Mouse models created to study the pathophysiology of Type 2 diabetes.

Obesity and Type 2 diabetes have become epidemics in the Western world. Understanding the pathophysiology of the disease should help in prevention and treatment of these disorders. A common theme is the presence of insulin resistance that eventually results in Type 2 diabetes. To understand the underlying mechanisms in the progression of the disease states, investigators have created mouse models by transgenic overexpression of a candidate gene or produced gene-deletion mouse models. This review will summarize many of the more appropriate models that study insulin resistance and Type 2 diabetes.
