title: Increased sensitivity of prediabetic nonobese diabetic mouse to the behavioral effects of IL-1.
abstract: The nonobese diabetic (NOD) mouse is a model of spontaneous insulin-dependent diabetes mellitus (IDDM) or type I diabetes. In humans, and in animal models of IDDM, the progression of the disease is modulated by various environmental factors, particularly infectious agents. Interleukin-1 (IL-1) plays a pivotal role in the development of IDDM, and modulation of its synthesis may be a mechanism by which environmental modulation of disease progression occurs. Since various alterations at the level of the gene, number, and sensitivity of IL-1 receptors have been described in different animal models of autoimmune disease, we investigated, in the prediabetic NOD mouse, the presence of IL-1 receptors and their functional behavioral characteristics. Here we present evidence that prediabetic NOD mice exhibit a normal distribution and density of functional brain IL-1 receptors, but are more sensitive to the behavioral effects of IL-1 than the control ICR strain.
