Web4.2.4 Memory T cells (T m cells) Memory T cells are antigen-specific T cells that remain long-term after an infection has been eliminated. The memory T cells are quickly converted into large numbers of effector T cells upon reexposure to the specific invading antigen, thus providing a rapid response to past infection. po olmakWebCD8 T cells comprising the memory pool display considerable heterogeneity, with individual cells differing in phenotype and function.
