Hiding in Plain Sight: Virtually Unrecognizable Memory Phenotype CD8+ T cells

Le résumé fourni par la source

Virtual memory T (TVM) cells are a recently described population of conventional CD8+ T cells that, in spite of their antigen inexperience, express markers of T cell activation. TVM cells exhibit rapid responsiveness to both antigen-specific and innate stimuli in youth but acquire intrinsic antigen-specific response defects in the elderly. In this article, we review how the identification of TVM cells necessitates a re-evaluation of accepted paradigms for conventional memory T (TMEM) cells, the potential for heterogeneity within the TVM population, and the defining characteristics of TVM cells. Further, we highlight recent literature documenting the development of TVM cells as a distinct CD8+ T cell lineage as well their biological significance in the context of disease.
