memory cell
A clone of long-lived lymphocytes, formed during the primary immune response, that remains in a lymph node until activated by exposure to the same antigen that triggered its formation.

memory cell A lymphocyte capable of initiating the antibody- mediated immune response on detection of a specific antigen molecule for which it is genetically programmed. It circulates freely in the blood and lymph, and may live for years.

B memory cells Long-lived B cells that are produced after an initial exposure to an antigen and play an important role in secondary immunity. They remain in the body and facilitate a more rapid responce if the antigen is encountered again.

(Redirected from Memory cell)
Memory B cells are B cells that although activated by the immune system, they are stored inside the circulatory system for later use, for long periods of time, possibly a whole lifetime.

Their antigen receptors are surface immunoglobulins (antibodies). They recognize peptides directly and secrete antibodies by differentiating into plasma cells. They also exist as long-lived memory cells.

They go through what we were talking about earlier: program cell death or apoptosis. So you lose them. You'll save a few of them-they're memory cells-so if that organism comes in again, they can react very quickly.
