第一个TCR结构(Nature,2019)是哈工大黄志伟教授团队揭示的,八聚体TCR–CD3复合物以TCRαβ:CD3γε:CD3δε:CD3ζζ的1:1:1:1化学计量组装,通过疏水和离子相互作用将TCR-αβ的跨膜螺旋插入桶状结构,导致TCR-CD3复合体的跨膜组装。同样,哈工大也是第一次报道TCR结合胆固醇的数据(Mol Cell,2022),揭示胆固醇...
2022年10月,王锋研究员在《Cancer Immunology Research》杂志在线发表题名为“Enhancing the antitumor immunity of T cells by engineering the lipid-regulatory site of the TCR/CD3 complex.”——工程化改造TCR/CD3复合体的脂质调节位...

CAR-T疗法为正常的T细胞配备了肿瘤细胞表面抗原特异性单链抗体,该单链抗体可连接到CD3ζ的胞内区域,在治疗中使用的抗体的亲和力一般高于TCR,因此,CAR-T的激活需要更高浓度的靶抗原[40],而TCR-T通过基因工程改造,对肿瘤细胞的亲和力增强,可被微量靶抗原激活,故TCR...
TCR-CD3复合物(TCR-CD3 complex) 相关知识点: 试题来源: 解析 特异性识别Ag的分子基础,是成熟T细胞的特征性标志。TCRαβ或TCRγδ主要功能是识别结合MHC分子的抗原,胞浆区短;CD3参与TCR/CD3复合体的装配和稳定并通过ITAM传递细胞内信号,引起细胞的活化、增生。

Components and structure of TCR complex The core TCR complex consists of two TCR chains and six cluster of differentiation 3 (CD3) chains. Several other components include coreceptors, kinases, and ligands.14,15 TCR-CD3 chains The human genome expresses four TCR genes known as TCRα, TCRβ,...
we employed RoseTTAFold to model their complex structures.51The crystal structure of 2C-TCR with R4-H-2Kb(PDB code: 1G6R52) served as the initial template for these models. Comparing the dynamic structures of these three TCRs binding with R4- or L4-MHC under force,27we observed that forc...
