We investigate molecular mechanisms of B cell activation that regulate humoral immunity and pathogenesis of B cell-mediated diseases. B cells migrate in and out of circulation and lymphoid tissues, and respond to environmental cues by recognizing antigens and engaging with other components of the immune system. This requires them to undergo considerable morphological, molecular and cytoskeletal reorganization. Dynamic remodeling of the B cell membrane and the actin cytoskeleton facilitates subcellular organization of key signaling proteins, enabling B cells to accomplish their various functions. We employ high resolution live cell imaging, quantitative systems biology methods and genetic knockouts in mice to investigate the role of membrane-cytoskeleton remodeling proteins in regulating B cell function. We have discovered that Ezrin, a member of the Ezrin-Radixin-Moesin (ERM) family of membrane-cytoskeleton linkers, regulates multiple facets of B cell function, such as proliferation, differentiation, migration, and antibody production. We recently discovered that Ezrin plays and important role in regulating B cell autoimmunity, inflammation and cancer. We are currently investigating the molecular mechanims underlying these diverse functions of Ezrin in B cell immunity and pathogenesis.

In other words ...

B lymphocytes are a type of blood cell that perform a very important task, which is to make antibodies that clear infections. In my lab we study how activation signals are transmitted inside B cells, so that we can design better ways to protect ourselves. Under certain circumstances, B cells either grow too much or make antibodies against our self proteins. This can lead to B cell cancers and diseases such as lupus. We are also exploring aspects of B cell function that can be targeted to develop new treatment strategies against these diseases.
