B Cell Biology

 Research group

Group Leader

Andrea Cerutti (ICREA Professor)

In the B Cell Biology research group we take advantage of different cellular, histological and molecular techniques to address basic questions related to the regulation of B cell activation and antibody production. B cells are a type of lymphocyte whose main function is to fight infections by producing antibodies. Our research group is especially interested in the class switching of the immunglobulin (Ig) heavy chain. By substituting IgM with IgG, IgA or IgE, class switching provides antibodies with novel effector functions without changing their antigen specificity. Our overall goal is to dissect the mechanisms by which different subsets of systemic or mucosal B cells regulate class switching and antibody production in response to signals from microbial products and the innate immune system.
