机体干扰素系统的激活是对抗病毒感染的一种防御机制。在正常情况下,这些抗病毒机制并无活性,但当某种病毒冲破机体第一道防御系统并显示它在通常不能发现的部位存在时,这种防御机制可能由隐袭状态进至激活状态。某些细胞因而被激惹,产生一种或多种分子的各种干扰素,后者反过来推动其他细胞进入抗病毒状态,抑制病毒的复制并从而限制病毒感染的扩散。以往曾有学者报告,病毒性肝炎时的干扰素系统与其他 Activation of the body’s interferon system is a defense against viral infections. Under normal circumstances, these antiviral mechanisms are not active, but when a virus breaks through the body’s first defense system and shows that it exists in areas that are usually not found, this defense mechanism may be activated from the insidious state . Some cells are thus provoked to produce various interferons of one or more molecules, which in turn drive other cells into an antiviral state, inhibiting the replication of the virus and thus limiting the spread of the viral infection. There have been previous reports of interferon systems in viral hepatitis and others
