Abstract

The Nonobese Diabetic mouse (NOD mouse) is an established model of autoimmune diabetes mellitus. While all colonies of NOD mice are derived from a single diabetic female detected during the breeding of a cataract-prone strain of mice, some of the dispersed colonies have been separated for many generations and express varying levels of diabetes. It is unclear to what extent this is due to environmental factors such as diet factor or a result of the varied origins of the colonies. Here we compare the incidence of diabetes and severity of insulitis in two divergent lines of NOD mice that differ in incidence of disease. but are maintained in the same environment. F1 crosses were performed and the progeny found to express the disease incidence of the low incidence line. This finding is consistent with either a dominant resistance gene( s) being responsible for reduced penetrance of disease or a transmissible environmental agent reducing the severity of the autoimmune process.
