Research Summary

In order to survive, bacteria must quickly respond to changes in the surrounding environment. We are interested in how diverse environmental stimuli promote changes in conserved microbial structures found on the surface of pathogenic bacteria. Currently, our laboratory focuses on the remodeling of lipopolysaccharides or LPS. LPS, also referred to as endotoxin, is the major surface component of Gram-negative bacteria and represents one of the microbial molecular signals responsible for activation of the host innate immune system. Our goal is to identify and characterize the molecular mechanisms necessary for the remodeling of LPS, and to determine how alteration of LPS contributes to evasion of the innate immune response during infection. Several pathogenic bacteria are under investigation in our laboratory including Vibrio cholerae, Campylobacter jejuni, Helicobacter pylori, Salmonella typhimurium, and pathogenic strains of Escherichia coli. Understanding how bacteria remodel their cell surface is of fundamental importance and may yield new therapeutic strategies for intervention in bacterial infections.
