B lymphocytes are the<unk> s of the immune system that make antibodies to invade pathogens like viruses. They form<unk> <unk> s that remember the same pathogen for faster antibody production in future infections. In immunology, a<unk>  (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These<unk> s develop within germinal centers of the secondary lymphoid organs.<unk> s circulate in the blood stream in a quiescent state, sometimes for decades. Their function is to<unk> ze the characteristics of the antigen that activated their parent B<unk>  during initial infection such that if the<unk>  later encounters the same antigen, it triggers an accelerated and robust secondary immune response.<unk> s have B<unk>  receptors (BCRs) on their<unk>  membrane, identical to the one on their parent<unk> , that allow them to recognize antigen and mount a specific antibody response.
