    摘要:

    日本脑炎病毒(Japanese encephalitis virus,JEV)感染人体后首先会逃避先天免疫的Ⅰ型干扰素(I-interferon,I-IFN)的抑制作用,进而感染其他细胞和组织,引起痉挛、神经退行性病变和神经性炎症等系列严重症状甚至死亡。JEV主要通过抑制IFN-α/β产生和干扰素的Janus 激酶( Janus kinase,Jak)-信号转导和转录激活子( signal transducer andactivator of transcription,STAT)信号通路来逃逸先天免疫,基于JEV的免疫逃逸机制构建了多种小鼠感染模型,用于JEV感染的致病机制和治疗方案研究。本文在阐述JEV的IFN免疫逃逸机制的基础上,系统介绍了相应的小鼠感染模型,分析该类小鼠模型的特点、人类症状的模拟程度等,基于此可能发现新的研究靶点,进而开发新的JEV感染小鼠模型,为JEV研究提供理想的动物模型。

    Abstract:

    Japanese encephalitis virus (JEV) usually evades the inhibitory effect of innate immunity type I interferon (I-IFN) when infects human cells and tissues, then causes a series of serious symptoms such as spasticity, neurodegenerative lesions, neuroinflammation and even death. Generally, JEV escapes innate immunity by inhibiting IFN-α/βproduction and interferon’ Janus kinase (Jak)-signal transducer and activator of transcription (STAT) signaling pathway. Because of this special immune escape mechanism, various mouse infection models have been constructed for the study of the pathogenesis and therapeutic regimen of JEV infection. In this review, based on the exposition the IFN immune escape mechanism of JEV, we systematically introduced the JEV infected mouse models, analyzed the characteristics of these models and the degree of simulation of human symptoms, etc. To sum up, we hope to develop various new JEV infected mouse models based on the new research targets may be found and provide novel ideal animal models for JEV research.
