而且临床试验中确实延长了部分患者生存期(有的长达5年以上),这一直是一个令人困扰的问题。 2. TCF1+ TIL subset在PD-1治疗中发挥作用 Title: Intratumoral Tcf1+PD-1+CD8+ T Cells with Stem-like Properties Promote Tumor Control in Response to Vaccination and Checkpoint Blockade Immunotherapy Pubication ...
研究报道PD-1阻断促进干细胞样CD8+T细胞增殖和向TEFF分化【6】。作者发现PD-1抑制剂确实显著增加TCF1+CD39+CD8+TM和TCF1-CD39+TEFF比例,但Ki-67的增加仅在TCF1+CD39+CD8+TM细胞。这些结果表明TCF1+CD39+CD8+TM是一种有...
Thus, our studies identify a dysfunctional T-cell state occupied by T cells reactive to SSA: a TCF1+PD-1鈥 state lacking in effector function, demonstrating that the type/specificity of tumor antigen may determine tumor-reactive T-cell differentiation.Jessica J. Roetman...
进一步通过流式确认表型发现Treg的激活表型增加(CD69、ICOS、PD-1、CD44等)(a),TCF-1的缺失会使Treg比例和数量增加(b),但是CD25表达降低。在不缺失TCF-1的CD4细胞中激活表型增加(c)。 进一步发现TCF-1 缺失的Treg表达更高水平的RORγt,TGFβRI/II和pSmad2/3,pSTAT5和p...
TCF-1 mediated a T-bet-to-Eomes transcription factor transition in Tex precursors by promoting Eomes expression and drove c-Myb expression that controlled Bcl-2 and survival. These data define a role for TCF-1 in early-fate-bifurcation-driving Tex precursor cells and also identify PD-1 as a...
Programmed cell death protein 1 (PD-1) blockade is essential in treating progressive colorectal cancer (CRC). However, some patients with CRC do not respond well to immunotherapy, possibly due to the exhaustion of CD8+ T cells in the tumor microenvironme
Intravenous vaccination (SNP-IV) induced a higher proportion of TCF1PD-1CD8 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, Klrg1, Cx3...

Consistent with the RNA-seq results, PD-1 expression at the protein level was upregulated in the Tcf7-deficient LTi cells (Figures S5A and S5B). LTi cells can be divided into CD4+ and CD4− or major histocompatibility complex (MHC) II+ or MHCII− subsets.39,40,41 We verified such...
