memory cells

1 See lymphocyte.
2 T and B lymphocytes that mediate immunological memory. They are believed to retain information that permits a subsequent antigenic challenge to be followed by a more rapid efficient immunological reaction than that seen with the first exposure.

memory cells

B lymphocytes that retain information about previous challenge, as by infective organisms, so that antibodies can be more rapidly produced in response to a subsequent infection with the same agent.
