Abstract

We propose to study early molecular events leading to inflammation, focal lesion development and induction of protective immunity in Salmonella infections in mice. From very early, pre-immune stages of infection, through to host death or the induction of protective responses, bacterial components signal to host cells. We intend to concentrate on the role of lipid A in these events. To this end we have generated mutant salmonellae with defined alterations in lipid A structure and function. Using molecular biology and immunohistochemistry, we have shown that these mutants are profoundly altered in several important host-bacterial interactions, including the local induction within focal lesions of TNF alpha, IL-1 beta and inducible nitric oxide synthase. We plan to extend these studies to understand these events in molecular detail in vivo. This work will generate fundamental knowledge about the infectious disease process and may lead to novel intervention strategies. (Joint with grant D09661).
