Essentially pure murine interferon-alpha/beta primes poly rI:rC and Sendai virus-induced interferon production in mice.
Intramuscular (i.m.) injection of mice with 2000 IU/g of essentially pure murine interferon-alpha/beta (MuIFN-alpha/beta) 3 h before the induction of IFN by an intraperitoneal (i.p.) inoculation of 10 haemagglutinating units (HAU) per g Sendai virus or 3 micrograms/g polyriboinosinic and polyribocytidylic acid complex (poly rI:rC) elicited a primed IFN response in both cases. Antiserum to MuIFN-alpha/beta neutralized both the priming and antiviral activities of the IFN preparation used. Comparison of the kinetics of primed and unprimed IFN production by Sendai virus indicated that the early (2-4 h) period of IFN production was affected.
