美国的科学家揭示了以前未被认识的干扰素抗病毒作用的一个方面,这一发现将被加入干扰素己有很广范围的抗病毒感染的机制中。匹兹堡大学的Patricia Whitaker-Dowling等已证明,干扰素可防止病毒进入动物细胞内,并认为这可能是干扰素系统在病毒攻击时建立的第一道防线。(《Proc US Nat Acad American scientists have uncovered an aspect of the previously unknown role of interferon antivirals that would be added to the mechanism by which interferons already have a wide range of antiviral infections.

Of the University of Pittsburgh have demonstrated that interferons prevent the virus from entering animal cells and believe this may be the first line of defense that the interferon system establishes when the virus attacks.
