finally , preincubation of effector and target cells with an antibody to a monomorphic determinant of major histocompatibility complex class i antigens reduces target-induced cd8 phosphorylation to a greater extent than antibody to a major histocompatibility complex class ii subregion ( dr ) monomorphic determinant , reinforcing the notion that major histocompatibility complex class i antigens interact with cd8+ cells .
