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: -Another hallmark of memory B cells is that they display and secrete antibodies with a markedly higher affinity than those produced by primary plasma cells, as a result of somatic hypermutation and selection.
Detailed explanation-3: -B cells produce antibodies, which bind to pathogens and mark them for destruction by other immune cells. T cells kill infected host cells or help B cells produce more antibodies. Memory B and T cells persist in the body for many years, providing lifelong protection against reinfection by the same pathogen.
