Interferon-γ Inhibits Ebola Virus Infection
Ebola virus outbreaks, such as the 2014 Makona epidemic in West Africa, are episodic and deadly. Filovirus antivirals are currently not clinically available. Our findings suggest interferon gamma, an FDA-approved drug, may serve as a novel and effective prophylactic or treatment option. Using mouse-adapted Ebola virus, we found that murine interferon gamma administered 24 hours before or after ...
متن کاملDiagnosis of tuberculosis infection using interferon-γ-based assays.
Interferon-γ-based assays, collectively known as IFN-γ release assays (IGRAs), have emerged as a reliable alternative to the old tuberculin skin test (TST) for the immunodiagnosis of tuberculosis (TB) infection. The 2 commercially available tests, the enzyme-linked immunosorbent assay (ELISA), QuantiFERON-TB Gold Intube (QFT-IT), and the enzyme-linked immunospot assay (ELISPOT), T-SPOT.TB, are ...
متن کاملCardiac glycosides are potent inhibitors of interferon-β gene expression
Here we report that bufalin and other cardiac glycoside inhibitors of the sodium-potassium ATPase (sodium pump) potently inhibit the induction of the interferon-β (IFNβ) gene by virus, double-stranded RNA or double-stranded DNA. Cardiac glycosides increase the intracellular sodium concentration, which appears to inhibit the ATPase activity of the RNA sensor RIG-I, an essential and early compone...
متن کاملSwine influenza virus strains that induce interferon β in SJPL cells but are insensitive to exogenous recombinant swine interferon β
Background: Viral infections induce expression of type I interferons (IFNα/β) which result in an antiviral state within cells or animals. However, some viruses, notably influenza viruses (IV), have evolved mechanisms of evasion and blocking of IFN to survive in nature. Swine influenza virus (SIV) can inhibit IFN and as with other IV does it through its NS1 protein, identified as a virulence fac...
متن کاملExpression Pattern of Interferon-γ in Human Leukemic T Cell Lines Following Treatment with Phytoheamagglutinin, phorbol myristate acetate and Lipopolysaccharide
Background: As a T helper type 1 (Th1) derived cytokine, Interferon gamma (IFN-γ) is an important regulator of inflammatory immune responses. Furthermore, IFN-γ plays an essential role in defense against tumors and intracellular pathogens. This study was designed to assess the pattern of IFN-γ production in human leukemic (Jurkat and Molt-4) T cell lines in vitro. Methods: Ju...
