产品说明
β型干扰素(Interferon-β,IFN-β)是主要由成纤维细胞产生的细胞因子,属于单一基因编码产生的蛋白质,可通过干扰病毒RNA或DNA复制而抑制病毒生长,并可显著增强NK细胞杀伤活性,通过促进MHCⅠ类分子表达而增强CTL对病毒感染细胞的识别和杀伤作用. The mammalian type I Inteferons (IFN1) are produced in response to viral infection and other inducers. They are divided into alpha and beta subtypes leukocytes and fibroblasts reactivity. The human IFN alphas are encoded by a family of at least 15 different genes, while IFN beta is the unique member of its subtype. There is approximately 50% amino acid homology between the alpha and beta subtypes. Both IFN subtypes are pleiotropic cytokines and have a similar range of biological activities. Differences between alpha subtypes, and between IFN alpha and betas, are in potency and cell type specific activities. In particular, IFN beta elicits a markedly higher antiproliferation response in some cell types such as, embryonal carcinoma, melanoma and melanocytes than do IFN alphas. Higher potency of IFN beta in treatment of multiple sclerosis and certain cancers has been observed. Type I IFNs signal through binding to a common cell surface receptor. Two chains of the receptor, IFNAR1 and IFNAR2, have been identified. Both chains are necessary for function and in the absence of either there is neither high affinity binding nor biological activity. The intracellular portions of the receptor subunits are bound by tyrosine kinases, Jak1 and Tyk2, members of the Janus kinase family. Upon ligand binding these kinases are activated and phosphorylate members of the STAT family of transcription factors, as well as IFNAR1 and 2. Also known as: Fibroblast interferon; IFB; IFF; IFN beta; IFNB 1; IFNB ; IFNB1; Interferon beta 1 fibroblast ; Interferon beta precursor; MGC96956
