    摘要:

    在过去的几十年间,随着社会发展和气候变暖等原因,登革热在全球的流行范围不断扩大?发病率急剧上升,已成为一个全球性公共卫生问题?建立理想的登革热动物模型对研究登革病毒感染及发病机制至关重要?鉴于登革病毒的种属特异性及特殊的致病机制,登革病毒感染动物模型的建立面临诸多挑战?登革病毒感染免疫缺陷小鼠,可产生高水平的病毒复制和严重的临床表现,如血管通透性增加及血小板下降等;但部分症状与人类不同,如出现神经症状?登革病毒感染人源化小鼠模型,可研究人体对登革病毒的部分免疫反应,但并不全面和准确?登革病毒可感染非人灵长类动物,但通常不产生明显的临床症状?因此,仍需进一步研究各种登革病毒感染模型,建立更理想的动物模型,支撑登革病毒发病机制研究及抗病毒药物?疫苗的临床前评价?本文汇集了近年来建立登革病毒感染动物模型的研究进展以及动物模型在病毒发病机制?疫苗评估?药物测试等方面的应用情况,为登革病毒感染模型的研究和应用提供参考信息?

    Abstract:

    An increase in the global population and climate warming over the past few decades has increased theglobal epidemic and incidence of Dengue fever, which is now a global public health problem. It is essential to establishideal animal models of Dengue fever to study the infection mechanism and pathogenesis of Dengue virus. In view of thespecies specificity and specific pathogenesis of Dengue virus, research on animal models of Dengue virus infection facesmany challenges. Specifically, immunodeficient mice infected with Dengue virus produce high levels of viral replication andsevere disease manifestations, such as increased vascular permeability and thrombocytopenia; however, some symptomssuch as neurological symptoms differ from those of humans. The humanized mouse model of Dengue virus infection can studythe human immune response to Dengue virus, but it is not comprehensive or accurate. Dengue virus also effectively infectsnon-human primates, although they do not usually develop significant clinical symptoms. Therefore, it is necessary toimprove and establish Dengue virus infection models to support research on the pathogenesis of Dengue virus and thepreclinical evaluation of antiviral drugs and vaccines. This paper brings together the research progress of animal models ofDengue virus infection in recent years, and provides reference information for the research and application of the Dengue virus infection model.
