The T cell receptor (TCR) complex consists of eight transmembrane chains that are expressed on the surface of T cells. The TCRα and TCRβ chains bind antigenic peptide when presented to them in the contact of MHC (major histocompatability) molecules. The other six chains form the CD3 ...
T细胞受体(Tcellreceptor,TCR)是开启T细胞分化与功能的关键开关蛋白质,其识别的配体为短肽-主要组织相容性复合物(peptide-major histocompatibility complex,pMHC)。其中短肽多为数十个氨基酸组成的短链蛋白分子,其来源为肿瘤细胞、病原微生物和自身被降解的蛋白质等。pMHC作为一类抗原大分子,TCR对pMHC的特异性结合与识别...
‹T-Cell Receptor (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 ...
T CELL RECEPTORS The T cell receptor (TCR) is a T cell surface structure that is comprised of a disulfide-linked heterodimer of highly variable α and β chains expressed at the cell membrane as a complex with the invariant CD3 chains. Most T cells that bear this type of receptor are ter...
Gamma delta (γδ) T cells, a unique T cell subgroup, are crucial in various immune responses and immunopathology1,2,3. The γδ T cell receptor (TCR), which is generated by γδ T cells, recognizes a diverse range of antigens independently of the major histocompatibility complex2. The ...

T 细胞受体工程化 T 细胞(T cell receptor-engineered T cells,TCR-T)利用基因工程技术在 T 细胞上表达特异性识别肿瘤抗原的 T 细胞受体(T cell receptor,TCR),使之能特异性地靶向肿瘤细胞,清除肿瘤,被认为有机会突破实体瘤的细...
The adaptive phase of the immune response begins with engagement on CD4+ helper T cells of the T cell antigen receptor (TCR)1 by its ligand, a small foreign peptide bound to a cell surface protein of the class II major histocompatibility complex (peptide-MHC) expressed on an antigen-presenti...
Each T cell expresses a unique TCR that is generated by randomly assorting genes. This ensures that T cells can respond (at the population level) to almost any infection. Latest Research and Reviews Mapping the extracellular molecular architecture of the pAg-signaling complex with α-Butyrophilin ...
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 ...
