ISGs are genes whose expression can be stimulated by interferon, but may also be stimulated by other pathways. [1] Interferons are a type of protein called a cytokine, which is produced in response to infection. [9] When released, they signal to infected cells and other nearby cells that a pathogen is present. [9]
Interferon-stimulated gene 15 (ISG15) is a 17 kDa secreted protein that in humans is encoded by the ISG15 gene. [ 5 ] [ 6 ] ISG15 is induced by type I interferon (IFN) and serves many functions, acting both as an extracellular cytokine and an intracellular protein modifier.
Interferome is an online bioinformatics database of interferon-regulated genes (IRGs). [1] These Interferon Regulated Genes are also known as Interferon Stimulated Genes (ISGs). The database contains information on type I (IFN alpha, beta), type II (IFN gamma) and type III (IFN lambda) regulated genes and is regularly updated.
Upon activation, STING stimulates TBK1 activity to phosphorylate IRF3 or STAT6. Phosphorylated IRF3s and STAT6s dimerize, and then enter nucleus to stimulate expression of genes involved in host immune response, such as IFNB, CCL2, CCL20, etc. [8] [23] Several reports suggested that STING is associated with the activation of selective autophagy ...
The gene encoding IFNα2, the IFNA2 gene, is clustered with all other type I IFN genes on chromosome 9 [8] and as all type I IFN genes, it is devoid of intron. [9] The open reading frame (coding sequence) of IFNA2 codes for a pre-protein of 188 amino acids with a 23 amino acid signal peptide allowing secretion of the mature protein.
Virtually every cell in the body requires iron in order to function well. Iron is involved in key bodily processes, including the transportation of oxygen in the blood.
“The brain changes, and it doesn’t recover when you just stop the drug because the brain has been actually changed,” Kreek explained. “The brain may get OK with time in some persons. But it’s hard to find a person who has completely normal brain function after a long cycle of opiate addiction, not without specific medication treatment.”
The type I IFNs bind type I IFN receptors on the surface of the cell that produced them, and also other cell types that express the receptor, to activate JAK-STAT (Janus kinase/signal transducers and activators of transcription) signaling. This leads to the induction of hundreds of interferon stimulated genes (ISGs) that amplify the IFN ...
