to investigate how t cells recognize allogeneic class i proteins encoded by the major histocompatibility complex ( mhc ) , we examined the human cytotoxic t lymphocytes ( ctl ) elicited in a mixed lymphocyte reaction against a lymphoblastoid b-cell line ( jy ) whose mhc-class i proteins are hla-a2 and -b7 .
