In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centers of the secondary lymphoid organs. Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. Their function is to … See more T cell dependent mechanisms In a T-cell dependent development pathway, naïve follicular B cells are activated by antigen presenting follicular B helper T cells (TFH) during the initial infection, or primary See more Upon infection with a pathogen, many B cells will differentiate into the plasma cells, also called effector B cells, which produce a first wave of protective antibodies and help clear infection. … See more Memory B cells can survive for decades, which gives them the capacity to respond to multiple exposures to the same antigen.
