研究领域：

　　研究补体系统在慢性炎症恶性转化、肿瘤治疗耐药、肿瘤侵袭转移、肿瘤免疫治疗中的作用及机制，并研发补体抑制剂用于疾病治疗。
　　补体系统是先天性免疫的重要组成部分，也是连接先天性免疫与获得性免疫的桥梁。它的基本生理功能为清除细胞碎片，凋亡/死亡细胞和免疫复合物，以及入侵的病原体。另外，还可协调整个免疫和炎症反应，同时功能进一步进化并参与神经突触成熟，血管生成，造血干细胞的迁移动员，组织再生和脂质代谢，广泛参与不同的免疫反应性疾病，炎症，肿瘤，神经退行性疾病等的发生发展。补体系统激活后的酶切产物C3b/iC3b可“标记”待清除的细胞，表达于固有免疫细胞膜表面的相应受体与之结合后可清除这些异常细胞成分；酶切产物C5a是强烈的促炎症因子，也具有很强的趋化因子功能，可在补体激活局部诱发强烈的免疫反应；而补体激活终末阶段形成的膜攻击复合物（Membrane Attack Complex, MAC）则可直接裂解待清除的病原体，也可诱发广泛而复杂的下游信号途径。为了防止补体激活后对正常细胞的误伤效应，宿主细胞膜表面表达有补体膜调控蛋白包括CD59，在补体激活的不同阶段抑制补体的激活而保护宿主细胞。正常生理情况下，补体系统在激活与调控之间维持着精妙的平衡，一旦这种平衡被打破，补体系统激活不足则可能导致感染慢性持续化，而补体过度激活则导致全身或局部的持续性慢性炎症，广泛参与人类疾病包括肿瘤的发生与发展，而补体系统在肿瘤中的作用及机制研究国际上尚处于起步阶段。本实验室基于9种补体成分基因敲除小鼠、相应的补体系统检测平台及补体激动剂和抑制剂，探讨补体系统在慢性炎症恶性转化、肿瘤治疗耐药、肿瘤侵袭转移、肿瘤免疫治疗中的作用及机制，同时研发补体调控剂主要是补体抑制剂用于自身免疫性疾病的治疗。
