What is the function of the CD8 receptor?

1 Answer

  1. Answer:

    CD8 acts as a co-receptor during T-cell antigen engagement. The dominant molecular basis for this functional role in antigen recognition centers on the association of the CD8 α-chain with p56Lck, via two vicinal cysteines, which interact through a zinc chelate complex to produce a co-activation signal.
