Autoimmune insulitis and diabetes in the absence of antigen-specific contact between T cells and islet beta-cells.

Abstract excerpt

Autoimmune diabetes develops following recognition of organ-specific antigens by T cells. The disease begins with peri-islet infiltration by mononuclear cells, proceeds with insulitis and becomes manifest with destruction of insulin-producing islet beta-cells. T cells are necessary to induce insulitis and diabetes, but it is not clear by what mechanisms they can do so, i. e. whether the T cells need to make...
