Based on the type of receptor through which they signal, human interferons have been classified into three major types. Interferon type I: All type I IFNs bind to a specific cell surface receptor complex known as the IFN-α/β receptor (IFNAR) that consists of IFNAR1 and IFNAR2 chains. The type I … Meer weergeven Interferons are a group of signaling proteins made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby Meer weergeven Production of interferons occurs mainly in response to microbes, such as viruses and bacteria, and their products. Binding of molecules uniquely found in microbes—viral glycoproteins, viral RNA, bacterial endotoxin (lipopolysaccharide), bacterial Meer weergeven Many viruses have evolved mechanisms to resist interferon activity. They circumvent the IFN response by blocking downstream … Meer weergeven Diseases Interferon beta-1a and interferon beta-1b are used to treat and control multiple sclerosis, … Meer weergeven All interferons share several common effects: they are antiviral agents and they modulate functions of the immune system. Administration of Type I IFN has been shown experimentally to inhibit tumor growth in animals, but the beneficial action in human … Meer weergeven By interacting with their specific receptors, IFNs activate signal transducer and activator of transcription (STAT) complexes; STATs are a family of transcription factors that regulate the expression of certain immune system genes. … Meer weergeven Coronaviruses evade innate immunity during the first ten days of viral infection.
