These cells develop inside germinal centers of the secondary lymphoid organs. Memory B cells circulate within the blood stream in a quiescent state, typically for many years. Their perform is to memorize the traits of the antigen that activated their dad or mum B cell during initial infection such that if the memory B cell later encounters the identical antigen, it triggers an accelerated and strong secondary immune response. Memory B cells have B cell receptors (BCRs) on their cell membrane, equivalent to the one on their mother or father cell, that permit them to recognize antigen and mount a specific antibody response. In a T-cell dependent improvement pathway, na飗e follicular B cells are activated by antigen-presenting follicular B helper T cells (TFH) through the initial infection, or major immune response. B cells may also be activated by binding overseas antigen within the periphery the place they then move into the secondary lymphoid organs.
