干扰素（IFN）是治疗慢性丙型肝炎（CHC）唯一有效的抗病毒药物。病毒性肝炎时抗病毒状态的建立不依靠IFN分子本身，而是取决于其诱导的蛋白质，取决于IFN与特异受体的结合，以及结合后细胞内的信息转换。最近作者用肝活检标本进行逆转录聚合酶链反应（RT－PCR）显示，随着与HC Interferon (IFN) is the only effective antiviral for the treatment of chronic hepatitis C (CHC). The establishment of an antiviral state in viral hepatitis does not depend on the IFN molecule itself, but rather on the protein it induces, depending on the binding of IFN to a specific receptor and on the intracellular information transduction after binding. Recently, the authors performed reverse transcription polymerase chain reaction (RT-PCR) with liver biopsy specimens showing that with HC
