研究组研究内容及意义

　　1. 重要病原微生物感染和免疫研究
　　机体的免疫应答在控制病原微生物感染中发挥决定性作用，我们应用小鼠感染模型和分子、细胞生物学手段，研究流感病毒、军团菌等重要病原微生物感染后机体的免疫应答特征，免疫细胞尤其是NK细胞在抗感染中的功能及调控机制，为深入揭示抗感染免疫机理及传染性疾病的预防和治疗提供研究基础和新靶标。
　　2. 免疫衰老及其分子机制研究
　　世界人口老龄化趋势日渐严重，而人体的健康卫士-免疫系统随着机体生理性衰老功能逐渐下降，该现象在免疫学上称为免疫衰老。我们主要研究NK细胞随机体衰老而出现发育分化及功能缺陷的分子机制。另外，我们建立了老年小鼠的感染模型，深入研究老年小鼠在病毒感染后的机体免疫应答特性并筛选免疫干预的新药物。
　　3. 病原与宿主互作的研究
　　病毒感染宿主后的结果与病理程度取决于宿主与病毒之间的相互作用和相互制约。宿主防御涉及众多基因、非编码RNA、蛋白质和代谢小分子等各种生物元件组成的调控网络。我们将通过病毒编码蛋白与宿主因子互作的研究，筛选和鉴定新型的宿主抗感染因子，发现病毒-宿主互作的新机理、新规律，为病毒性重要传染病的防治提供新的思路和药物靶点。
