Stem cell featuresT cell exhaustionTcf1Exhausted CD8 T (Tex) cells are dysfunctional due to persistent antigen exposure in chronic viral infection and tumor contexts. A stem cell-like Tex (Tex-stem) subset can self-renew and differentiate into terminally exhausted (Tex-term) cells. Here, we ...
CD8+T cells. Intravenous vaccination (SNP-IV) induced a higher proportion of TCF1+PD-1+CD8+T cells as compared to subcutaneous immunization (SNP-SC). Single-cell RNA sequencing showed that SNP-IV induced stem-like genes (Tcf7,Slamf6,Xcl1) whereas SNP-SC enriched for effector genes (Gzmb...
在NSCLC和ESCC患者中,PD1-TCF1+CD8+干细胞样记忆T细胞的高表达可能与良好的预后及免疫治疗疗效有关,并且在NSCLC中与肿瘤微环境内TLSs的形成密切相关。 关键词: 肿瘤微环境 / 预后 / 三级淋巴结构 / 干细胞样记忆T细胞 Abstract: Objective To investigate the impact of PD1-TCF1+CD8+ stem-like memory ...
近日,来自瑞士巴塞尔大学的Daniel D. Pinschewer团队等在Immunity杂志上合作发表了一篇题为The alarmin interleukin-33 promotes the expansion and preserves the stemness of Tcf-1+CD8+T cells in chronic viral infection的文章,他们...

1+ cells will give rise to TCF-1+ or TCF-1—cells will be dependent on internal and external signaling. Some studies have shown that both the long (p45) and the short (p33) TCF-1 isoform are expressed by CD8 T cells that will give rise to stem-like CD8 T cells during viral ...
However, the KLRG1Hi population is terminal, largely disappearing over the ensuing weeks, whereas the Tmp cell population matures into long-term memory CD8 T cells (Kaech et al., 2003). During chronic infections or in tumors, the KLRG1Hi population of Teff (or the related effector memory RA...
