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. Activated memor [..]

Long-lived lymphocyte among the clone of cells generated when a foreign antigen is encountered. If the same antigen is encountered again, the memory cells quickly divide and give rise to another clone [..]

 T and B cells that control the ability of the immune system to remember a certain invader and prevent it from being able to cause infection in the future

a T or B cell that has been exposed to a specific invading organism and remembers the organism. Memory cells help the immune system respond faster when they encounter invading organisms for the second time.

A group of cells that help the body defend itself against disease by remembering prior exposure to specific organisms (viruses or bacteria). Therefore, they are able to respond quickly when those organisms threaten the body repeatedly. There are memory T cells and memory B cells.
