Research interests
The alarming increase in multidrug resistant bacterial pathogens challenge efficient treatment of common infections. A fundamental understanding of the molecular interactions driving bacterial adhesion to host, and bacterial escape from host immunity, is a key step toward the development of novel antimicrobial therapies.
We use various approaches to evaluate the adhesive properties of bacterial virulence factors, and have previously shown that S. aureus SdrD specifically with Desmoglein 1, a intercellular junction-protein, expressed by keratinocytes. We have also shown that SdrD have immune evasive properties, and increases bacterial survival in presence of host immunity in vitro and in vivo. By use of similar approach, we are evaluating other virulence factors in their adhesive, invasive and immune evasive properties.
