Nonobese diabetic (NOD) mice genetically deficient in B lymphocytes (NODJg mu(null)) are resistant to T cell-mediated autoimmune insulin-dependent diabetes mellitus (IDDM).
|
3 |
9780157
|
To initially test whether they contribute to IDDM as APC, NOD B lymphocytes were transferred into NODJg mu(null) recipients.
|
4 |
9780157
|
Hence, B lymphocytes appear to contribute to IDDM in NOD mice as APC with a preferential ability to present certain beta cell Ags such as GAD to autoreactive T cells.

|
This study has examined the MNG1 and TCO loci to determine if they are similarly predisposing the Tas1 family to PTC.
|

|
In addition, six candidate genes, RET, TRK, MET, TSHR, APC and PTEN were also excluded as susceptibility genes in Tas1 by using microsatellites that are positioned in or in close proximity to these genes.

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).
|
13 |
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.

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.

Control of beta-catenin phosphorylation/degradation by a dual-kinase mechanism.
|
17 |
11955436
|
Wnt regulation of beta-catenin degradation is essential for development and carcinogenesis. beta-catenin degradation is initiated upon amino-terminal serine/threonine phosphorylation, which is believed to be performed by glycogen synthase kinase-3 (GSK-3) in complex with tumor suppressor proteins Axin and adnomatous polyposis coli (APC).
|
18 |
11955436
|
Here we describe another Axin-associated kinase, whose phosphorylation of beta-catenin precedes and is required for subsequent GSK-3 phosphorylation of beta-catenin.

Depletion of CKIalpha inhibits beta-catenin phosphorylation and degradation and causes abnormal embryogenesis associated with excessive Wnt/beta-catenin signaling.

Our study uncovers distinct roles and steps of beta-catenin phosphorylation, identifies CKIalpha as a component in Wnt/beta-catenin signaling, and has implications to pathogenesis/therapeutics of human cancers and diabetes.

Increased nonobese diabetic Th1:Th2 (IFN-gamma:IL-4) ratio is CD4+ T cell intrinsic and independent of APC genetic background.
|
22 |
12444170
|
In this study, we demonstrate that increased IFN-gamma, decreased IL-4, and decreased IL-10 production in NOD T cells is CD4 T cell intrinsic.
|
23 |
12444170
|
NOD CD4(+) T cells purified and stimulated with anti-CD3/anti-CD28 Abs generated greater IFN-gamma, less IL-4, and less IL-10 than B6.G7 CD4(+) T cells.
|
24 |
12444170
|
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.
|
25 |
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.
|
26 |
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.

We have recently described an impaired proliferative response of CD4(+) T-cells to primary antigens in patients with insulin-dependent diabetes mellitus (IDDM) [Clin.
|
28 |
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).
|
29 |
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).
|
30 |
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).
|
31 |
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.

CD1d-reactive natural killer T (NKT) cells can rapidly produce T helper type 1 (Th1) and/or Th2 cytokines, can activate antigen-presenting cell (APC) interleukin-12 (IL-12) production, and are implicated in the regulation of adaptive immune responses.
|
33 |
14632651
|
EMCV-D resistance depends on IL-12-mediated interferon-gamma (IFN-gamma) production.
|
34 |
14632651
|
We propose that CD1d-reactive T cells respond to early immune signals and function in the innate immune response to a physiological viral infection by rapidly augmenting APC IL-12 production and activating NK cells.

As regulators of T cell activation, antigen-presenting cells (APC) modulate peripheral tolerance and hence contribute to the immune dysregulation characteristic of insulin-dependent diabetes mellitus (IDDM).
|
39 |

|
As costimulatory molecules have been shown to be NF-kappa B responsive, we examined the expression of these markers on NOD APC.
|
40 |
15114673
|
Both B cells and BMDC expressed elevated levels of CD80 and CD40.
|
41 |
15114673
|
Therefore, hyperactivation of NF-kappa B and increased expression of CD80 and CD40 by NOD B cells and BMDC may be a contributing factor in the selection of effector T cells observed in IDDM.

Beta-catenin is a transcriptional co-factor in the Wnt signalling pathway that is regulated in this fashion.
|
43 |

|
Inactivating mutations in the adenomatosis polyposis coli (APC) gene, which encodes a carrier protein for beta-catenin, or stabilizing mutations in beta-catenin itself, frequently occur in human tumours.
|
44 |
16342409
|
CK2 and the monomeric serine-threonine kinase GSK3 have opposing actions on beta-catenin: GSK-3 phosphorylation of the N-terminus of beta-catenin promotes degradation; while phosphorylation by CK2 in the armadillo repeat protein interaction domain protects it.
|
45 |
16342409
|
Beta-catenin is overexpressed in mammary tumours occurring in mice transgenic for CK2 or a dominant negative form of GSK3, and also in mammary tumours arising following treatment with the environmental carcinogen DMBA.
|
46 |
16556076
|
Although the prominent role of GSK-3 in the adenomatous polyposis coli (APC)-beta-catenin destruction complex implies that inhibition of GSK-3 could possibly lead to tumor promotion through the activation of beta-catenin, several recent studies have shed new light on the activity of GSK-3 in cancer and provide insight into the molecular mechanisms by which it regulates tumor cell proliferation and survival of multiple human malignancies.

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.
|
48 |
16709812
|
Transfer of prototypic CD4+CD25+ regulatory T cells also prevented diabetes in NTX-NOD mice; however, the induction of these cells by oral insulin in euthymic mice depended on the integrity of TCRgammadelta IEL.

In the present study we prospectively analyzed the serial effects of androgen-replacement therapy on both the distribution of peripheral blood lymphocytes, monocytes and dendritic cells as well as on the production of interleukin (IL)-1beta, IL-6 and tumor necrosis factor alpha (TNFalpha) inflammatory cytokines by circulating monocytes and CD33 myeloid, CD16 and plasmacytoid dendritic cell subsets, the most potent antigen-presenting cells (APCs) in type-2 diabetic men with partial androgen deficiency.

Our results show for the first time that testosterone-replacement therapy is associated with a reduction or complete abrogation of spontaneous ex vivo production of IL-1beta, IL-6 and TNFalpha by APCs.

Deficiency in NOD antigen-presenting cell function may be responsible for suboptimal CD4+CD25+ T-cell-mediated regulation and type 1 diabetes development in NOD mice.

CD4(+)CD25(+) regulatory cells play a crucial role in controlling various autoimmune diseases, and a deficiency in their number or function could be involved in disease development.
|
53 |
16804081
|
The current study shows that NOD mice had fewer CD4(+)CD25(+) regulatory cells, which expressed normal levels of glucocorticoid-induced tumor necrosis factor receptor and cytotoxic T-lymphocyte-associated antigen-4.
|
54 |
16804081
|
We have also found that NOD CD4(+)CD25(+) cells regulate poorly in vitro after stimulation with anti-CD3 and NOD APCs in comparison with B6 CD4(+)CD25(+) cells stimulated with B6 APCs.
|
55 |
16804081
|
Surprisingly, stimulation of NOD CD4(+)CD25(+) cells with B6 APCs restored regulation, whereas with the reciprocal combination, NOD APCs failed to activate B6 CD4(+)CD25(+) cells properly.
|
56 |
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.
|
57 |
16804081
|
These data suggest that the failure of NOD APCs to activate CD4(+)CD25(+) regulatory cells may play an important role in controlling type 1 diabetes development in NOD mice.

To identify some of these recessive alleles, we crossed TNF-alpha-NOD mice to diabetes-resistant congenic NOD mice having protective alleles at insulin-dependent diabetes (Idd) loci that control spontaneous T1D at either the preinsulitis (Idd3.Idd5) or postinsulitis (Idd9) phases.

Lack of protection was not at the level of T cell priming, the efficacy of islet-infiltrating APCs to present islet peptides, nor the ability of high levels of CD4+ Foxp3+ T cells to accumulate in the islets.

APC activation restores functional CD4(+)CD25(+) regulatory T cells in NOD mice that can prevent diabetes development.

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.
|
70 |
19050249
|
Zymosan treatment induced suppression of T1D was associated with an increase in the L-selectin(high) T cell frequencies and enhanced suppressor function of CD4(+)CD25(+) T regulatory cells.
|
71 |
19050249
|
Further, activation by anti-CD3-Ab induced larger amounts of TGF-beta1 and/or IL-10 production by CD4(+)CD25(+) and CD4(+)CD25(-) T cells from zymosan-treated mice.

We attempt to induce ovarian-specific tolerance via transgenic expression of the MATER antigen on potentially tolerogenic antigen-presenting cells (APC), which typically present antigen via the major histocompatibility complex (MHC) class II molecule.
|
76 |
21447630
|
We hypothesize that expression of MATER in a MHC class II-dependent manner on APC can mediate induction of ovarian tolerance.
|
77 |
21447630
|
Transgenic expression of MATER in APC can induce antigen-specific tolerance with a significant reduction in ovarian autoimmunity.
|
78 |
21447630
|
As a known autoantigen in the human APS1 (autoimmune polyglandular syndrome type 1), which is associated with POI, MATER may represent a relevant target for future diagnostic and therapeutic clinical interventions.

Here, we show that human mesenchymal stem/stromal cells (hMSCs) and tumor necrosis factor-α-stimulated gene 6 (TSG-6), a protein produced by hMSCs in response to signals from injured tissues, delayed the onset of spontaneous autoimmune diabetes in NOD mice by inhibiting insulitis and augmenting regulatory T cells (Tregs) within the pancreas.
