research overview

My research focuses on a mouse model of atopic dermatitis, a condition characterized by chronic allergic inflammation of skin. Using a mouse model that mimics human atopic dermatitis developed in the laboratory of Dr. Raif Geha at Boston Children's Hospital, I tried to identify the mechanisms by which the immune sytem responds to substances introduced through the skin. Specifically, I studied the role of substances called complements in directing and changing the immune response.

research statement

Using a mouse model of atopic dermatitis, I studied the role of complement proteins and their recptors in modulating the immune response. I demonstrated that the complement proteinn C3a downregulates the Th2 response to epicutaneously introduced antigens suggesting an important role for complement proteins in T cell polarization. Furthermore, I conducted experiments to show that C3 is important for both Th1 and Th2 immune responses.
