最近,美国匹兹堡大学的几位科学家发现了干扰素抗病毒作用的一种新机制,即干扰素可以阻止病毒进入动物细胞内部。他们认为,这可能是干扰素所建立的防范病毒侵袭的第一道防线。(见Proceedings of the U.S.National Academy of Sciences Vol.80, P. 1083)。大量的研究工作已经证明,用干扰素处理的细胞能以几种方式干扰病毒的生活周期,其中特别是干扰素能阻止储存在病毒基 Recently, several scientists at the University of Pittsburgh in the United States have discovered a new mechanism by which antiviral effects of interferon can stop viruses from entering the interior of animal cells. In their opinion, this may be the first line of defense established by interferons against virus attacks. (See Proceedings of the U.S. National Academy of Sciences Vol. 80, p. 1083). Numerous studies have shown that interferon treated cells can interfere with the life cycle of the virus in several ways, and in particular, interferons can prevent the virus
