The antiviral response to gamma interferon.
A role for alpha/beta interferon (IFN-alpha/beta) in the IFN-gamma antiviral response has long been suggested. Accordingly, possible roles for autocrine or double-stranded-RNA (dsRNA)-induced IFN-alpha/beta in the IFN-gamma response were investigated. Use was made of wild-type and a variety of mutant human fibrosarcoma cell lines, including mutant U5A cells, which lack a functional IFN-alpha/be...
متن کاملDevelopment of the Antiviral State in Response to Interferon
The development of resistance in response to interferon depends on cellular RNA synthesis and probably also on cellular protein synthesis. The evidence for these requirements is reviewed, as well as the proposal that this evidence indicates the existence of a specific response of the cell to interferon, involving the induced synthesis of an antiviral protein. Direct evidence for such an interpr...
متن کاملRegulation of macrophage growth and antiviral activity by interferon- gamma
Interferons, in addition to their antiviral activity, induce a multiplicity of effects on different cell types. Interferon (IFN)-gamma exerts a unique regulatory effect on cells of the mononuclear phagocyte lineage. To investigate whether the antiviral and antiproliferative effects of IFN-gamma in macrophages can be genetically dissociated, and whether IFN-alpha and IFN-gamma use the same cellu...
متن کاملEvasion of the Interferon-Mediated Antiviral Response by Filoviruses
The members of the filoviruses are recognized as some of the most lethal viruses affecting human and non-human primates. The only two genera of the Filoviridae family, Marburg virus (MARV) and Ebola virus (EBOV), comprise the main etiologic agents of severe hemorrhagic fever outbreaks in central Africa, with case fatality rates ranging from 25 to 90%. Fatal outcomes have been associated with a ...
متن کاملIntrapulmonary response to Histoplasma capsulatum in gamma interferon knockout mice.
We examined the immunobiological responses to Histoplasma capsulatum in lungs of gamma interferon (IFN-gamma) knockout mice (GKO mice). Naive GKO mice succumbed by day 9 to intranasal challenge with 2.5 x 10(6) yeasts, whereas all wild-type (WT) mice survived for 45 days. Compared to lungs of WT mice, the lungs of acutely infected GKO mice exhibited dramatically elevated numbers of CFU in lungs...
