For example, in January 2001, the Food and Drug Administration (FDA) approved the use of PEGylated interferon-alpha in the USA; in this formulation, PEGylated interferon-alpha-2b (Pegintron), polyethylene glycol is linked to the interferon molecule to make the interferon last longer in the body. Approval for PEGylated interferon-alpha-2a ...
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 ...
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.
[6] [12] Because the receptors for type I and type II interferons are expressed on almost all nucleated cells, their function is rather systemic. 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.
An interferon-stimulated gene (ISG) is a gene that can be expressed in response to stimulation by interferon. [1] [2] Interferons bind to receptors on the surface of a cell, initiating protein signaling pathways within the cell. This interaction leads to the expression of a subset of genes involved in the innate immune system response. [1]
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]
Adenovirus, herpes simplex virus, HSV-1 and HSV-2, as well as the negative-stranded RNA virus, vesicular stomatitis virus (VSV), have been shown to be able to activate a STING-dependent innate immune response. [14] STING deficiency in mice led to lethal susceptibility to HSV-1 infection due to the lack of a successful type I interferon response ...
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.
