虽然研究结果表明TRAIL处理对TRAIL- R /SHP-1/Lck复合体有影响,并且与SHP-1磷酸化增强有关,但SHP-1磷酸化对Lck活性的实际作用仍不清楚,需要进一步深入探索以阐明这些微簇成分的空间和动力学关系,以解决TCR复合体、Lck、TRAIL- R和SHP...
因此,TAOK3对SHP-1丰度的调节作为T细胞受体(TCR)信号的调节器,决定了T淋巴细胞的激活阈值。 研究结果表明,TAOK3是一种对TCR信号至关重要的丝氨酸和苏氨酸激酶。它的缺失导致TCR信号减少,并且酪氨酸磷酸酶SHP-1与激酶LCK的相互作用增加,LCK是TCR信号的关键下游介质(图1B)。 图1.A:SHP-1-TAOK3相互作用模型结...

Conclusions: TRAIL-R associates with phosphatase SHP-1 and transduces a unique and distinct immune gatekeeper signal to repress TCR signaling and T cell activation via inactivating Lck. Thus, our results define TRAIL-R as a new class of immune checkpoint receptors for rest...

1e)24. To generate T cells lacking all PKD isoforms, we established T cell-specific PKD2/PKD3 double-deficient mice using Lck-Cre Tg mice (PKD2/3ΔT) (Fig. 2a,b). We confirmed that none of the three PKD isoforms was expressed in PKD2/3ΔT thymocytes using Abs reacting with PKD1, ...
We found that LCK recruited into the synapse of CD28-encoding CAR by co-receptors causes antigen-independent CAR-CD3ζ phosphorylation and increased antigen-dependent T cell activation. In contrast, the synapse formed by 4-1BB-encoding CAR recruits the THEMIS-SHP1 phosphatase complex that ...
