Historically, memory T cells were thought to belong to either the effector (TEM cells) or central memory (TCM cells) subtypes, each with their own distinguishing set of cell surface markers (see below). Subsequently, numerous additional populations of memory T cells were discovered including tissue-resident memory T (TRM) cells, stem memory TSCM cells, and virtual memory T cells.
