Extreme Th1 bias of invariant Valpha24JalphaQ T cells in type 1 diabetes.

Type 1 diabetes (insulin-dependent diabetes mellitus, IDDM) is a disease controlled by the major histocompatibility complex (MHC) which results from T-cell-mediated destruction of pancreatic beta-cells. The incomplete concordance in identical twins and the presence of autoreactive T cells and autoantibodies in individuals who do not develop diabetes suggest that other abnormalities must occur in the immune system for disease to result. We therefore investigated a series of at-risk non-progressors and type 1 diabetic patients (including five identical twin/triplet sets discordant for disease). The diabetic siblings had lower frequencies of CD4-CD8- Valpha24JalphaQ+ T cells compared with their non-diabetic sibling. All 56 Valpha24JalphaQ+ clones isolated from the diabetic twins/triplets secreted only interferon (IFN)-gamma upon stimulation; in contrast, 76 of 79 clones from the at-risk non-progressors and normals secreted both interleukin (IL)-4 and IFN-gamma. Half of the at-risk non-progressors had high serum levels of IL-4 and IFN-gamma. These results support a model for IDDM in which Thl-cell-mediated tissue damage is initially regulated by Valpha24JalphaQ+ T cells producing both cytokines; the loss of their capacity to secrete IL-4 is correlated with IDDM.[1]
