Mice bearing targeted gene mutations that affect insulin receptor (Insr) function have contributed important new information on the pathogenesis of type 2 diabetes. Whereas complete Insr ablation is lethal, conditional mutagenesis in selected tissues has more limited consequences on metabolism. Studies of mice with tissue-specific ablation of Insr have indicated that both canonical (e.g. muscle and adipose tissue) and noncanonical (e.g. liver, pancreatic beta-cells, and brain) insulin target tissues can contribute to insulin resistance, albeit in a pathogenically distinct fashion. Furthermore, experimental crosses of Insr mutants with mice carrying mutations that affect insulin action at more distal steps of the insulin signaling cascade have begun to unravel the genetics of type 2 diabetes. These studies are consistent with an oligogenic inheritance, in which synergistic interactions among few alleles may account for the genetic susceptibility to diabetes. In addition to mutant alleles conferring an increased risk of diabetes, these studies have uncovered mutations that protect against insulin resistance, thus providing proof-of-principle for the notion that certain alleles may confer resistance to diabetes.
