title: [Interferon production in human T lymphoblastoid cells].
abstract: Human T lymphoblastoid cell (RPMI 8402 cell) produced interferon (IFN) through the induction by Sendai virus. The priming effect on the interferon production in the RPMI 8402 cell could be found by the pretreatment of human leukocyte IFN (Hu IFN-alpha), but not by that of the IFN produced in the RPMI 8402 cell (T-IFN). The superinduction by the irradiation of ultraviolet rays or the treatment of antimetabolites (actinomycin D and cycloheximide) or 5-bromodeoxyuridine was not found. The T-IFN was completely neutralized by the anti-Hu IFN-beta serum, but not by the anti-Hu IFN-alpha serum at all. In conclusion, it was confirmed that the IFN produced in the RPMI 8402 cell through the induction by Sendai virus was antigenically identical to Hu IFN-beta.
