01

Overview

CD8-positive effector memory T cells (CD8+ Tem) are a subset of memory T lymphocytes that provide rapid immune protection against previously encountered antigens. They are characterized by their ability to quickly exert effector functions, such as cytotoxicity and cytokine production, upon re-exposure to antigen. CD8+ Tem cells are identified by their CD45RA− CCR7− phenotype and their presence in blood and peripheral tissues. They play a critical role in defense against intracellular pathogens and tumor surveillance.
