1.老年性痴呆发病机制与防治。老年性痴呆又称阿尔茨海默病(AD),随全球人口老龄化其发病率逐步增高,目前已经成为导致痴呆的最主要病因。AD发病机制不明,防治困难,本研究组主要聚焦于AD发病上游机制的研究,以期为其防治提供新靶点。近年来主要研究兴趣领域如下:1) 环境因素如中枢神经系统锌稳态异常、外周肠道微生物在AD发病中的作用和机制:研究组探讨揭示脑内微量元素锌稳态异常促进AD样tau病变的作用及其机制,发现干预锌失衡可逆转tau蛋白过度磷酸化和聚集;探讨揭示外周幽门螺杆菌感染促进脑内AD样病变的作用和机制。2) 蛋白磷酸酯酶2A(PP2A)的调节及其异常在神经退变中的作用:PP2A活性抑制是AD脑内tau蛋白过度磷酸化的关键促进因素,研究组系统探讨AD脑内PP2A活性下调的上游机制及可能的干预措施,并通过广泛的国际合作寻找候选治疗化合物分子。
2. 抑郁症发病机制与防治。随着工业化进展,抑郁症(MDD)的全球发病率呈显著增高趋势,2018年数据指出全球MDD的年发病率为6%。抑郁症发病机制不明,治疗方法有限。研究组的主要研究兴趣领域为神经可塑性异常在抑郁症中的作用和分子机制,陆续发现揭示了若干调控神经发育和可塑性的关键分子在抑郁症发病中的作用;并以此为干预靶点探索新的抑郁症干预治疗措施。
