  一、个人简介

  许晓东,男,博士,教授,博士生导师,1967年10月出生,黑龙江省甘南县人。1989年在北京农业大学农业微生物专业获学士学位,1995年在北京农业大学微生物学专业获硕士学位,2009年在英国雷丁大学(University of Reading)病毒学专业获博士学位。2009年11月到 生命科学学院工作。主讲本科生“分子生物学”等课程。

  二、研究方向

1. 杆状病毒的分子生物学。包括与病毒晚期基因表达相关的调控因子、病毒与宿主细胞的互作等领域的研究。

2. 朊病毒。近期我们在杆状病毒中发现了病毒中的第一例朊病毒——LEF10。我们推测其他种类的病毒中也存在朊病毒,因此我们拟用实验室已经建立的方法广泛筛选朊病毒。

实验室条件:能完整地实现PCR获得目的基因、克隆到相应的表达载体、原核或真核表达目标蛋白、蛋白质检测、蛋白质间相互作用、重组杆状病毒构建以及通过流式细胞术对细胞进行统计学分析。目前除了一个通用实验室之外,我们还建有一个具备二氧化碳培养箱、倒置显微镜等设备的动物细胞培养室,用于昆虫细胞和哺乳动物细胞培养室。

研究生要求:由于实验室的研究方向涉及广泛的分子生物学知识,因而需要具有坚实的分子生物学理论基础和动手能力、热爱科学研究并具有创新热情的同学加盟。
