Memory T cell - Wikipedia
WEBLifetime overview. Memory T cells undergo different changes and play different roles in different life stages for humans. At birth and early childhood, T cells in the peripheral blood are mainly naïve T cells. [10] Through frequent antigen exposure, the population of memory T cells accumulates.

CD8 + T-Cell Memory: The Why, the When, and the How
WEBVirtual memory T cells (Tvm cells), otherwise known as memory phenotype (MP) cells, are a population of antigenically naive CD8 + T cells that comprise ∼5%–15% of total circulating CD8 + T cells and express markers of conventional memory T cells (e.g., high levels of CD44 and CD122).
