Analysis of MHC class II presentation of particulate antigens of B lymphocytes.


To generate Ab responses to most protein Ags, B cells must first degrade proteins in endocytic compartments and then display antigenic peptides bound to MHC class II molecules. T helper lymphocytes recognize these complexes and stimulate the B cell to synthesize Ab. Although Ab play a key role in host defense against bacteria, it is believed that B cells… (More)
