研究领域:
主要研究方向是昆虫生物学与昆虫病毒学。
目前主要关注家蚕抗BmNPV的分子机制。家蚕具有重要经济价值,也是鳞翅目昆虫研究的模式生物。家蚕在饲养中经常收到多种病原体的侵染,特别是杆状病毒BmNPV的感染,常常会造成很大的经济损失。我们方向的陈克平研究员在多年研究中发现了高抗BmNPV的家蚕品系,进行了大规模的基因组学、转录组学及蛋白质组学研究,发现了可能参与家蚕抗病毒的多种基因及蛋白。目前我们正在进一步研究这些靶基因及蛋白的分子功能,以寻找能够决定家蚕抗BmNPV的关键基因及蛋白,为优化家蚕的分子育种提供新的靶标。
我们发现一类Suppressors of Cytokine Signaling (SOCSs)蛋白质家族与家蚕抗BmNPV可能存在关系。SOCS能够通过抑制经典的JAK-STAT 和IFN干扰素途径及NFkB途径来调控细胞生理和病理的各种重要分子途径。研究发现许多种类的病毒都能够诱导SOCS来逃避宿主的抗病毒免疫反应,而宿主也与病毒竞争控制SOCS来限制病毒的感染复制。目前的研究主要是在脊椎动物特别是哺乳动物中开展的,在无脊椎动物特别是昆虫中研究还是非常少。我们关注家蚕的SOCS。家蚕SOCS在BmNPV感染复制中的作用是什么?是否也在家蚕抗BmNPV免疫反应中发挥作用?我们正在对这些问题进行研究,以阐明家蚕SOCS的作用机制,特别是在家蚕抗病毒的固有免疫机制中的作用。
