Research Interest

Environmental factors, such as viral infections, are proposed to damage pancreatic beta-cells and confer risk for autoimmune diabetes pathogenesis. Encephalomyocarditis virus (EMCV) is a positive single-stranded RNA picornavirus that induces diabetes in genetically susceptible mice. EMCV-induced diabetes is associated with macrophage activation and the expression of pro-inflammatory mediators such as interleukin-1 (IL-1beta) and nitric oxide (a product of inducible nitric oxide synthase – iNOS). We have recently identified the chemokine receptor CCR5 as a required signaling receptor for EMCV-stimulated inflammatory gene induction (iNOS, IL-1beta, and COX-2) in macrophages. The CCR5-dependent signaling mechanisms that regulate macrophage responses to virus infection is currently being examined.
