英文摘要
T cell activation is induced by TCR-microcluster(MC). We clarified the molecules accumulated within MCs, and the relationship with costimulation signals and lipid raft. Lipid raft does not function as the platform and protein interaction within MCs induce activation. CD28-mediated costimulation recruits PKCθ-Carma1 to cSMAC, whereas the inhibitory costimulation receptor CTLA-4 inhibits by accumulating in cSMAC and kicking off CD28-PKCθfrom the cSMAC. TCR-MCs associate with the dynein complex and translocate along microtubules to form cSMAC.
