Detailed explanation-1: -B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.
Detailed explanation-2: -Memory B and T-cells are antigen-specific and, on encountering the antigen again, can mount a more rapid and effective immune response, known as the secondary immune response.
Detailed explanation-3: -Instead, memory B cells are defined as long-lived and quiescent cells that are poised to quickly respond to antigen upon recall (2–5). Both memory B cells and antibody-secreting cells (ASCs) are the product of antigen activation and, most often, interaction with cognate T helper cells.
Detailed explanation-4: -In secondary responses, on antigen rechallenge, memory B cells are activated and have at least two fates: they either differentiate into long-lived plasma cells or enter GCs to undergo rounds of population expansion, SHM and selection (Fig. 1).
