干扰素是一类能抑制病毒在细胞内增殖的糖蛋白,分子量约为2～4万,是由人和动物细胞在病毒、细菌、原虫、立克次体、植物血凝素以及多聚核苷酸诱导产生的。干扰素具有抗病毒增殖、抗细胞分裂、调节免疫反应等多种生物功能,它能选择性地对细胞的有害因素发生作用,如对受病毒感染的细胞,肿瘤细胞等起作用,而对正常细胞则影响不大。因此,干扰素早已临床用于治疗病毒和肿瘤方面的疾病,国内已用于病毒性肝炎、流行性出血热、乙型脑炎、疱疹病毒感染、儿童呼吸道感染和某些肿瘤的
Interferons are glycoproteins that inhibit the proliferation of viruses in cells and have a molecular weight of about 2 to 40,000. They are produced by human and animal cells in viruses, bacteria, protozoa, rickettsia, lectins, and polynuclear acids. Acid-induced production. Interferons have a variety of biological functions such as antiviral proliferation, anti-cell division, and modulating immune responses. They can selectively exert effects on harmful factors of cells, such as those that are infected by viruses, tumor cells, etc., but normal. Cells have little effect. Therefore, interferon has long been used clinically for the treatment of viral and oncological diseases and has been used domestically for viral hepatitis, epidemic hemorrhagic fever, Japanese encephalitis, herpes virus infection, respiratory infections in children, and certain tumors.
