T-cell receptors (TCRs) recognize small protein fragments (peptides) that are displayed on the surface of antigen-presenting cells. 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...

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...
2023年7月24日,英国卡迪夫大学医学院免疫学教授Andrew Sewell课题组于著名期刊《Cell》上发表了一篇名为“Targeting of multiple tumor-associated antigens by individual T cell receptors during successful cancer immunotherapy”的研究型论文。他们发现在癌症免疫疗法成功后,多表位靶向的单个 T 细胞可同时以多种方式...
TCR activation is regulated by various co-stimulatory receptors. CD28 provides an essential co-stimulatory signal during T-cell activation, which augments the production of IL-2 (Interleukin-2), increases T-cell proliferation and prevents the induction of anergy and ...

Interaction of the T cell receptor (TCR) with an MHC-antigenic peptide complex results in changes at the molecular and cellular levels in T cells. The outside environmental cues are translated into various signal transduction pathways within the cell, wh
CAR-T抑制HIV复制效果优于TCR-T CAR-T的全称是Chimeric Antigen Receptor T-Cell，即嵌合抗原受体T细胞。CAR-T疗法近年来在肿瘤免疫领域大放异彩。简单来说，CAR-T疗法就是通过生物技术改造病人的免疫T细胞，令其识别肿瘤细胞表面的抗原，然后把这些细胞输回病人体内，它们识别肿瘤细胞的能力更强，就能达到更好的杀伤...
