干扰素(简称IFN)是在一定诱生剂的作用下,由细胞分泌的一类蛋白质,具有广谱的抗病毒、抗肿瘤以及免疫调节活性。目前临床上使用的干扰素,主要限于从人白细胞制备。由于干扰素的种属特异性的限制,细胞来源有限和价格昂贵,因而限制了它的大量生产和应用。近年来,由于对干扰素种属 Interferon (IFN) is a type of protein secreted by cells under the action of a certain inducer, and has a broad spectrum of antiviral, antitumor and immunomodulatory activities. Currently used in clinical interferon, mainly limited to the preparation of human leukocytes. Because of the species-specific limitations of interferon, the limited and costly availability of cells limits its mass production and use. In recent years, due to interferon species
