Abstract
Hyperexpression of major histocompatibility complex (MHC) molecules by islet cells is a prominent, early feature of islet pathology in insulin-dependent diabetes mellitus and concomitant with beta-cell failure after exposure of islets to specific cytokines or viruses. The transgenic expression of a class I MHC gene (H-2Kb) in the beta-cells of either syngeneic or allogeneic mice leads to beta-cell failure by a nonimmune mechanism. Several class II MHC transgenes, with one exception, have the same effect, but the expression of other transgenes that have products that are membrane proteins is not necessarily detrimental. Class I MHC molecules have been shown to interact directly with other mem..
