研究领域

在炎症与癌症的病理过程中，淋巴细胞与癌细胞的运动是其中的关键步骤。而决定这些细胞运动的一类重要分子是细胞粘附分子(Cell Adhesion Molecule，CAM)，其中整合素(integrin)家族是最重要的一类粘附分子。在细胞运动的过程中，整合素的功能受到动态的、精确的调控。而病理条件下的整合素功能会发生紊乱。我们的研究兴趣点是与炎症和癌症相关的整合素的功能调控及其分子机制，了解整合素在炎症细胞迁移与癌细胞发生、发展和转移过程中的作用机制，寻找炎症与癌症的新疗法。通过研究细胞粘附分子与其配体的识别、结合及其所介导的信号转导，找到调控细胞粘附分子功能的关键点，进而通过控制细胞粘附分子的功能而达到治疗炎症与癌症的目的。本实验室的主要研究方向包括： 1、整合素在免疫细胞运动中的作用机制及其自身免疫疾病中的作用机理； 2、免疫细胞与肠道干细胞和菌群的互作及其在肠道稳态中的作用机理； 3、整合素及趋化因子在肿瘤免疫中的作用机制； 4、整合素在肿瘤发生、发展与转移中的作用机制； 5、以整合素为靶的药物筛选以及肿瘤的早期诊断方法
