T‐cell antigen receptor (TCR) interaction with cognate peptide:MHC complexes trigger clustering of TCR:CD3 complexes and signal transduction. Triggered TCR:CD3 complexes are rapidly internalized and degraded in a process called ligand‐induced TCR downregulation. Classic studies in immortalized T‐cell lines have revealed a major role for the Src family kinase Lck in TCR downregulation. However, to what extent a similar mechanism operates in primary human T cells remains unclear.

单独的信号事件控制原代人类 T 细胞中的 TCR 下调和 T 细胞活化

T 细胞抗原受体 (TCR) 与同源肽的相互作用:MHC 复合物触发 TCR:CD3 复合物的聚类和信号转导。触发的 TCR:CD3 复合物在称为配体诱导的 TCR 下调的过程中迅速内化和降解。永生化 T 细胞系的经典研究揭示了 Src 家族激酶 Lck 在 TCR 下调中的主要作用。然而,在多大程度上类似的机制在原代人类 T 细胞中起作用仍不清楚。
