Popis: SummaryMouse spleen cells cultured in vitro produced at least two kinds of interferon (IF) in response to inoculation with E. coli endotoxin. The early-appearing IF showed its peak titer about 2 hr after the inoculation of inducer, while the late-appearing IF possessed its maximum titer at 6–8 hr. Their properties were generally similar to those of endotoxin-induced IF in mouse plasma or spleen in vivo. The production of endotoxin-induced IF in mouse plasma or spleen was in parallel with the appearance of lysosomal enzymes, β-glucuronidase and acid phosphatase. In the case of cultured spleen cells in vitro, such parallelism was not observed at all. The production of early-IF in vitro was not affected by treatment with actinomycin D (10μg/ml), but inhibited almost completely by puromycin (50 μg/ml). Both inhibitors caused almost complete inhibition of the production of late-IF.
