the role of the interaction of cd2 molecules with lymphocyte function-associated antigen 3 ( lfa-3 ) in facilitating nominal antigen recognition by t lymphocytes was studied by utilizing an hla-dr4-restricted cd4+ cytotoxic human t-cell clone specific for human immunodeficiency virus envelope glycoprotein gp120 as a responder and murine fibroblasts transfected with human class ii major histocompatibility complex ( mhc ) and/or human lfa-3 molecules as antigen-presenting cells ( apc ) .
