Résumé
β-arrestins, a kind of important adaptor protein and signal transduction protein found in the purification process ofβ-adrenergic receptor kinase (β-ARK) ,were first identified as pro-teins that have the ability to desensitize G protein-coupled recep-tors ( GPCR) . Fibrosis is defined by the overgrowth, hardening, and scarring of various tissues and is attributed to excess deposi-tion of extracellular matrix ( ECM ) components including colla-gen . A large number of studies have shown thatβ-arrestins play an important role in the process of fibrotic diseases, involved in inflammatory response and excess deposition of ECM. This re-view discusses the research status and development prospects ofβ-arrestins-mediated fibrotic diseases.
Résumé
β-arrestins, important soluble proteins mediating receptor desensitization, have diverse biological functions, such as regulating cell proliferation, cell survival, apoptosis and gene transcription. β-arrestins regulate inflammatory and immune reactions by inhibiting the basal activity of pro-inflammatory transcription factor NF-kB and participating in Toll-like receptors (TLR)/NF-kB signal pathway-mediated NF-kB activation. β-arrestins are involved in the pathogenesis of various inflammatory diseases, such as inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, asthma and so on. The study on β-arrestins will reveal the mechanisms of inflammatory diseases and provide new strategy for clinical treatment. Here we reviewed the recent progress on the role of β-arrestins in regulating the inflammatory diseases.
Résumé
β-arrestins are involved in the insulin signaling pathway, affecting peripheral insulin resistance,also affecting insulin secretion and lipid metabolism. To clarify β-arrestins mediated signaling pathways is an approach to the pathogenesis and effective treatment of diabetes.
