目前主要从事的研究领域

我们的研究领域包括免疫生物学和免疫药理、心血管生物学和心血管药理、分子细胞生物学和蛋白质组学、受体和信号传导通道的调节机制。本研究室的长期研究目标是研究许多严重威胁公众健康和生命的疾病机制,在深入了解疾病发生发展机制的基础上,开发能够预防和治疗这些疾病的药物。

免疫反应包括先天性免疫反应和获得性免疫反应。先天免疫系统是人体对内源性和外源性致病原产生免疫应答和急性炎症反应的第一道防线。先天免疫系统主要由补体、多形核细胞、天然杀伤细胞(NK)树突状细胞(DC)等组成。获得免疫系统主要由白细胞和淋巴细胞介导,包括体液免疫反应和细胞免疫反应。体液免疫反应由B淋巴细胞分泌的抗体介导,细胞免疫由T淋巴细胞分泌的细胞因子介导。T细胞包括细胞毒T(Tc)、帮助T(Th)和调节T(Treg)细胞。先天性免疫系统的几个成分通过不同的机制促使抗原提呈细胞特别是树突状细胞(DC)成熟,决定了获得性免疫系统中B淋巴细胞发育和T淋巴细胞分泌的Th1、Th2细胞因子的极化方向。获得性免疫反应的Th1或Th2细胞因子极化方向改变是许多疾病例如组织纤维化和组织重构的关键因素。目前,我们的研究方向包括具有抗原呈递功能的DC细胞和NK细胞之间的相互作用;DC细胞和T细胞之间的相互作用特别是DC细胞发育成熟及活性是如何决定Th1,Th2和调节性T细胞(Treg)发育方向。

组织纤维化是多种严重威胁人类健康疾病的基本病理改变,累及人体几乎所有器官和系统,是许多疾病致残、致死的主要原因。目前没有有效治疗组织纤维化疾病的药物。我们正在使用不同的组织纤维化动物模型和细胞模型,从免疫学角度研究组织纤维化发生和发展的病原生物学和病理生理学机制。我们的目的是在深入理解纤维增生性疾病分子机制基础上,开发抗组织纤维化药物。因此,本课题具有重要的理论和实际意义。

心血管疾病严重危害人类的健康。全世界许多国家心血管疾病都是威胁人类健康的“第一杀手”,每年有一千七百万人(1/3全球死亡率)死于心血管疾病。我们的研究方向包括研究心血管疾病的病原学和病理机制;心血管疾病发病过程中的信号传导机制,特别是G蛋白偶合受体和生长因子受体介导的细胞生物学反应中的信号传导机制和真核基因表达调控机制。在此基础上,发现治疗心血管疾病的新药靶,开发治疗心血管疾病药物。
