Abstract

Abstract: Human cytotoxic T lymphocytes specific for A/JAP/57 (H2N2) influenza virus were cloned from in vitro stimulations of peripheral blood lymphocytes. Analysis of the viral specificity in cytotoxic function revealed one clone that killed all type A influenza-infected targets, another clone that was specific for the hemagglutinin subtype of the immunizing influenza virus, and the third clone that demonstrated cytotoxicity restricted to the hemagglutinin of A/JAP/57 and A/JAP/62 (H2N2) and not other type A influenza strains with the H2N2 subtypes. The phenotype of these three clones was Leu 2−, Leu 3+, Leu 4+; MHC restriction of their cytotoxic function was mapped to HLA-DR by a panel of target cells as well as by inhibition of cytotoxicity with monoclonal antibodies. Proliferation of these clones, examined in a tritiated thymidine incorporation assay, was found to be driven by antigen in the absence of exogenous lymphokines. For all three clones antigen-dependent production and secretion of lymphokines with IL-2 activity was demonstrated. The antigen specificity of proliferation and factor production was shown to be identical to the pattern that each clone revealed in its cytotoxic function.
