Activation of CD8+ T lymphocytes in insulin-dependent diabetes mellitus.
|
2 |
9073547
|
Insulin-dependent diabetes mellitus (IDDM) is a T-cell-mediated autoimmune disease directed against the insulin-secreting beta cells of the islets of Langerhans of the pancreas.
|
3 |
9073547
|
We have previously shown that in organ-specific autoimmune diseases, Graves' disease (GD), and IDDM, the antigen that is specific for each of these disorders (i.e., TSH receptor for GD, glutamic acid decarboxylase-65 (GAD65) for IDDM) does not activate the disease-specific CD8+ cells as fully as CD8+ cells from normal persons.
|
4 |
9073547
|
In order to identify the specific antigen responsible for triggering or maintaining autoimmunity in patients afflicted with the disease, we have studied the effects of islet (beta) cell-specific antigens GAD65, insulin, pancreatic antigen (P69), T cell epitope 69 (Tep69), and a milk-derived bovine serum albumin (BSA)-peptide-ABBOS (pre-BSA positions 157-169) on the activation of CD8+ T lymphocytes in IDDM patients.
|
5 |
9073547
|
We compared the patterns of T cells activation with those mediated by an irrelevant peptide antigen, P348 (amino-terminal region of human cardiac myosin light chain-1), and also tetanus toxoid.
|
6 |
9073547
|
We also studied the responses of CD8+ T lymphocytes to these IDDM-relevant and -irrelevant antigens in Hashimoto's thyroiditis patients (HT), rheumatoid arthritis patients (RA), and normal control subjects (N) to compare the pattern of responses in the other autoimmune diseases.
|
7 |
9073547
|
When the response of CD8+ T lymphocytes of IDDM patients to each of the IDDM-relevant antigens was compared to that of the irrelevant antigen, only GAD65 and ABBOS showed a significantly reduced activation compared to P348 and tetanus toxoid.
|
8 |
9073547
|
Moreover, CD8+ T lymphocytes of IDDM patients showed a significantly lower activation by GAD65 than those from N, HT, and RA.
|
9 |
9073547
|
In conclusion, our data suggest that CD8+ T lymphocytes of IDDM patients but not those from N, HT, and RA groups have specifically reduced potential for activation in response to GAD65 but not to insulin, P69, and Tep69, whereas ABBOS exerts a less well-defined reductive effect on the activation of CD8+ lymphocytes of IDDM patients.
|
10 |
9073547
|
Since CD8+ cells have been shown to contain suppressor activity, our data support the notion that a disease-specific defect in GAD65 autoantigenic induction of suppressor T lymphocytes may be important in the pathogenesis of IDDM.

Insulin-dependent diabetes mellitus (IDDM) develops in nonobese diabetic (NOD) mice through the destruction of the B cells in pancreatic Langerhans islets by islet autoantigen-specific T cells.
|
62 |
10912505
|
The islet autoantigen glutamic acid decarboxylase 65 (GAD65) is thought to be a major target autoantigen in IDDM.
|
63 |
11160264
|
In this study, we have investigated the use of plasmid DNA (pDNA) vaccination to elicit Th2 effector cell function in an Ag-specific manner and in turn prevent insulin-dependent diabetes mellitus (IDDM) in nonobese diabetic (NOD) mice. pDNA recombinants were engineered encoding a secreted fusion protein consisting of a fragment of glutamic acid decarboxylase 65 (GAD65) linked to IgGFc, and IL-4.
|
64 |
11160264
|
Intramuscular injection of pDNA encoding GAD65-IgGFc and IL-4 effectively prevented diabetes in NOD mice treated at early or late preclinical stages of IDDM.
|
65 |
11160264
|
This protection was GAD65-specific since NOD mice immunized with pDNA encoding hen egg lysozyme-IgGFc and IL-4 continued to develop diabetes.
|
66 |
11160264
|
Importantly, GAD65-specific immune deviation was dependent on pDNA-encoded IL-4.

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.

84 |

|
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.
|
85 |
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.
|
86 |
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.
|
87 |
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.

12672406
|
Untreated nonobese diabetic mice developed autoantibodies to insulin (IAA), but not GAD or IA-2/IA-2beta, and IAA-positive mice had increased diabetes risk (P < 0.001).

However, in this study, we demonstrate protection against disease by covaccination with a mutant B7-1 molecule (B7-1wa) that binds the negative T cell regulator CTLA-4 (CD152), but not CD28.
|
122 |

|
In vitro, the T cells of covaccinated mice had negative responses to both insulin and GAD65, and this was restored by adding blocking antibodies to transforming growth factor beta1 (TGF-beta1), suggesting a role for this cytokine.
|
123 |
16790365
|
Furthermore, vaccinated mice had increased numbers of T cells with Tr-associated markers, such as CTLA-4, Foxp3, and membrane-bound TGF-beta1.

|
A double-blind randomized Phase II trial in 70 patients (10-18 years old) with recent-onset type 1 diabetes showed significant preservation of residual insulin secretion and a GAD-specific immune response, both humoral and cell-mediated, but no treatment-related adverse events.
|

|
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.

|
Increased anti-GAD65 IgG1, serum IgA and unchanged IgG2a antibodies titers; together with an increase of IL-4, IL-10 production and a decrease of IFN-gamma production suggested possible activation of GAD65-specific Th2 immune responses.
