Antibodies are an integral part of human immunity and their induction by vaccines has proven successful in prevention of many infectious diseases. However, some of the most dangerous pathogens of today’s world, such as HIV, influenza and malaria, evade antibody responses, both natural and vaccine-induced. A better understanding of the mechanisms by which these pathogens trigger antibody responses will be necessary for the development of more effective vaccines.
We focus on the B-cell antigen receptor, the primary receptor that controls the activation of B lymphocytes and the specificity of the antibody response. Binding of pathogens to B-cell antigen receptors leads to transduction of activation signals to B-lymphocytes, eventually leading to secretion of pathogen-specific antibodies.
