Interferons can disrupt signaling by other stimuli. For example, interferon alpha induces RIG-G, which disrupts the CSN5-containing COP9 signalosome (CSN), a highly conserved multiprotein complex implicated in protein deneddylation, deubiquitination, and phosphorylation. [24]
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 ...
For a viral infection, examples include: prohibiting entry of the virus into uninfected cells, stopping viral replication, and preventing the virus from leaving an infected cell. [ 1 ] Another ISG function is regulating interferon sensitivity of a cell. [ 1 ]
Interferon gamma (IFNG or IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. [5] The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes. [6]
Interferon beta-1a (also interferon beta 1-alpha) is a cytokine in the interferon family used to treat multiple sclerosis (MS). [5] It is produced by mammalian cells, while interferon beta-1b is produced in modified E. coli. [6] Some research indicates that interferon injections may result in an 18–38% reduction in the rate of MS relapses. [7]
Interferon alfa or HuIFN-alpha-Le, trade name Multiferon, is a pharmaceutical drug composed of natural interferon alpha (IFN-α), obtained from the leukocyte fraction of human blood following induction with Sendai virus. Interferon alfa contains several naturally occurring IFN-α subtypes and is purified by affinity chromatography.
Stimulator of interferon genes (STING), also known as transmembrane protein 173 (TMEM173) and MPYS/MITA/ERIS is a protein that in humans is encoded by the STING1 gene. [ 5 ] STING plays an important role in innate immunity .
Interferon-related developmental regulator 1 is a protein that in humans is encoded by the IFRD1 gene. [ 5 ] [ 6 ] The gene is expressed mostly in neutrophils , skeletal and cardiac muscle, the brain, and the pancreas.
