Standard name GSE16522_MEMORY_VS_NAIVE_CD8_TCELL_DN
Systematic name M3659
Brief description Genes down-regulated in comparison of rested memory CD8 T cells from pmel-1 mice versus rested naive CD8 T cells from pmel-1 mice.
Full description or abstract Effector cells for adoptive immunotherapy can be generated by in vitro stimulation of naïve or memory subsets of CD8+ T cells. While the characteristics of CD8+ T cell subsets are well defined, the heritable influence of those populations on their effector cell progeny is not well understood. We studied effector cells generated from naïve or central memory CD8+ T cells and found that they retained distinct gene expression signatures and developmental programs. Effector cells derived from central memory cells tended to retain their CD62L+ phenotype, but also to acquire KLRG1, an indicator of cellular senescence. In contrast, the effector cell progeny of naïve cells displayed reduced terminal differentiation, and, following infusion, they displayed greater expansion, cytokine production, and tumor destruction. These data indicate that effector cells retain a gene expression imprint conferred by their naïve or central memory progenitors, and they suggest a strategy for enhancing cancer immunotherapy.
