Treg于1995年被发现，标志为CD3+CD4+CD25+Fox-p3+[4]。Treg细胞主要分泌TGF-β、IL-10等，具有免疫抑制功能。Treg细胞主要参与免疫耐受和免疫调节，确保免疫系统对外来抗原做出适当的应答，也避免过度的免疫反应导致自身免疫病和过度炎症反应，维持免疫系统对自身组织的耐受性，有助于细胞或器官移植。Tfh定位于
Treg cells play a pivotal role in suppressing allograft rejection but their presence in tumours hamper antitumour immunity. Here authors show that T cells, in which Setdb1 is genomically deleted, give rise to Treg cells that prevent allograft rejection but don’t compromise the antitumour immune...
尽管这些效应细胞的诱导通常由“辅助”CD4+T细胞促进,但这一过程可能会受到CD4+FOXP3+调节性T细胞(Treg细胞)的抑制。也就是说,CD4+T细胞既能增强也能抑制肿瘤免疫。 最近的研究表明,常规的Treg细胞可能不是在逐渐生长的肿瘤中存在的唯一免疫抑制性 CD4+T...
Wang等人在研究实体瘤内浸润的Treg时发现乳腺癌患者肿瘤浸润性CD4+Treg和外周eTreg的表型和TCR谱系高度重叠。因此,基于于外周血中不同的CD4+Treg亚群对四种细胞因子的反应性,他们将TME中浸润的Treg分为三类亚群,并提出了一个细胞因子信号指数(CSI)。(doi:10.1038/s41590-019-0429-7) Nat Immunol. (2) 同样对TME...
癌症免疫疗法的理想结果是产生能够破坏肿瘤的肿瘤特异性CD8+细胞溶解T细胞(CTL),虽然这些效应细胞的诱导通常是由“辅助”CD4+ T细胞促进的,但这一过程可以被CD4+FOXP3+调节性T(Treg)细胞抑制【1】。最近研究发现,常规Treg细胞可能不是渐进性生长的肿瘤中...
After activating TLR8 signal of CD4 Tregs, the proliferation level of naive CD4 T cells was higher than that of the control group. At the same time, the expression levels of eight genes and five proteins related to glucose metabolism in CD4 Treg cells with TLR8 activated were decreased and...

近日,来自美国加州大学的Chun Jimmie Ye和Lawrence Fong研究组在Cell杂志上发表题为Intratumoral CD4 T Cells Mediate Anti-tumor Cytotoxicity in Human Bladder Cancer的文章,发现在人类膀胱癌中,细胞毒性CD4+T细胞的富集水平要高于CD8+T细胞,并且,这些细胞可以有效杀伤自身肿瘤细胞。 首先,作者招募了7位罹患已发生肌肉...
