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 immunoglobulin (Ig) class switching of the antibody heavy chains. By substituting IgM with IgG, IgA or IgE, class switching provides antibodies with novel effect or functions without changing their antigen specificity. Our overall goal is to dissect the mechanisms by which different subsets of systemic and mucosal B cells regulate class switching in response to signals from microbial products and innate immune cells.
