一、前言几乎所有的脊椎动物细胞当其感染某些病毒或与诱异剂接触时都能产生一种或多种糖蛋白——干扰素(IFs)。IFs 能诱导靶细胞对病毒呈拮抗的状态,合成多种蛋白质,特别是一种蛋白激酶,寡聚异腺苷酸合成酶及磷酸二酯酶。此外,IFs 对免疫反应亦有调 I. INTRODUCTION Almost all vertebrate cells produce one or more glycoproteins - Interferons (IFs) when they are infected with certain viruses or come into contact with an attractant. IFs can induce target cells to be antagonistic to the virus and synthesize a variety of proteins, particularly a protein kinase, oligoacid synthase and phosphodiesterase. In addition, IFs also regulate the immune response
