干扰素是机体免疫系统的重要组成部分,具有抗病毒、抗肿瘤作用,并可调节机体免疫功能。近年来,因其广泛的生物学活性,干扰素已受到越来越多研究人员的重视,以鸭为代表的水禽干扰素研究也初见成效。本文从鸭干扰素的表达、抗病毒作用、免疫调节作用和在临床中的应用等方面,综述了国内外关于鸭干扰素的研究概况。 Interferon is an important part of the body’s immune system, with antiviral and anti-tumor effects, and can regulate the body’s immune function. In recent years, due to its extensive biological activity, interferon has been paid more and more attention by researchers. The research on waterfowl interferon represented by duck has also achieved initial success. This review summarizes the research progress of duck interferon both at home and abroad from the aspects of duck interferon expression, antiviral effect, immunomodulatory effect and its clinical application.
