干扰素是脊椎动物细胞基因组在干扰素诱生剂作用下所控制产生和分泌的一类细胞功能调节蛋白质。人类干扰素己知有α、β、γ三种类型,均具有抗病毒、抗肿瘤和免疫调节等多种生物学活性。其中α、β(Ⅰ型)干扰素最重要的是抗病毒性能,而γ(Ⅱ型或免疫)干扰素在抑制细胞生长抗 Interferon is a type of cell function regulatory protein controlled and produced by the vertebrate cell genome under the action of an interferon inducer. Human interferons are known to have three types of alpha, beta, and gamma, all of which have various biological activities such as antiviral, antitumor, and immune regulation. Among them, alpha, beta (type I) interferon is the most important antiviral property, and gamma (type II or immune) interferon inhibits cell growth resistance.
