乙肝病毒体内外感染模型研究进展

乙肝病毒是威胁人类健康的重要病原体之一。目前,利用针对乙肝病毒和宿主分别建立的细胞模型和动物模型,广泛应用于乙肝病毒的基础研究、新药研发和新疗法的探索。但是,这些模型仍然存在某些方面的缺陷,如感染率低、感染期短,与人存在较大的种属差异等,最重要的是,这些模型无法完全模拟乙肝病毒自然感染人的过程及产生病理变化。本文对近十五年来主要乙肝病毒体内外感染模型及其最新的研究进展进行简要综述,为今后建立新型乙肝病毒感染模型提供参考。

Recent progress for HBV infection model in vitro and in vivo

Hepatitis B virus (HBV) is an important pathogen threatening to human health. Up to date, various of cell infection models and animal models for HBV and the host are widely used in the exploring research of infection mechanism, new drug development and effective therapeutic method for HBV. However, these models have some defects, such as low infection rate, rather short infective stage, and comparatively large species differences with human, and so on. Among them, the biggest problem is that these models cannot completely simulate HBV infection process and pathological changes naturally occurred in human. Herein, the major HBV infection models developed in the past fifteen years, as well as the latest research progress, are presented as a brief review, to provide a reference for constructing novel HBV infection models in the future.
