Recent key research accomplishment: Cellular Immunity Section Identified a Polysaccharide interaction affecting activity of toll like receptors (TLRs)
Recent key research accomplishments: • Pathogenic Neisseria Section • Showed that O acetyl groups on the meningococcal group A polysaccharide are critical for induction of bactericidal antibodies • Developed a sensitive gonococcal genetic porin (Por) typing system to investigate Por specific immunity to gonorrhea
Recent key research accomplishments: • Lipopolysaccharide Section • Defined a new gene, lgtH, in the biosynthesis of meningococcal lipooligosaccharide • Found that sialylation of the terminal galactose of meningococcal LOS requires at least a trisaccharide moiety
