title: Immune interferon produced in vitro as a quantitative indicator of cell-mediated immunity.
abstract: The present study was constructed to provide some information on the possibility of utilizing immune interferon as a quantitative indicator of cell-mediated immunity and to clarify some of the nature of immune interferon-producing cells (IIPC). When spleen cells derived from L cell-sensitized mice were co-cultivated with L cells, interferon appeared in the culture fluid. It was shown by additional experiments that the cells responsible for immune interferon production in this system were T-lymphocytes assisted by macrophages. The pattern of kinetics of immune interferon production in vitro was similar to that of migration inhibitory factor or T cell-mediated cytotoxicity.
