Two Keys to Open the Door: How CD8alpha-beta Cooperates with TCR to Read MHC-I in Three Relays

2026-09-30

T cell recognition of target cells works like a two-key access system: TCR is the primary key and CD8alpha-beta is the gatekeeper confirmation. This article breaks down, in three relays, how the co-receptor converts weak and transient recognition int
