上期文章《 细胞免疫研究的核心通路——T cell receptor signaling pathway(上) 》中,介绍了TCR信号通路的结构、相关膜表面蛋白及通路主要过程,今天继续分享TCR信号通路的关键调节结点、T细胞发育过程中的TCR信号通路调节、CD28超家族的共刺激/抑制作用。 一、TCR信号通路的关键调节结点 1.1 LCK结点的调节 酪氨酸激酶LCK...
T细胞是适应性免疫反应的主要细胞类型,在病原体清除和肿瘤监测中发挥核心作用。T细胞受体(T cell receptor,TCR)可以让T细胞特异性识别靶细胞膜表面的抗原(由MHC复合物呈递)并激发细胞免疫反应。关于T细胞以及TCR如何体内如何发育成熟,在基迪奥系列丛书《单细胞测序完全解析》中的第五章有专门介绍,这里就不重复赘述。本期...
T Cell Receptor Signaling Pathway Background T cell receptors (TCR) play a key role in functioning of T cells and formation of the immunological synapse. It provides connection between T cell and the antigen-presenting cell (APC). TCRs activation promotes a number of signaling cascades that ult...
TCR-T(T-cell receptor engineered T cells)疗法是一种新型细胞免疫治疗方法,通过对患者的 T 细胞进行改造使其识别并攻击肿瘤细胞。尽管与 CAR-T 相比,TCR-T 的临床转化和上市历程貌似慢了很多,但是由于 TCR-T 不仅能靶向细胞表面抗原,还能靶向细胞内抗原,因此有望改变许多肿瘤(特别是实体瘤)的治疗范式。 Afami...
‹T细胞受体(TCR) TCR Cell Signaling Pathway T-cells are a subset of lymphocytes that play a large role in the immune response. The TCR (T-cell receptor) is a complex of integral membrane proteins that participate in the activation of T-cells in response ...

Deficiency of metabolic regulator PKM2 activates the pentose phosphate pathway and generates TCF1+progenitor CD8+T cells to improve immunotherapy TCF1+progenitor-exhausted CD8+T cell populations mediate durable antitumor immunity. Upon antigenic stimulation, effector T cells upregulate aerobic glycolysis to ...
CAR-T therapy targeting brain tumors: CAR-T cells are modified white blood cells expressing a chimeric antigen receptor (CAR) against a specific tumor antigen that holds the potential of identification and elimination of cancer cells. The extraordinary therapeutic effect experienced with CAR-T cell ...
