Major Research Theme
| We work on the structure and function of Clostridium difficile toxins. These protein exotoxins are among the class of enterotoxins, and they are the main virulence factor for this pathogen , the cause of pseudomembranous colitis. We are trying to elucidate the signal transduction pathways in mammalian enterocytes exposed to toxins A and B of C. difficile. The toxin receptors are surface proteins that help internalize the toxins. Toxin action involves a profound effect on mitocondrial function and activation of protein kinase c.We have also identified a membrane protein that serves as a receptor for C difficie toxins and facilitates cell binding /internalization. |
