RESEARCH

The research objectives of the Zhong lab are to understand the mechanisms of inflammatory diseases so that intervention and prevention strategies can be developed. We have been using the upper genital tract pathology induced by lower genital tract infection with chlamydial organisms as a model to map chlamydial virulence factors and protective antigens and to determine host pathways/effectors involved in either pathogenesis or protective immunity. 

Specific ongoing projects include: 1) Using proteomics and biochemical approaches for systematically identifying and characterizing chlamydial pathogenic and protective determinants. 2) Understanding the molecular mechanisms of chlamydial interactions with hosts so that both chlamydial and host factors can be identified as targets for attenuating chlamydial pathogenicity and/or candidates for preventing chlamydial infection and diseases. 3) Investigating the roles of co-infection and vaginal microbiome and metabolome in chlamydial pathogenesis. 4) Transforming chlamydial organisms for delivering mucosal vaccines. 5) Screening for anti-fibrosis agents/approaches.
