英文摘要
Imaging analysis of the negative costimulatory receptor, CTLA-4, revealed the novel mechanism of T cell activation regulation. CTLA-4 formed clusters at the center of the immunological synapse and interfered the formation of the signaling molecule complex, which is composed by the positive costimulatory receptor CD28, kinases, and scaffold proteins. These results suggest that T cell activation is cooperatively regulated by both T cell receptor. CD28 microclusters and the CTLA-4-mediated inhibitory microclusters.
