A Four-Leg Relay: How CD3εδ Translates Antigen Recognition into T Cell Activation

2026-09-21

T cell activation is a relay race: TCR-alpha/beta binds the pMHC, CD3εδ and CD3εγ transmit the conformational change across the membrane, CD3ζζ converts it into ITAM phosphorylation, and ZAP-70 takes the final leg. This article walks through each bat
