以DC为基础的疫苗接种是另一种治疗方法,其基础是在体外将单核细胞来源的DC暴露于肿瘤抗原(肿瘤裂解物或肿瘤相关抗原- TAAs),并伴随刺激信号(GM-CSF, IL-4, TNF-α),当引入患者体内时触发抗肿瘤反应。几年前,尽管DC疫苗具有安全性和耐受性,但未能改善HCC患者的结局。然而,AFP负载DC能够刺激特异性的细胞毒性T淋...
我们用流式细胞术进一步鉴定了这群活化T细胞的流式表型为CCR7−CD27−CD45RA+CD127lo,即为终末效应记忆性T细胞(terminal effector memory T cells, TEMRA),该群细胞与不良预后密切相关。 综合各因素来看,Cluster 1患者的1年生存...

Positive staining (normal):T cells (25-35% of mature peripheral T cells, most cytotoxic T cells, CD4/CD8+ thymocytes); NK cells (30%-which are also CD3 negative); cortical thymocytes (70-80%), epidermotrophic lymphocytes in mycosis fungoides (AJSP 2002;26:450) Micro images:lymphoepitheli...
Combined agonist stimulation of the TNFR costimulatory receptors 4-1BB (CD137) and OX40(CD134) has been shown to generate supereffector CD8 T cells that clonally expand to greater levels, survive longer, and produce a greater quantity of cytokines compared to T cells stimulated with an agonist...
调节性T细胞在4T1和4T07肿瘤中的频率相似,而传统的CD4 细胞在4T1肿瘤中比4T07更丰富。相反,4T07原发性肿瘤含有的CD8 T细胞的比例更高(图3b,左下图)。 图3 休眠期乳腺癌中出现CD39 PD-1 CD8 T细胞 Female BALB/c mice were injected with 105 4T1or 4T07 cells in the mammary fat pad and primary ...
cells would be of great interest in the future1,2. Cancer stem cells (CSCs) are characterized by the potential to self-renew, high tumorigenicity in nude mice and the ability to efficiently reconstitute all tumor subpopulations and primary tumor phenotype3,4,5. CSCs are also responsible not ...

(mab), named 4h5cr4. by using this mab in combination with antibodies to cd4, cd8α, and 2e3 markers we re-examined the heterogeneity of porcine blood cd4 + t cells and analyzed the expression of several markers associated to t cell differentiation stages on the different subsets. we ...
memory T cells into the TME. These findings were validated in transcriptomic data of aHCC patients treated with atezo/bev versus sorafenib3,4, confirming CD45RA effector-memory CD8 T cells and CXCL10+macrophages as potential predictive biomarkers of response to atezo/bev in aHCC....
