Cooperative binding of T cell receptor and CD4 to peptide-MHC enhances antigen sensitivity

It is known that the T cell co-receptor CD4 greatly enhances the capacity of T cell receptor (TCR) signalling, triggered by the peptide-bound MHC molecule. Here authors show that the mechanistic basis for the enhancement is the co-operative binding of TCR and CD4 to the MHC-peptide complex.
