干扰素(Interferon,IFN)受体蛋白是宿主细胞分泌的一类细胞因子,可调节免疫应答。作为被发现的第一类细胞因子,它被命名为“干扰素”,因为这种蛋白质能够干扰病毒的复制。当存在病原体时,通常由宿主细胞释放干扰素,周围未感染的细胞感知后激活适当的细胞防御机制,以便消除病原体。IFN细胞因子根据其结合的不同干扰素受体分为三种类型(I型、II型和III型);每种IFN细胞因子诱导一种特定的免疫反应。此外,IFN细胞因子介导信号会促进主要组织相容性I类和II类分子(MHC I,MHC II)的上调,并活化许多下游信号级联,从而生成抗病毒防御机制。
干扰素β(Interferon beta,IFN-β,IFNb)是细胞中第一波细胞因子反应的一部分。病原体感染可导致干扰素调节因子3(IRF3)的激活,该因子以反式激活IFN-β基因转录。与其他干扰素相比,IFN-β在生物学上是独特的,研究表明,与IFN-α相比,IFN-β具有重叠和不同的基因表达模式。似乎IFN-β以比其他I型IFN更高的亲和力与I型IFN-受体结合,并且它还可以以不同的方式调节受体内化。此外,IFN-β长期以来一直被认为可以抑制病毒复制,作为身体先天抗病毒反应的一部分,并被用作治疗多发性硬化症(MS)和一些肿瘤的药物。
