concentrations than the unfractionated CD4(+)CD25(+) T cells.
|
6617 |

|
CD4(+)CD25(+)CD45RB(Low) T cells were more effective at suppressing histological thyroiditis than unfractionated cells.

Exposure of APCs of NOD mice to zymosan, a fungal cell wall component that interacts with TLR2 and dectin 1, resulted in the release of significant amounts of IL-10, TGF-beta1, IL-2, and TNF-alpha.
|
6693 |
19050249

MSC spontaneously secreted IL-6, HGF, TGF-beta1 and expressed high levels of SDF-1 and low levels of VEGF, IL-1beta and PGE(2), but no EGF, insulin or glucagon.
|
6701 |

Interestingly, immunohistochemistry demonstrated that, the islets from MSC-treated rats expressed high levels of PDX-1 and that these cells were also positive for insulin staining.
|
6702 |
19062254

Type 1 diabetes (T1D), an autoimmune disease once thought to be mediated exclusively by beta cell-specific CD4+ T cells, is now recognized as one in which autoreactive CD8+ T cells play a fundamental role.

Although the PTPRC gene has a significant role in regulating CD4+ and CD8+ autoreactive T-cells, interferon-beta responsiveness, and potentially other important processes, our study does not support a role for the two tested variants of this gene in MS susceptibility in the Australian population.

Furthermore, TCR-transgenic CD4(+) T cells primed by the antigens to which they were specific in the presence of UVB-irradiated stromal cells were rendered unresponsive to the antigen restimulation, a result that was partially attributed to the induced IL-10-producing regulatory T cells.

To understand the function of Th17 cells in IDDM, we differentiated islet-reactive BDC2.5 TcR transgenic CD4(+) cells in vitro into Th17 cells and transferred them into NOD.scid and neonate NOD mice.
|
6741 |
19130584
|
Surprisingly, BDC2.5(+) cells recovered from diabetic NOD.scid mice, in comparison with those from neonate NOD mice, showed predominant IFN-gamma over IL-17 expression, indicating conversion of donor cells into Th1 cells.
|
6742 |
19130584
|
Moreover, diabetes progression in NOD.scid recipients was dependent on IFN-gamma while anti-IL-17 treatment reduced insulitic inflammation.
|
6743 |
19130584
|
These results indicate that islet-reactive Th17 cells promote pancreatic inflammation, but only induce IDDM upon conversion into IFN-gamma producers.

Interleukin 7 signaling in dendritic cells regulates the homeostatic proliferation and niche size of CD4+ T cells.

6745 |
19136960
|
Interleukin 7 (IL-7) and T cell antigen receptor signals have been proposed to be the main drivers of homeostatic T cell proliferation.
|
6746 |
19136960
|
However, it is not known why CD4(+) T cells undergo less-efficient homeostatic proliferation than CD8(+) T cells do.
|
6747 |
19136960
|
Here we show that systemic IL-7 concentrations increased during lymphopenia because of diminished use of IL-7 but that IL-7 signaling on IL-7 receptor-alpha-positive (IL-7Ralpha(+)) dendritic cells (DCs) in lymphopenic settings paradoxically diminished the homeostatic proliferation of CD4(+) T cells.
|
6748 |
19136960
|
This effect was mediated at least in part by IL-7-mediated downregulation of the expression of major histocompatibility complex class II on IL-7Ralpha(+) DCs.
|
6749 |

|
Our results indicate that IL-7Ralpha(+) DCs are regulators of the peripheral CD4(+) T cell niche and that IL-7 signals in DCs prevent uncontrolled CD4(+) T cell population expansion in vivo.

|
In addition, CD103 was found to be dispensable for T1D progression in a rapid, CD8-mediated virally-induced T1D model (the rat insulin promoter [RIP]-LCMV), suggesting that its previous efficacy in the NOD mouse model may not be related to its effect on the generation, memory conversion and/or effector function of CD8(+) or CD4(+) T cells.

A very significant fraction of islet-associated CD8 T cells in NOD mice recognize epitopes of islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP), a non-essential endoplasmic reticulum-resident protein of unclear function.
|
6787 |
19209463
|
IGRP is also a target of CD8 T cell responses in human T1D patients.
|
6788 |
19209463
|
In NOD mice, most IGRP-reactive CD8 T cells target the IGRP(206-214) epitope and are diabetogenic.
|
6789 |

|
In mice, Il2 polymorphisms control a negative feedback mechanism initiated by activated, IL2-producing autoreactive T cells in the pancreatic lymph nodes that increases the regulatory activity of CD4+CD25+ T cells.
|
6790 |
19209463
|
Not all IGRP-reactive CD8 T cell clones are pathogenic, however, and we have evidence that some of these clonotypes are actually anti-diabetogenic.
|
6791 |
19209463
|
We had previously shown that administration of altered peptide ligands (APL) targeting IGRP(206-214)-reactive CD8 T cells resulted in diabetes protection only at doses that did not delete low-avidity clones, suggesting a protective role for these clonotypes.
|
6792 |
19209463
|
Here I briefly summarize work done by us and others indicating that a prevalent subset of autoreactive CD8 T-cells in the NOD mouse are major (albeit likely dispensable) players in the pathogenesis of spontaneous autoimmune diabetes in the NOD mouse; that these T cells are targets of genetic elements affording autoimmune disease susceptibility and resistance; that they can either be diabetogenic or anti-diabetogenic according to their avidity for peptide/MHC; and that they can serve as useful targets for therapeutic intervention.

|
A profound and progressive infiltration with CD4(+), CD8(+) cells, natural killer cells, and macrophages was identified in adenovirus transduced grafts, which paralleled a decline in beta-gal expression.
|
6817 |
19224710
|
Intragraft interferon (IFN)-gamma and RANTES mRNA expression was not different between transduced and untransduced islet grafts, despite an increased expression of CC chemokine receptor 5 (CCR5).
|
6818 |
19224710
|
No significant splenocyte IFN-gamma and interleukin (IL)-4 production or serum anti-adenoviral antibodies were discovered albeit IgM antibody was detected in transduced grafts.

We demonstrated that in nonobese diabetic (NOD) mice, gal-1 therapy reduces significantly the amount of Th1 cells, augments the number of T cells secreting IL-4 or IL-10 specific for islet cell Ag, and causes peripheral deletion of beta-cell-reactive T cells.
|
6820 |
19234158
|
Preventive gal-1 therapy shifted the composition of the insulitis into an infiltrate that did not invade the islets and that contained a significantly reduced number of Th1 cells and a higher percentage of CD4(+) T cells with content of IL-4, IL-5, or IL-10.

To investigate the role of suppressor of cytokine signaling (SOCS) molecules in periodontal immunity and RANKL-mediated dendritic cell (DC)-associated osteoclastogenesis, we analyzed SOCS expression profiles in CD4(+) T cells and the effect of SOCS3 expression in CD11c(+) DCs during periodontal inflammation-induced osteoclastogenesis and bone loss in nonobese diabetic (NOD) versus humanized NOD/SCID mice.
|
6822 |
19255186
|
Our results of ex vivo and in vitro analyses showed that (i) there is significantly higher SOCS3 expression associated with RANKL(+) T-cell-mediated bone loss in correlation with increased CD11c(+) DC-mediated osteoclastogenesis; (ii) the transfection of CD11c(+) DC using an adenoviral vector carrying a dominant negative SOCS3 gene significantly abrogates TRAP and bone-resorptive activity; and (iii) inflammation-induced TRAP expression, bone resorption, and SOCS3 activity are not associated with any detectable change in the expression levels of TRAF6 and mitogen-activated protein kinase signaling adaptors (i.e., Erk, Jnk, p38, and Akt) in RANKL(+) T cells.

Interleukin-21 (IL-21)-mediated pathways in T cell-mediated disease.
|
6824 |
19261537
|
Interleukin-21 (IL-21) is produced mostly by activated CD4+ T cells and controls the differentiation and functional activity of effector T helper cells, counteracts the suppressive effects of regulatory T cells, and stimulates non-immune cells to make inflammatory mediators.
|
6825 |
19261537
|
Therefore new treatment modalities to neutralise IL-21 in vivo would be a valuable addition to the therapeutic armamentarium to combat immune-mediated inflammation.
|
6826 |
19261537
|
Here we describe the emerging role of IL-21 in the initiation and progress of the tissue-damaging inflammatory response in immune-mediated pathologies.
|
6827 |

However, it was not until the discovery that CD4(+)CD25(+) T-cells had suppressive capabilities both in vitro and in vivo that this concept regained credibility and developed into one of the most active research areas in immunology today.

Recent studies indicate that interleukin (IL)-21, a cytokine produced mostly by activated CD4+ T cells, participates in the tissue damage in various tissues, owing to its ability to regulate the function of immune and non-immune cells.
|
6918 |
19616319

6926 |
19652940
|
The ratio of CD4+/CD8+ T-cells had an elevated median value of 2.6 [quartiles 2.0; 3.1]. 61% of the vitiligo patients had a ratio higher than 2.4, which was the normal cut-off point.

Temporal analysis demonstrated that unlike CD4(+) T cells that are primed in the draining pancreatic lymph nodes, initial proliferation of transferred CD8(+) T cells was detected in the islets.
|
6932 |
19658094
|
Furthermore, ectopic expression of CD80 by beta cells accelerated the onset of insulitis mediated by beta-cell-specific CD8(+) T cells, but had no effect on CD4(+) T-cell-mediated diabetes, suggesting an antigenic interaction between beta cells and naive CD8(+) T cells.

Efficacy was associated with an expansion of bystander suppressor regulatory T cells (Tregs) recognizing the C-terminal region of GAD65 and secreting interleukin-10 (IL-10), transforming growth factor-beta (TGF-beta), and interferon-gamma (IFN-gamma).
|
6940 |
19690518
|
In addition, we found that frequency and epitope specificity of GAD65-reactive CD4(+) T cells during antigen priming at diabetes onset and Tregs detected after CT correlated.
|
6941 |
19690518
|
Consequently, NOD mice harbored significantly lower levels of GAD65-reactive CD4(+) T cells than RIP-LCMV-GP before and after treatment.

6948 |

|
Depletion of CD4(+) CD25(+) T cells in vivo did not abrogate H. polygyrus-induced T1D protection, nor did anti-IL-10 receptor blocking antibody.
|
6949 |
19752032
|
These findings suggest that infection with H. polygyrus significantly inhibits T1D in NOD mice through CD25- and IL-10-independent mechanisms and also reduces the severity of T1D when administered late after the onset of insulitis.

|
Furthermore, suppression of T1D was dependent on beta cell-specific IL-10-secreting CD4+ T cells, although the frequency of GAD65-specific FoxP3-expressing CD4+ T cells was also increased in sIA(g7)-pGAD65 dimer vaccinated NOD mice.

Idd5.1 regulates T1D susceptibility in nonobese diabetic (NOD) mice and has two notable candidate genes, Ctla4 and Icos.
|
6957 |
19783679
|
However, further support of this hypothesis is required since the Idd5.1 haplotypes of the diabetes-susceptible NOD and the resistant B10 strains differ throughout Ctla4 and Icos.
|
6958 |
19783679
|
Using haplotype analysis and the generation of novel Idd5.1-congenic strains that differ at the disease-associated Ctla4 exon 2 single-nucleotide polymorphism, we demonstrate that increased expression of liCTLA-4 correlates with reduced T1D susceptibility.
|
6959 |
19783679
|
CTLA-4(-/-) mice expressing liCTLA-4 accumulated fewer activated effector/memory CD4(+) T cells than CTLA-4(-/-) mice and the transgenic mice were partially rescued from the multiorgan inflammation and early lethality caused by the disruption of Ctla4.
|
6960 |
19788384
|
We further show that the inhibitory function is due to the induction of TGF-beta-producing CD4(+)CD25(-) islet-specific iTreg cells against the onset of T1D in NOD mice.

Disengaging the IL-2 receptor with daclizumab enhances IL-7-mediated proliferation of CD4(+) and CD8(+) T cells.
|
6962 |
19788505
|
Allograft rejection is mainly driven by the production of IL-2, which expands T cells by linking the IL-2 receptor (IL-2R) composed of three subunits: CD25, CD122 and CD132.
|
6963 |
19788505
|
Daclizumab, widely used in immunosuppression, is a humanized anti-CD25 antibody that disrupts IL-2 signaling by binding to CD25 and preventing the assembly of the high-affinity IL-2R.
|
6964 |
19788505
|
Here we show that Daclizumab, while blocking the T-cell response to IL-2, increases CD4(+) and CD8(+) T-cell proliferative response to the homeostatic cytokine IL-7.
|
6965 |
19788505
|
The IL-7R shares CD132 with the IL-2R and blocking of CD25 by Daclizumab results in the enhanced formation of the IL-7R that in turn allows IL-7 to bind more efficiently on the cell surface.
|
6966 |
19788505
|
In addition, treatment with Daclizumab delays the internalization of CD127 upon IL-7 treatment, retaining T-cell sensitivity to IL-7 for a prolonged time.

In this study, islet-specific CD4(+) T cells from BDC2.5 TCR-transgenic mice were stimulated in the absence of exogenous cytokine with iDC or mDC pulsed with high- or low-affinity antigenic peptides and examined for Treg induction.
|
6975 |
19801514

CD4(+)CD25(+) regulatory T cells (Treg), a subpopulation of CD4(+) T cells, regulate immune responses.
|
7033 |
19841877
|
During T-cell activation in vitro, a DNA demethylation agent 5-Aza-2'-deoxycytydine (DAC) can induce Foxp3 expression in CD4(+)CD25(-) Foxp3(-) cells via altering methylation status of a conserved element in the 5'-untranslated region of the Foxp3 gene.
|
7034 |
19841877
|
In the present study, a short-term treatment with a low dose of DAC significantly increased the ratios of thymic CD4(+)CD8(-) CD25(+) cells or CD4(+)CD8(-) Foxp3(+) cells to CD4(+)CD8(-) cells, and the total numbers of thymic CD4(+)CD8(-)Foxp3(+) Treg cells or CD4(+)CD8(-)CD25(+)Foxp3(+) Treg cells in the thymus in mice.
|
7035 |
19841877
|
DAC-treatment induced the Foxp3 expression and the significant demethylation of a CpG island in the first intron of the Foxp3 gene in CD4(+)CD8(-)CD25(+) cells predominantly.
|
7036 |
19841877
|
Furthermore, CD4(+)CD8(-)CD25(+) thymocytes in DAC-treated mice exhibited enhanced immunosuppressive function than those in control mice.
|
7037 |
19841877
|
Thus, the in vivo treatment with DAC can significantly promote the development of natural thymic CD4(+)CD25(+)Foxp3(+) Treg cells through Foxp3 demethylation, implicating a therapeutic application of DAC in patients suffering from autoimmune diseases.

During T-cell activation in vitro, a DNA demethylation agent 5-Aza-2'-deoxycytydine (DAC) can induce Foxp3 expression in CD4(+)CD25(-) Foxp3(-) cells via altering methylation status of a conserved element in the 5'-untranslated region of the Foxp3 gene.
|
7041 |
19841877
|
In the present study, a short-term treatment with a low dose of DAC significantly increased the ratios of thymic CD4(+)CD8(-) CD25(+) cells or CD4(+)CD8(-) Foxp3(+) cells to CD4(+)CD8(-) cells, and the total numbers of thymic CD4(+)CD8(-)Foxp3(+) Treg cells or CD4(+)CD8(-)CD25(+)Foxp3(+) Treg cells in the thymus in mice.

The non-obese diabetic mouse (NOD) is the most characterized model used to study insulin-dependent type 1 diabetes mellitus (IDDM) and Sjoögren's syndrome (SS).
|
7105 |
19934373
|
In a previous report, we found NOD.E2f1(-/-) mice show a greater progressive development to IDDM and SS compared to NOD mice.
|
7106 |
19934373
|
Our previous data indicated a progressive decrease in regulatory T cells (CD4(+)CD25(+)) and a decrease in the systemic secretion systems for insulin, and saliva was associated with the progression of IDDM and SS.
|
7107 |
19934373
|
Therefore, to define the mechanism of early-onset IDDM SS in E2F-1 deficient NOD mice required further investigation by producing E2F-1 deficient NOD/SCID mice in which the T and B cells do not develop.
|
7108 |
19934373
|
The purpose here was to analyze the essential function of the E2F-1 molecule in the development of IDDM and SS; and the dysfunction of the pancreas islet and salivary gland in the NOD background using NOD/SCID mice.
|
7109 |
19934373
|
We produced NOD/SCID.E2f1(-/-) mice using homologous recombination; determined diabetes development; measured saliva and insulin production; and performed a histological analysis.
|
7110 |
19934373
|
Therefore, we considered a deficiency in E2F-1 induces a decrease in regulatory T cells and an increase in auto-reactive T cells; however, the E2F-1 deficiency is not associated with T and B cells-independent dysfunction of pancreatic beta cell in insulin secretion.

It has long been appreciated that within the MHC, particular unusual class II genes contribute to the development of T1D in both humans and NOD mice by allowing for the development and functional activation of beta-cell autoreactive CD4 T cells.
|
7116 |
20012396
|
However, studies in NOD mice have revealed that through interactions with other background susceptibility genes, the quite common class I variants (K(d), D(b)) characterizing this strain's H2 ( g7 ) MHC haplotype aberrantly acquire an ability to support the development of beta cell autoreactive CD8 T-cell responses also essential to T1D development.

The MHC association with CD4:CD8 replicated convincingly (p = 1.4 x 10(-9)) in an independent panel of 988 individuals.
|
7151 |
20045101
|
Conditional analyses indicate that there are two major independent quantitative trait loci (QTL) in the MHC region that regulate CD4:CD8 ratio: one is located in the class I cluster and influences CD8 levels, whereas the second is located in the class II cluster and regulates CD4 levels.
|
7152 |

Functionally significant differences in expression of disease-associated IL-7 receptor alpha haplotypes in CD4 T cells and dendritic cells.
|
7164 |
20097866
|
Common genetic variants of IL-7 receptor alpha (IL-7Ralpha) have recently been shown to affect susceptibility to multiple sclerosis (MS) and type 1 diabetes, and survival following bone marrow transplantation.
|
7165 |
20097866
|
The TSLP/IL-7Ralpha interaction on DCs is known to be critical for production of thymic regulatory T cells, and reduced production of these cells in MS susceptibility haplotypes may be a basis for its association with this disease.

CD47 and signal regulatory protein (SIRP) interactions have been proposed to take part in autoimmune disease susceptibility.
|
7167 |
20138735
|
Importantly, a recent genome-wide association study for type 1 diabetes susceptibility highlighted the association of the 20p13 region comprising the SIRP cluster, where some of the SIRP proteins encode functional ligands to CD47.
|
7168 |
20138735
|
Interestingly, CD47-deficient mice show a severe reduction in the number of mature CD4(-)CD8(-) T cells, and passive transfer of these CD4(-)CD8(-) T cells is sufficient to restore immune tolerance and prevent diabetes progression.
|
7169 |
20138735
|
Together, these findings constitute an in vivo demonstration that CD47 is involved in diabetes susceptibility and controls the homeostatic regulation of CD4(-)CD8(-) T cells.

Since most of the glutamic acid decarboxylase 65 (GAD65)-specific CD4(+) T cells in the NOD mouse are tolerogenic but unable to function in an autoimmune environment, we have activated a silent, monoclonal T-regulatory cell population (GAD65(217-230)-specific CD4(+) T cells) using a soluble I-A(αβ) (g7)/GAD65(217-230)/Fcγ2a dimer, and measured the effect on the ongoing polyclonal diabetogenic T-cell process.

Impaired antiviral CD8 and CD4 T-cell responses are often associated with chronic viral infections.
|
7308 |
20565292
|
Here we demonstrate that CD103, an alpha E integrin necessary for T-cell homing and retention in the gut and other epithelia expressed by the majority of naïve CD8(+), and CD4(+)CD25(+) T cells and some DC subsets, is unnecessary for controlling T-cell responses during chronic lymphocytic choriomeningitis virus clone 13 (LCMV cl13) infection.
|
7309 |
20565292
|
T-cell analysis following viral infection showed that the primary as well as the memory CD8(+) and CD4(+) T-cell responses among CD103-sufficient and CD103-deficient mice were identical.
|
7310 |
20565292
|
Interestingly, CD103 levels on the effector CD8(+) T cells became reduced soon after virus infection, with a small proportion of cells co-expressing PD-1 and CD103.
|
7311 |
20565292
|
In contrast, although no substantial differences in the frequency and number of the CD4(+)CD25(+) cell population were seen, CD103 expression increased significantly over time in this population, correlating with viral persistence.

20720201
|
MEKK3 overexpression contributes to the hyperresponsiveness of IL-12-overproducing cells and CD4+ T conventional cells in nonobese diabetic mice.
|
7377 |
20720201
|
Aberrant p38 activation induced by various inflammatory stimuli in IL-12-overproducing cells is not due to defective MAPK phosphatase-1 induction in NOD mice.
|
7378 |
20720201
|
Deviated IKK and MAPKs activation also occurs in NOD CD4(+) Tconv cells, which is associated with higher rates of proliferation.
|
7379 |
20720201
|
All of the above evidence suggests that the signaling defects occur at the level of MAPK kinase kinase (MAK3K or MEKK).
|
7380 |
20720201
|
Further exploration shows that MEKK3, but not other MAP3Ks, is overexpressed in NOD IL-12-overproducing cells and CD4(+) Tconv cells independent of autoimmune inflammation.

CD4(+)FOXP3(+) regulatory T cells are essential for immune tolerance, and murine studies suggest that their dysfunction can lead to type 1 diabetes (T1D).
|
7383 |
20810982
|
Recently, distinct subsets of CD4(+)FOXP3(+) T cells with differing function were identified.
|
7384 |
20810982

Therefore, we evaluated whether the relative fractions of CD4(+)FOXP3(+) subsets are altered in new-onset T1D subjects.
|
7385 |
20810982

Immunotargeting of insulin reactive CD8 T cells to prevent diabetes.
|
7402 |
20850948
|
Insulin is one of the earliest targeted autoantigens in the immune destruction of insulin-producing beta cells by autoreactive CD4 and CD8 T cells in type 1 diabetes.
|
7403 |
20850948
|
In this study, we used Non-obese diabetic (NOD) transgenic T cells engineered to express MHC class I-insulin peptide complexes linked to a T cell activation component (InsCD3-ζ), to target insulin-reactive CD8 T cells.
|
7404 |
20850948
|
We showed that activated, but not naïve, InsCD3-ζ CD8 T cells killed diabetogenic insulin-reactive CD8 target cells in vitro, inducing antigen-specific cell death mediated via both the release of perforin and the Fas-Fas ligand pathway.
|
7405 |
20850948
|
Finally, in vivo, we showed that diabetes induced by adoptive transfer of insulin-reactive T cells was reduced following injection of activated InsCD3-ζ CD8 T cells.
|
7406 |
20850948
|
Thus, using this novel system we have demonstrated that InsCD3-ζ CD8 T cells can directly kill insulin-reactive CD8 T cells in vitro and by targeting insulin-specific CD8 T cells early in the course of disease alter the progression of spontaneous diabetes in vivo in NOD mice.

|
Mice receiving UA or metformin supplementation had increased CD4(+)CD8(+) subpopulations in the thymus compared to the untreated diabetic mice.
|
7410 |
20869956
|
Concanavalin A-stimulated splenic T-lymphocyte proliferation and single-positive (CD4(+) and CD8(+)) subpopulations were significantly higher in the UA-supplemented diabetic groups than in the untreated diabetic group, but lipopolysaccharide-stimulated B-lymphocyte proliferation and the CD19(+) subpopulation were not significantly different among the groups.

Our previous studies of the murine genetic locus Idd6 revealed the aryl hydrocarbon receptor nuclear translocator-like protein 2 (Arntl2) as a candidate gene for type 1 diabetes; and in Idd6 NOD.C3H congenic mice, Arntl2 upregulation is linked to decreased diabetes development. 2.
|
7421 |
20880188
|
Diabetes incidence was increased by Arntl2 mRNA interference in the congenic strain and this was associated with an increase in CD4(+) T cells and a decrease in regulatory T cells in the peripheral immune system. 4.

Naturally occurring regulatory T cells (nTregs; CD4(+)CD25(+)Foxp3(+)) are capable of suppressing the chronic inflammation observed in a variety of different animal models of autoimmune and chronic inflammatory diseases such as inflammatory bowel diseases, diabetes, and arthritis.
|
7425 |
20941602

Acquisition of regulatory function by human CD8(+) T cells treated with anti-CD3 antibody requires TNF.
|
7435 |
21038470
|
They inhibit CD4(+) T-cell proliferation by mechanisms involving TNF and CCL4, and by blocking target cell entry into G2/M phase of cell cycle but neither kill them, nor compete for IL-2.

To this end, we determined the feasibility of cloning and expanding human CD4(+) Treg specific for the type 1 diabetes autoantigens, GAD65 and proinsulin.
|
7439 |
21050716
|
Blood CD4(+) cells stimulated to divide in response to GAD65 (in three healthy individuals) or proinsulin (in one type 1 diabetic) were flow sorted into single cells and cultured on feeder cells in the presence of anti-CD3 monoclonal antibody, IL-2 and IL-4.
|

21112637
|
We examined CD4(+) and CD8(+) T cells from diabetes prone (DR(lyp/lyp)) or resistant (DR(+/+)) congenic biobreeding (BB) rats for expression of GABA(A) channels.
|
7452 |
21112637

Our results show that BB rat CD4(+) and CD8(+) T cells express α1, α2, α3, α4, α6, β3, γ1, δ, ρ1 and ρ2 GABA(A) channel subunits.
|
7453 |
21112637

Programmed death-1 (PD-1) is a co-inhibitory receptor of the CD28/CTLA-4 family which is expressed on activated T cells and inhibits T cell activation after binding to PD-1 ligands.
|
7467 |
21116786
|
Although the expression of CTLA-4, PD-1 and FoxP3, which are inhibitory molecules of activated T cells, is reduced only on STZ injected wild type (WT) mice, CD4, CD8 and regulatory T cell populations were not changed in all experimental groups.
|
7468 |
21116786
|
When splenocytes were re-stimulated in ex vivo, the production of IL-2 and IFN-γ and the T cell proliferation were increased in all STZ injected mice, but the increment rate was less in PD-1 Tg groups.
|
7469 |
21116786
|
Although more experimental evidence needs to be provided, these results suggest that ligation of PD-1 and PD-L1/2 may have an effect on macrophages as well as does T cells.

We previously described the NOD.c3c4 mouse, which is protected from type 1 diabetes (T1D) because of protective alleles at multiple insulin-dependent diabetes (Idd) genes, but develops autoimmune biliary disease (ABD) resembling primary biliary cirrhosis (PBC).
|
7473 |
21169553
|
The frequency of effector memory (CD44(+)CD62L(-)) and central memory (CD44(+)CD62L(+)) CD8 T cells is significantly increased in the intrahepatic lymphocyte fraction of NOD.ABD mice, and NOD.ABD CD8 T cells produce more IFN-γ and TNF-α, compared with controls.
|
7474 |
21169553
|
Unlike T1D where both CD4 and CD8 T cells are required for disease transfer, purified NOD.ABD CD8 T cells can transfer liver inflammation into NOD.c3c4 scid recipients, and disease transfer is ameliorated by cotransferring T regulatory cells.

To explore a novel gene therapy strategy combining immunotherapy and β cell regeneration, we constructed a non-viral plasmid encoding proinsulin (PI) and pancreatic regenerating (Reg) III protein (pReg/PI).
|
7476 |
21185938
|
Treatment with pReg/PI also restored the balance of Th1/Th2 cytokines and expanded CD4(+)CD25(+)Foxp3(+) T regulatory cells, which may attribute to the establishment of self-immune tolerance.

The CD4:CD8 ratio was reduced drastically upon LCMV infection due to an expansion of CD8 effectors but ameliorated in ATG-treated mice.
|
7479 |
21235534
|
Although the percentage of CD4(+) CD25(+) regulatory T cells (T(regs) ) within the CD4(+) population was increased significantly after ATG therapy, their frequency in the periphery was reduced dramatically and never returned to normal baseline.
|
7480 |
21235534
|
The inability of ATG treatment to cure T1D in a stringent viral model (RIP-LCMV mice) is due at least partially to the inability to maintain or increase a sufficient CD4(+) CD25(+) T(regs) frequency, in striking contrast with what was reported in the NOD model.

|
The E3 ubiquitin ligase Cbl-b regulates T cell activation thresholds and has been associated with protecting against type 1 diabetes, but its in vivo role in the process of self-tolerance has not been examined at the level of potentially autoaggressive CD4(+) T cells.
|
7488 |
21248249
|
By tracing the fate of pancreatic islet-reactive CD4(+) T cells in prediabetic 3A9-TCR × insHEL double-transgenic mice, we find that Cbl-b deficiency contrasts with AIRE or IL-2 deficiency, because it does not affect thymic negative selection of islet-reactive CD4(+) cells or the numbers of islet-specific CD4(+) or CD4(+)Foxp3(+) T cells in the periphery, although it decreased differentiation of inducible regulatory T cells from TGF-β-treated 3A9-TCR cells in vitro.

21248249
|
By tracing the fate of pancreatic islet-reactive CD4(+) T cells in prediabetic 3A9-TCR × insHEL double-transgenic mice, we find that Cbl-b deficiency contrasts with AIRE or IL-2 deficiency, because it does not affect thymic negative selection of islet-reactive CD4(+) cells or the numbers of islet-specific CD4(+) or CD4(+)Foxp3(+) T cells in the periphery, although it decreased differentiation of inducible regulatory T cells from TGF-β-treated 3A9-TCR cells in vitro.

Type 1 diabetes is the result of a breakdown in immune regulation that leads to expansion of autoreactive CD4+ and CD8+ T cells, autoantibody-producing B lymphocytes and activation of the innate immune system.

Protection against diabetes was accompanied by histone hyperacetylation in pancreas and spleen, enhanced frequency of CD4(+) CD62L(+) cells in the spleen, reduction in cellular infiltration of islets, restoration of normoglycemia and glucose-induced insulin release by beta cells.

Activation of splenic T lymphocytes derived from protected mice in vitro with pharmacological agents that bypass the antigen receptor or immobilized anti-CD3 antibody resulted in enhanced expression of Ifng mRNA and protein without altering the expression of Il4, Il17, Il18, Inos and Tnfa genes nor the secretion of IL-2, IL-4, IL-17 and TNF-α proteins.
|
7495 |
21321581
|
Consistently, expression of the transcription factor involved in Ifng transcription, Tbet/Tbx21 but not Gata3 and Rorgt, respectively, required for the transcription of Il4 and Il17, was upregulated in activated splenocytes of protected mice.

To understand better the plasticity of human Tregs in the context of type 1 diabetes, we characterized an IFN-γ-competent subset of human CD4(+)CD127(lo/-)CD25(+) Tregs.
|
7501 |
21368230
|
Purified IFN-γ(+) Tregs were assessed for suppressive function, degree of TSDR demethylation, and expression of Treg lineage markers FOXP3 and Helios.
|
7502 |
21368230
|
Naive Tregs were capable of upregulating expression of Th1-associated T-bet, CXCR3, and IFN-γ in response to IL-12.

Here, we show that the α-isoform of myosin heavy chain (α-MyHC, which is encoded by the gene Myh6) is the pathogenic autoantigen for CD4+ T cells in a spontaneous mouse model of myocarditis.

These tolerogenic pDCs convert naive anti-islet T cells into Foxp3(+) CD4(+) regulatory T cells (T reg cells) in pancreatic LNs.
|
7506 |
21458378
|
The suppression was likely to be mediated by T cells, as we found that regulatory CD4(+)CD25(+)Foxp3(+) cells were significantly increased in G/10-DC treated animals.
|
7507 |
21458378
|
In vivo, the G/10-DCs inhibited diabetogenic T cell proliferation; in vitro, they had reduced expression of costimulatory molecules and produced little IL-12/23 p40 or IL-6 but a large amount of IL-10 when compared with DCs matured in the presence of IL-4 (G/4-DC).

|
The osteoblast-specific bone forming markers osteocalcin and osteoprotegerin were decreased in TH mice, whereas osteoclast-driven bone resorption markers such as IL-6 and RANKL were significantly elevated in the bone marrow and blood of TH mice.
|
7510 |

AGEs induce the secretion of proinflammatory cytokines IL-6, TNF-α, and IL-12, but not RANTES or MIP-1α, and did not lead to MDDC maturation as demonstrated by the lack of expression of the CD83 molecule.

Foxp3(+) regulatory T cells (Tregs) originate in the thymus, but the Treg phenotype can also be induced in peripheral lymphoid organs or in vitro by stimulation of conventional CD4(+) T cells with IL-2 and TGF-β.
|
7622 |
21543717
|
Most Treg-typical transcripts were shared by NOD or B6g7 TGF-Tregs, except for a small group of differentially expressed genes, including genes relevant for suppressive activity (Lrrc32, Ctla4, and Cd73).

We have previously proposed that sequence variation of the CD101 gene between NOD and C57BL/6 mice accounts for the protection from type 1 diabetes (T1D) provided by the insulin-dependent diabetes susceptibility region 10 (Idd10), a <1 Mb region on mouse chromosome 3.
|
7628 |
21613616
|
Susceptibility to T1D was correlated with genotype-dependent CD101 expression on multiple cell subsets, including Foxp3(+) regulatory CD4(+) T cells, CD11c(+) dendritic cells, and Gr1(+) myeloid cells.

In an in vitro assay in which Tregs were induced from CD4+CD25- T cells by transforming growth factor (TGF)-β, high glucose enhanced the efficiency of CD4+CD25+Foxp3+ inducible Tregs (iTregs) induction.
|
7973 |
21983870
|
In addition, CD4+CD25- T cells from diabetic mice were more susceptible to CD4+CD25+Foxp3+ iTreg differentiation than those cells from control mice.
|
7974 |
21983870
|
These data, together with the enhanced frequency of CD4+Helios-Foxp3+ iTregs in the periphery of mice with diabetes, indicate that enhanced CD4+CD25+Foxp3+ iTreg induction also contributes to a peripheral increase iCD4+CD25+Tregs in diabetic mice.
|
7975 |
21983870
|
Our data show that hyperglycemia may alter the frequency of CD4+CD25+Foxp3+ Tregs in mice, which may result in late-state immune dysfunction in patients with diabetes.

We show that treatment of non-obese diabetic (NOD) mice with an OX40 agonistic antibody (OX86) reduced type 1 diabetes (T1D) incidence by inducing both CD4(+)CD25(+)Foxp3(+) Tregs and CD4(+)Foxp3(-) T cells expressing the latency-associated peptide (LAP).
|
7977 |
22063316
|
These OX86-induced CD4(+)Foxp3(-)LAP(+) T cells also demonstrated suppressive activity in vitro.
|
7978 |
22063316
|
Synergy resulted from an expansion of IL-10-expressing insB9:23-reactive Tregs which augmented the proportion of CD4(+) T cells with in vivo suppressive activity.

Given the role of Fas-mediated signaling in regulating effector T cell responses, we tested if pancreatic islets can be engineered ex vivo to display on their surface an apoptotic form of Fas ligand protein chimeric with streptavidin (SA-FasL) and whether such engineered islets induce tolerance in allogeneic hosts.
|
7987 |
22068235
|
Tolerance was initiated and maintained by CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells, as their depletion early during tolerance induction or late after established tolerance resulted in prompt graft rejection.
|
7988 |
22116888
|
FoxP3-expressing CD4(+) regulatory T cells (Tregs) are potential candidates to control autoimmunity because they play a central role in maintaining self-tolerance.

Here, we have reevaluated the contribution of CD28-CD80/86 costimulation in the LCMV system by use of CD80/86-deficient mice, and our results demonstrate that a disruption of CD28-CD80/86 signaling compromises the magnitude, phenotype, and/or functionality of LCMV-specific CD8(+) and/or CD4(+) T cell populations in all stages of the T cell response.
|
7991 |
22156513
|
Notably, a profound inhibition of secondary T cell immunity in LCMV-immune CD80/86-deficient mice emerged as a composite of both defective memory T cell development and a specific requirement for CD80 but not CD86 in the recall response, while a related experimental scenario of CD28-dependent yet CD80/86-independent secondary CD8(+) T cell immunity suggests the existence of a CD28 ligand other than CD80/86.
|
7992 |
22156513
|
Furthermore, we provide evidence that regulatory T cells (T(REG)s), the homeostasis of which is altered in CD80/86(-/-) mice, contribute to restrained LCMV-specific CD8(+) T cell responses in the presence of CD80/86.
|
7993 |

We tested these hypotheses by investigating whether infection with the filarial nematode Litomosoides sigmodontis prevents diabetes onset in IL-4-deficient NOD mice and whether depletion or absence of regulatory T cells, IL-10, or TGF-β alters helminth-mediated protection.
|
7994 |
22174447
|
Infections in immunocompetent and IL-4-deficient NOD mice were accompanied by increases in CD4(+)CD25(+)Foxp3(+) regulatory T cell frequencies and numbers, respectively, and helminth infection increased the proliferation of CD4(+)Foxp3(+) cells.

22174945
|
Peripheral blood mononuclear cells (PBMC) were stimulated in vitro with GAD(65).
|
7997 |
22174945
|
Frequencies of naïve, central and effector memory CD4+ and CD8+ T cells were measured, together with cytokine secretion, proliferation, gene expression and serum GAD(65) autoantibody (GADA) levels.
|
7998 |
22174945
|
Moreover, post-treatment serum GADA titres remained persistently increased in the GAD-alum arm, but did not inhibit GAD(65) enzymatic activity.
|
7999 |
22174945
|
In parallel to a GAD(65)-induced T-cell activation, our results show induction of T-cell inhibitory pathways important for regulating the GAD(65) immunity.

|
8004 |
22186414

Depletion of B2 but not B1a B cells in BAFF receptor-deficient ApoE mice attenuates atherosclerosis by potently ameliorating arterial inflammation.
|
8038 |
22238605
|
Here, we examined the development of atherosclerosis in BAFF-R deficient ApoE(-/-) mice because B2 cells but not B1a cells are selectively depleted in BAFF-R deficient mice.
|
8039 |
22238605
|
We fed BAFF-R(-/-) ApoE(-/-) (BaffR.ApoE DKO) and BAFF-R(+/+)ApoE(-/-) (ApoE KO) mice a high fat diet (HFD) for 8-weeks.
|
8040 |
22238605
|
BAFF-R deficiency in ApoE(-/-) mice was also associated with a reduced expression of VCAM-1 and fewer macrophages, dendritic cells, CD4+ and CD8+ T cell infiltrates and PCNA+ cells in lesions.

Adjuvant immunotherapy of experimental autoimmune encephalomyelitis: immature myeloid cells expressing CXCL10 and CXCL16 attract CXCR3+CXCR6+ and myelin-specific T cells to the draining lymph nodes rather than the central nervous system.
|
8044 |
22287719
|
Immature myeloid cells in dLNs expressed the chemokines CXCL10 and CXCL16 in an IFN-γ-dependent manner.
|
8045 |
22287719
|
Subsequently, CD4(+) T cells coexpressing the cognate chemokine receptors CXCR3 and CXCR6 and myelin oligodendrocyte glycoprotein (MOG)-specific CD4(+) T cells accumulated within the chemokine-expressing dLNs, rather than within the CNS.
|
8046 |
22287719
|
In addition to altering the distribution of MOG-specific T cells, adjuvant treatment suppressed development of MOG-specific IL-17.
|
8047 |
22287719
|
Thus, adjuvant immunotherapy of EAE requires IFN-γ, which suppresses development of the Th17 response, and diverts autoreactive T cells away from the CNS toward immature myeloid cells expressing CXCL10 and CXCL16 in the lymph nodes.

Insulin sensitive and resistant obesity in humans: AMPK activity, oxidative stress, and depot-specific changes in gene expression in adipose tissue.
|
8054 |
22323564
|
We previously reported that adenosine monophosphate-activated protein kinase (AMPK) activity is lower in adipose tissue of morbidly obese individuals who are insulin resistant than in comparably obese people who are insulin sensitive.
|
8055 |
22323564
|
We confirmed that AMPK activity is diminished in the insulin resistant group.
|
8056 |
22323564
|
A custom PCR array revealed increases in mRNA levels of a wide variety of genes associated with inflammation and decreases in PGC-1α and Nampt in omental fat of the insulin resistant group.
|
8057 |
22323564
|
In contrast, subcutaneous abdominal fat of the same patients showed increases in PTP-1b, VEGFa, IFNγ, PAI-1, and NOS-2 not observed in omental fat.
|
8058 |
22323564
|
Only angiotensinogen and CD4(+) mRNA levels were increased in both depots.
|
8059 |
22323564
|
Thus, adipose tissues of markedly obese insulin resistant individuals uniformly show decreased AMPK activity and increased oxidative stress compared with insulin sensitive patients.

We have investigated the role of CD40 signaling in islet-reactive, diabetogenic CD4(+) Th1 T-cell clones.
|
8097 |
22488364
|
Using multispectral flow cytometry, we showed that CD40 and CD154 are co-expressed and form complexes on the surface of activated T cells.
|
8098 |
22488364
|
We also demonstrate that activated Tcells can transactivate CD4(+) CD40(+) T cells through the CD40-CD154 pathway.
|
8099 |

We found that Dll4 pharmacological blockade induces accumulation of tDCs and CD4(+)CD25(+)FoxP3(+) regulatory T cells (T(reg) cells) in the thymic cortex.
|
8109 |
22547652
|
Anti-Dll4 treatment converts CD4(-)CD8(-)c-kit(+)CD44(+)CD25(-) (DN1) T cell progenitors to immature DCs that induce ex vivo differentiation of naive CD4(+) T cells into T(reg) cells.
|
8110 |
22547652
|
Induction of these tolerogenic DN1-derived tDCs and the ensuing expansion of T(reg) cells are Fms-like tyrosine kinase 3 (Flt3) independent, occur in the context of transcriptional up-regulation of PU.1, Irf-4, Irf-8, and CSF-1, genes critical for DC differentiation, and are abrogated in thymectomized mice.

Significantly higher Dectin-1 expression was also detected in CD4(+) T, CD8(+) T, B cells and NK cells from T2D patients compared to controls.
|
8115 |
22560862
|
In contrast, monocytes from T2D patients with poor glycemic control (HbA1c>8%) showed a diminished percentage of Dectin-1(+)/TLR2(+) cells.

Interleukin-21 receptor-mediated signals control autoreactive T cell infiltration in pancreatic islets.
|
8118 |

|
It remains unclear how interleukin-21 receptor (IL-21R) contributes to type 1 diabetes.
|
8119 |
22579473
|
Here we have shown that dendritic cells (DCs) in the pancreas required IL-21R not for antigen uptake, but to acquire the chemokine receptor CCR7 and migrate into the draining lymph node.
|
8120 |
22579473
|
Consequently, less antigen, major histocompatibility complex (MHC) class II, and CD86 was provided to autoreactive effector cells in Il21r(-/-) mice, impairing CD4(+) T cell activation, CD40:CD40L interactions, and pancreatic infiltration by autoreactive T cells.
|
8121 |
22579473
|
CD40 crosslinking restored defective CD4(+) cell expansion and CD4 independently expanded autoreactive CD8(+) cells, but CD8(+) cells still required CD4(+) cells to reach the pancreas and induce diabetes.
|
8122 |
22579473
|
We conclude that IL-21R controls both antigen transport by DCs and the crucial beacon function of CD4(+) cells for autoreactive CD8(+) cells to reach the islets.

8136 |
22596049

In contrast, during obesity DCs (human CD11c(+)CD1c(+) and mouse CD11c(high)F4/80(low)) accumulated in adipose tissue.
|
8137 |
22596049
|
In patients, the presence of CD11c(+)CD1c(+) DCs correlated with the BMI and with an elevation in Th17 cells.
|
8138 |
22596049
|
CD1c gene expression further correlated with homeostatic model assessment-insulin resistance in the subcutaneous adipose tissue of obese patients.
|
8139 |
22649557
|
Interestingly, the latter delay or protection from T1D is associated with the enhanced secretion of IL-10 rather than IFN-g by C24:0-treated CD4(+) T cells and the deviation of the islet-reactive diabetogenic T cell response.

ADMSC treatment reversed the hyperglycemia of early-onset diabetes in 78% of diabetic NOD mice, and this effect was associated with higher serum insulin, amylin, and glucagon-like peptide 1 levels compared with untreated controls.
|
8154 |
22688334
|
This improved outcome was associated with downregulation of the CD4(+) Th1-biased immune response and expansion of regulatory T cells (Tregs) in the pancreatic lymph nodes.
|
8155 |

We also observed sensitization of the Th1 differentiation machinery through co-localization of IL-2Rα, IL-4Rα, and IL-12Rβ2 subunits with GM1 positive lipid rafts, and increased STAT-4 and STAT-5 phosphorylation following membrane cholesterol enrichment.
|
8158 |
22723880
|
Antigen stimulation or CD3/CD28 polyclonal stimulation of membrane cholesterol-enriched, resting CD4 T-cells followed a path of Th1 differentiation, which was more vigorous in the presence of increased IL-12 secretion by APCs enriched in membrane cholesterol.
|
8159 |

Targeting Janus tyrosine kinase 3 (JAK3) with an inhibitor induces secretion of TGF-β by CD4+ T cells.
|
8164 |
22728763
|
Here, we show that the JAK3 inhibitor 4-(4'-hydroxyphenyl)-amino-6,7-dimethoxyquinazoline (WHI-P131) suppresses proliferation of short-term cultured NOD CD4(+) T cells through induction of apoptosis, while promoting survival of a particular population of long-term cultured cells.
|
8165 |
22728763
|
It was found that the surviving cells were not of the CD4(+)CD25(+)FoxP3(+) phenotype.

The total cell numbers of CD4(+) T cells and especially CD8(+) T cells in the spleen and pancreatic lymph node were increased in the Stat5b transgenic NOD mice.
|
8202 |
22789848

A reduction in Il2 transcription results in impaired FoxP3(+) CD4(+) Treg-cell recruitment and function, and accounts for the association between murine Il2 and type 1 diabetes (T1D).
|
8305 |
23180662
|
The progression of T1D elicits a disease-countering negative feedback regulatory loop that involves the differentiation of low-avidity autoreactive CD8(+) T cells into memory-like autoregulatory T cells in a CD4(+) Th-dependent manner.

We show that decreased IL-2 production impairs the regulatory capacity of memory-like autoregulatory CD8(+) CD122(+) T cells.
|
8307 |
23180662
|
Surprisingly, we also find that a reduction in IL-2 production capacity increases memory autoregulatory CD8(+) T-cell formation indirectly, by decreasing the development and function of FoxP3(+) Treg cells in nonobese diabetic mice.

These results illustrate a complex homeostatic interplay between IL-2, CD4(+) Th cells, FoxP3(+) CD4(+) Treg cells and autoregulatory CD8(+) T-cell memory whereby IL-2 controls the function of both Treg-cell subsets, but IL-2-potentiation of FoxP3(+) CD4(+) Treg-cell function results in the suppression of CD4(+) Th-cell activation and autoregulatory memory CD8(+) T-cell formation.

Consistent with the hypothesis that anti-clade B serpin activity blocks the serpin from binding, exposure to exogenous anti-serpin B13 mAb or endogenous anti-serpin B13 autoantibodies resulted in cleavage of the surface molecules CD4 and CD19 in lymphocytes that accumulated in the pancreatic islets and pancreatic lymph nodes but not in the inguinal lymph nodes.

One set, called type A, reacted like conventional CD4 T cells, recognizing both processed insulin protein and soluble B:9-23 peptide presented by APC.
|
8311 |

T1D is an autoimmune disorder, which involves the CD4(+) as well as CD8(+) T-cell-mediated destruction of β cells.
|
8314 |
23246831
|
In addition, the altered function of APCs and a subset of monocytes which spontaneously secrete IL-1β and IL-6 in T1D determine the abnormal expansion of Th17 as well.

Obese LGALS3(-/-) mice have increased body weight, amount of total visceral adipose tissue (VAT), fasting blood glucose and insulin levels, homeostasis model assessment of insulin resistance, and markers of systemic inflammation compared with diet-matched wild-type (WT) animals.
|
8367 |
23349493

|
Pronounced mononuclear cell infiltrate, increased expression of NLRP3 inflammasome and interleukin-1β (IL-1β) in macrophages, and increased accumulation of advanced glycation end products (AGEs) and receptor for AGE (RAGE) expression were present in pancreatic islets of obese LGALS3(-/-) animals accompanied with elevated phosphorylated nuclear factor-κB (NF-κB) p65 and mature caspase-1 protein expression in pancreatic tissue and VAT.

The data show that 1) insulin is captured and rapidly internalized by 125Tg BCRs, 2) these Ag-exposed B cells are competent to activate both experienced and naive CD4(+) T cells, 3) anergic 125Tg B cells are more efficient than naive B cells at activating T cells when Ag is limiting, and 4) 125Tg B cells are competent to generate low-affinity insulin B chain epitopes necessary for activation of diabetogenic anti-insulin BDC12-4.1 T cells, indicating the pathological relevance of anergic B cells in type 1 diabetes.

In the prevention studies, anti-CD20 plus proinsulin resulted in modest increases in Tregs in pancreatic lymph nodes and elevated levels of proinsulin-specific CD4+ T-cells that produced IL-4.
|
8375 |
23405091
|
Thus, combination therapy with anti-CD20 and either oral insulin or proinsulin does not protect hyperglycemic NOD mice, but the combination with proinsulin offers limited efficacy in T1D prevention, potentially by augmentation of proinsulin-specific IL-4 production.

Functional IL6R 358Ala allele impairs classical IL-6 receptor signaling and influences risk of diverse inflammatory diseases.
|
8471 |
23593036
|
Although a common, non-synonymous variant in the IL-6 receptor gene (IL6R Asp358Ala; rs2228145 A>C) is associated with the risk of several common diseases, with the 358Ala allele conferring protection from coronary heart disease (CHD), rheumatoid arthritis (RA), atrial fibrillation (AF), abdominal aortic aneurysm (AAA), and increased susceptibility to asthma, the variant's effect on IL-6 signaling is not known.
|
8472 |
23593036
|
We demonstrate that, although 358Ala increases transcription of the soluble IL6R isoform (P = 8.3×10⁻²²) and not the membrane-bound isoform, 358Ala reduces surface expression of IL-6R on CD4+ T cells and monocytes (up to 28% reduction per allele; P≤5.6×10⁻²²).
|
8473 |
23593036
|
Importantly, reduced expression of membrane-bound IL-6R resulted in impaired IL-6 responsiveness, as measured by decreased phosphorylation of the transcription factors STAT3 and STAT1 following stimulation with IL-6 (P≤5.2×10⁻⁷).
|
8474 |
23593036
|
Our findings elucidate the regulation of IL-6 signaling by IL-6R, which is causally relevant to several complex diseases, identify mechanisms for new approaches to target the IL-6/IL-6R axis, and anticipate differences in treatment response to IL-6 therapies based on this common IL6R variant.

Glutamic acid decarboxylase (GAD)(65) formulated with aluminium hydroxide (GAD-alum) was effective in preserving insulin secretion in a Phase II clinical trial in children and adolescents with recent-onset type 1 diabetes.
|
8476 |
23600827
|
In addition, GAD-alum treated patients increased CD4(+) CD25(hi) forkhead box protein 3(+) (FoxP3(+)) cell numbers in response to in-vitro GAD(65) stimulation.
|
8477 |
23600827
|
Regulatory T cells (CD4(+) CD25(hi) CD127(lo)) and effector T cells (CD4(+) CD25(-) CD127(+)) were further sorted, expanded and used in suppression assays to assess regulatory T cell function after GAD-alum treatment.
|
8478 |
23600827
|
GAD-alum-treated patients displayed higher frequencies of in-vitro GAD(65) -induced CD4(+) CD25(+) CD127(+) as well as CD4(+) CD25(hi) CD127(lo) and CD4(+) FoxP3(+) cells compared to placebo.
|
8479 |
23600827

Moreover, GAD(65) stimulation induced a population of CD4(hi) cells consisting mainly of CD25(+) CD127(+) , which was specific of GAD-alum-treated patients (16 of 25 versus one of 25 in placebo).
|
8480 |
23600827
|
In conclusion, GAD-alum treatment induced both GAD(65) -reactive CD25(+) CD127(+) and CD25(hi) CD127(lo) cells, but no difference in regulatory T cell function 4 years after GAD-alum treatment.

CD28-inducible transcription factor DEC1 is required for efficient autoreactive CD4+ T cell response.
|
8595 |
23878307
|
We show that the transcription factor DEC1 is highly induced in a CD28-dependent manner upon T cell activation, is involved in essential CD4(+) effector T cell functions, and participates in the transcriptional regulation of several T cell activation pathways, including a large group of CD28-regulated genes.
|

CCL22-producing CD8α- myeloid dendritic cells mediate regulatory T cell recruitment in response to G-CSF treatment.
|

23878314
|
We demonstrate in this study that the adoptive transfer of CD11c(high)CD8α(-) DCs isolated from pegylated G-CSF (pegG-CSF) recipients, but not that of other DC subtypes, enhanced the pancreatic recruitment of CD4(+)CD25(+)Foxp3(+) Tregs, which generated increased amounts of TGF-β.
|
8616 |
