The regulation of inflammation by interferons and their STATs
نویسندگان
چکیده
Interferons (IFN) are subdivided into type I IFN (IFN-I, here synonymous with IFN-α/β), type II (IFN-γ) and type III IFN (IFN-III/IFN-λ) that reprogram nuclear gene expression through STATs 1 and 2 by forming STAT1 dimers (mainly IFN-γ) or the ISGF3 complex, a STAT1-STAT2-IRF9 heterotrimer (IFN-I and IFN-III). Dominant IFN activities in the immune system are to protect cells from viral replication and to activate macrophages for enhanced effector function. However, the impact of IFN and their STATs on the immune system stretches far beyond these activities and includes the control of inflammation. The goal of this review is to give an overview of the different facets of the inflammatory process that show regulatory input by IFN/STAT.

Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...

Treating Central Nervous System (CNS) neuro-inflammational disorders is of great importance. A key aspect of this treatment includes regulation of Cell-Mediated and humoral immune systems. Previous treatment mostly consisted of systemic immunosuppressive drugs. In addition to having adverse side effects, these drugs were also inefficient, such as methotrexate- Cyclophosphamide-Azathioprine. Rec...

Immune and inflammatory systems are controlled by multiple cytokines, including interleukins (ILs) and interferons. These cytokines exert their biological functions through Janus tyrosine kinases and signal transducer and activator of transcription (STAT) transcription factors. We recently identified two intrinsic Janus kinase (JAK) inhibitors, JAK binding protein (JAB; also referred to as supp...

Interferons (IFNs) are pleotropic cytokines with strong anti-viral and immunomodulatory properties. Their function is dependent to signaling pathway upon binding to IFN receptor. Both pro- and anti-inflammatory effects are seen in interferons-related immune responses. While, interferons are in direct correlation with autoantibodies production during autoimmunity, they have protective effects. T...

Coronaviruses belong to the Coronaviridae family and three SARS-CoV, MERS-CoV and SARS-CoV-2 pathogens are found in this family, all of which cause respiratory disorders in human beings. SARS-CoV-2 is a RNA virus of approximately 80-160 nm in size and genomic size of approximately 27-35 kb which causes COVID-19. Symptoms of COVID-19 include fever, dry cough, fatigue and muscle weakness, shortne...
