Transgenic mouse models of type I diabetes.

Abstract

Transgenic mouse technology has gained recognition as an important tool for examining many fundamental biological questions in vivo. Recently, transgenic mouse techniques have been applied to the study of type I (insulin-dependent) diabetes. These studies have been particularly informative in elucidating 1) mechanisms whereby immune tolerance is maintained to antigens on rare specialized cells such as the pancreatic beta-cell, 2) disease susceptibility and resistance genes, and 3) potentially important immune effector mechanisms. In this article, we discuss these studies, their impact on understanding of the pathogenesis of type I diabetes, and the potential of the transgenic mouse approach for future research.
