干扰素(Interferon)1957年在英国被生物学家发现。近十几年才明确它是在病毒感染细胞时所产生的具有抗病毒活性的蛋白复合体。Denys和Finter相继证实,给予动物足够剂量的干扰素,可有效的阻止病毒感染。1966年,Stander等由人体血液离心时分离的棕黄色层的白细胞中生产出可供临床使用的干扰素。这种人体白细胞产生的干扰素,是以后很多年临床使用的干扰素唯一来源。干扰素是一种细胞激活素(Cytokines),有很高的生物学活性,lng/ml浓度就能产生所需要的抗病毒效果。干扰素另一特点是它生物活性的多样性;例如,
Interferon was discovered by biologists in Britain in 1957. Nearly a dozen years to make it clear that it is an antiviral protein complex produced by viruses that infect cells. Denys and Finter have confirmed that giving animals sufficient doses of interferon effectively prevents viral infections. In 1966, Stander et al. Produced interferon for clinical use in the buffy coat of leukocytes isolated from human blood by centrifugation. This human leukocyte-producing interferon is the only source of interferon that has been used clinically for many years. Interferon is a kind of cytokines (Cytokines), has a high biological activity, lng / ml concentration can produce the desired antiviral effect. Another characteristic of interferon is its biological diversity; for example,
