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...
Other Signaling Pathways 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 s...
‹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 ...

The T Cell Receptor plays a key role in the immune system. The specificity of the receptor is governed by the binding site formed from the mature alpha and beta chains (shown here) or gamma and delta chains in gamma/delta T Cells. It is the ability of this receptor to bind a complex...
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, which mediate the activation of various genes ...
