PD-L2 suppresses T cell signaling via coinhibitory microcluster formation and SHP2 phosphatase recruitment

Abstract

Takehara et al performed imaging analysis of microcluster formation between the PD-L1 and PD-L2, which are known to play a role in T cell activation in response to tumour cell signaling. Their analysis showed that the cluster formation inhibited T cell receptor signaling and could serve as a visual index for PD-L1/2-targeted cancer therapies.
