IF 的发现已有22年之久。但关于 IF 的很多方面如产生条件、作用机制、生物活性和实际应用的前景等问题,都尚未充分明嘹。原来以为 IF 只有抗病毒作用,现在已知 IF 的作用远为复杂。它不但有抗病毒的作用,还有调节细胞生长和调节免疫反应的作用。更有意义的是还有抗肿瘤的作用。这后一种作用肯定是与前几种作用相互关联的。这就使 IF 的研究工作,无论是在基础理论或实际应用方面,都正在发生一个新的高潮。
The discovery of IF has been for 22 years. However, many aspects of IF, such as conditions for production, mechanism of action, biological activity, and prospects for practical application, have not yet been fully clarified. It was originally thought that IF has only antiviral effects, and it is now known that the role of IF is far more complicated. It not only has antiviral effects but also regulates cell growth and regulates immune responses. More significant is the anti-tumor effect. This latter role is certainly linked to the previous ones. This has led to a new culmination of IF research, both in basic theory and practical applications.
