Detailed explanation-1: -B cells secrete antibodies that contribute to tissue injury via multiple mechanisms. In addition, B cells contribute to disease pathogenesis in autoimmunity and alloimmunity by presenting antigens as well as providing costimulation and cytokines to T cells.
Detailed explanation-2: -Effector B cells can begin secreting antibody while they are still small lymphocytes, but the end stage of their maturation pathway is a large plasma cell (see Figure 24-7B), which continuously secretes antibodies at the astonishing rate of about 2000 molecules per second.
Detailed explanation-3: -Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin, or antibody. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.
