Nonspecific T cell-replacing factors prepared as supernatants from mixed lymphocyte cultures or concanavalin A-stimulated spleen cells are active in vivo iv injected into nude mice at least 3 days before antigen. The supernatants appear to act by enhancing the week IgM responses that occur in untreated nudes. Secondary responses and IgG antibody were not found.
