When used with the antiviral drug ribavirin, PEGylated interferon is effective in treatment of hepatitis C; at least 75% of people with hepatitis C genotypes 2 or 3 benefit from interferon treatment, although this is effective in less than 50% of people infected with genotype 1 (the more common form of hepatitis C virus in both the U.S. and ...
Higher interferon stimulated gene expression associated with IFNL4 indicate that this protein does have in vivo antiviral effects, but, at least for HCV infection, other manifestations seem to override those influences. [47] While most interferon stimulated genes have antiviral effects, some may enhance viral replication. [48]
The type-I interferons (IFN) are cytokines which play essential roles in inflammation, immunoregulation, tumor cells recognition, and T-cell responses. In the human genome, a cluster of thirteen functional IFN genes is located at the 9p21.3 cytoband over approximately 400 kb including coding genes for IFNα (IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16 ...
The activation of PKR subsequently triggers interferon signaling, initiating cell death in response to viral dsRNA recognition. While the PKR The roles of PKR activation have been deeply studied with groups finding that it is insensitive to the presence of short dsRNA and siRNA but showing significant affinity for dsRNA and ssRNA with secondary ...
Interferon beta is a protein that in humans is encoded by the IFNB1 gene. [5] The natural and recombinant protein forms have antiviral, antibacterial, and anticancer properties. Interferon beta 1a (tradenames: Avonex and Rebif) and Interferon beta 1b (tradenames: Betaseron/Betaferon) are used as drugs.
ISG15 was originally identified in the late 1970s as a 15-kDa protein produced in response to type I interferon, a potent class of antiviral cytokines. [19] Given the molecular weight, it was originally termed "a 15-kDa protein", but later renamed interferon-stimulated-gene-15 when the cassette of interferon-stimulated genes were recognized.
Type III interferon receptors are expressed more specifically on epithelial cells and some immune cells such as neutrophils, and depending on the species, B cells and dendritic cells as well. [ 13 ] [ 14 ] [ 15 ] Therefore, their antiviral effects are most prominent in barriers, in gastrointestinal, respiratory and reproductive tracts.
Viperin is an interferon-stimulated gene whose expression inhibits many DNA and RNA viruses including CHIKV, HCMV, HCV, DENV, WNV, SINV, influenza, and HIV. [6] Initially identified as an IFN-γ induced antiviral protein in human cytomegalovirus (HCMV) infected macrophages, it was reported that viperin could be induced by HCMV glycoprotein B in fibroblasts, but inhibits HCMV viral infection ...
