摘要 目的:探讨解决RNA干扰(RNAi)抗HBV作用时间短暂的问题。方法:构建腺病毒/重组腺相关病毒(Ad/rAAV)杂合体病毒,恢复rAAV的定点整合,并借助定点整合的rAAV持续表达shRNA(short hepair RNA),实现RNAi抗HBV的持久性。结果:经酶切和测序鉴定,各目的基因片段均成功克隆入穿梭质粒中pAd/rAAV酶切鉴定表明同源重组成功,病毒包装与滴度测定结果表明,Ad/rAAV杂合体病毒包装成功。结论:利用Ad、AAV和HBV各种元件的特点,彼此互补,克服其不足,构建Ad/rAAV杂合体病毒,作为抗HBV的shRNA表达框的载体,为解决RNAi抗HBV作用时间短暂的问题作了一些技术上的探索。
