CD8 Positive Memory T-Lymphocyte
cd8 positive memory t-lymphocyte
"T lymphocytes that are derived from naïve CD8 expressing T cells that have been primed through antigen exposure, followed by a cycle of proliferation (expansion) and apoptosis (contraction), that yields a long-lasting population of highly antigen-specific memory cells. These cells can be identified by the presence of CD8 and the absence of CD45RA molecules on their surface."
