Cloning, expression and antiviral activity of mink alpha-interferons
BACKGROUND As a key link between innate and adaptive immune responses, the interferon (IFN) system is the first line of defense against viral infection. IFN, and in particular, IFN-α, has been used clinically as an effective therapeutic agent for viral infections. However, different subtypes of IFN-α demonstrate distinct antiviral activity. Therefore, it is important to identify IFN-α subtypes ...
متن کاملAntiviral defense: interferons and beyond
Mice lacking the adaptor protein that initiates an antiviral response downstream of the RNA helicases retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) have recently been described. These studies highlight the essential and nonredundant role of nucleic acid recognition in the induction of type I interferon production and raise important questions regar...
متن کاملAvian Interferons and Their Antiviral Effectors
Interferon (IFN) responses, mediated by a myriad of IFN-stimulated genes (ISGs), are the most profound innate immune responses against viruses. Cumulatively, these IFN effectors establish a multilayered antiviral state to safeguard the host against invading viral pathogens. Considerable genetic and functional characterizations of mammalian IFNs and their effectors have been made, and our unders...
متن کاملAntiviral activity of bacteria-derived human alpha interferons against encephalomyocarditis virus infection of mice.
Bacteria-derived human leukocyte interferon (IFN) subtypes, IFN-alpha A, -alpha B, and -alpha D, and two hybrid IFNs, IFN-alpha AD and -alpha DA, were examined for both in vitro and in vivo antiviral activity. Two of these materials in highly purified form (IFN-alpha D and -alpha D) protect mice against lethal doses of encephalomyocarditis virus infection. A single dose of 1 microgram of protei...
متن کاملComparison of Antiviral Activity of Recombinant and Natural Interferons Against Crimean-Congo Hemorrhagic Fever Virus
As a first line of defence against a virus infection, mammalian cells elicit an innate immune response, characterized by secretion of type I interferons (IFN) and up-regulation of interferon stimulated genes (ISGs). We have previously included Crimean Congo Hemorrhagic Fever Virus (CCHFV) in the list of type I IFN-sensitive viruses. In this in vitro study, we have compared the antiviral activit...
