Antibodies and their effector functions

This lecture covers the structure and function of antibodies, including their diverse effector functions such as neutralization of microbes, complement activation, opsonization, and antibody-dependent cell-mediated cytotoxicity. It explains the process of antibody binding to antigens, the production of different antibody isotypes, and the role of Fc receptors in mediating effector functions. The lecture also discusses the mechanisms of antibody-mediated clearance of helminths and the importance of antibody diversity and affinity maturation in the immune response.
