memory B cell
Quick Summary
Memory B cells are a type of lymphocyte crucial for acquired immunity. When the body encounters a foreign substance, or antigen, B cells can differentiate into plasma cells that produce antibodies. These antibodies neutralize or destroy the antigen. Other B cells, however, become memory B cells. These cells provide the immune system with long-lasting memory, allowing for a faster and more effective response if the same pathogen is encountered again. This secondary response is led by memory cells, which rapidly divide to create more antibody-producing cells and a new generation of memory cells.123

immune systemActivation of T and B lymphocytes…by clonal selection—effector cells and memory cells. Effector cells are the relatively short-lived activated cells that defend the body in an immune response. Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and helper T cells, which carry out cell-mediated responses.

immune systemActivation of B cells…B cells that are called memory cells, however, encounter antigen in the germinal centres—compartments in the lymphoid tissues where few T cells are present—and are activated in a different way. Memory cells, especially those with the most effective receptors, multiply extensively, but they do not secrete antibody. Instead, they remain…
