title: Hyporeactivity of infection: potential limitation to therapeutic use of interferon-inducing agents.
abstract: Interferon inducers are generally most effective as antiviral agents when used prophylactically. One possible explanation for this is that animals develop a state of hyporeactivity during the course of a virus infection. Such a progressive loss of capacity to produce interferon was observed with a representative group of interferon-inducing agents (polyinosinic-cytidylic acid, Tilorone hydrochloride, New-castle disease virus, or a strain of encephalomyocarditis virus) during the course of a model picornavirus infection in mice.
