Abstract

Hepatitis B virus (HBV) replication is inhibited in a noncytopathic manner by alpha/beta interferon (IFN-alpha/beta) and IFN-gamma. We demonstrate here that inhibitors of cellular proteasome activity can block this antiviral effect. These results suggest that a critical component of the IFN-induced antiviral response may be the proteasome-dependent degradation of viral or cellular proteins that are required for HBV replication.

摘要

乙型肝炎病毒(HBV)的复制受到α/β干扰素(IFN-α/β)和γ干扰素的非细胞病变方式抑制。我们在此证明,细胞蛋白酶体活性抑制剂可阻断这种抗病毒作用。这些结果表明,IFN诱导的抗病毒反应的一个关键组成部分可能是蛋白酶体依赖性降解HBV复制所需的病毒或细胞蛋白。
