Our understanding of protective immunity comes mainly from studies of lymphocytes in the blood and lymphoid tissues, such as the spleen and lymph nodes. It is generally thought that naive CD4+T cells proliferate following an encounter with microbial antigen, then differentiate into memory cells that produce anti-microbial lymphokines. Following the encounter, the memory T cells retreat into lymphoid tissues where they remain ready to mount a response should the same antigen recur.
