慢性乙型肝炎病毒(HBV)感染是急性和慢性肝病的主要原因。我们最近描述了HBV和土拨鼠肝炎病毒(WHV)显性阴性(DN)核心突变体,它们能够抑制野生型病毒复制95%。这些突变体可能代表了一类有效的抗病毒药物,作为“细胞内免疫原”。为了促进它们在动物模型系统中的潜在应用,我们现在研究了鸭HBV (DHBV),并将DN突变体构建在重组逆转录病毒和腺病毒表达载体中。瞬时表达与WHV和HBV DN结构等效的DHBV分子可抑制野生型DHBV复制98%。利用含有HBV和DHBV DN互补dna (cdna)的重组逆转录病毒和腺病毒载体,短暂而稳定地转导表达野生型病毒的肝癌来源细胞系。这些研究表明,当传递到细胞内时,DN核心突变体是HBV和DHBV复制的强大抑制剂,并且似乎是肝脏持续病毒感染的基因治疗中有希望的抗病毒药物。
Chronic hepatitis B virus (HBV) infection is a major cause of acute and chronic liver diseases. We have recently described HBV and woodchuck hepatitis virus (WHV) dominant negative (DN) core mutants that were capable of inhibiting wild‐type viral replication by 95%. These mutants may represent a potent class of antiviral agents that act as “intracellular immunogens.” To facilitate their potential use in animal model systems, we now have studied the duck HBV (DHBV) and placed the DN mutant constructs in recombinant retroviral and adenoviral expression vectors. Transient expression of the DHBV molecular equivalent of the WHV and HBV DN constructs inhibited wild‐type DHBV replication by 98%. Recombinant retroviral and adenoviral vectors containing the HBV and DHBV DN complementary DNAs (cDNAs) were used to transiently and stably transduce hepatoma‐derived cell lines constitutively expressing replicating wild‐type virus. These investigations show that the DN core mutants were powerful inhibitors of HBV and DHBV replication when delivered intracellularly and appear as promising antiviral agents for gene therapy of persistent viral infection of the liver.
