1. GABA传导系统异常在阿尔茨海默症发病过程中的作用机制
γ-氨基丁酸（GABA）是中枢神经系统中主要的抑制性神经递质，对控制维持中枢神经系统的兴奋-抑制平衡至关重要，GABA的功能性失调会导致诸如癫痫，睡眠障碍，自闭症和精神分裂症等多种中枢系统疾病。此外，我们最新的研究还发现，GABA与阿尔茨海默症（Alzheimer’s disease, AD）也密切相关。我们首次发现了在AD模型小鼠大脑中的应激性星型胶质细胞，也可以释放GABA，从而导致大脑过度抑制，影响AD小鼠海马区LTP的诱导和学习记忆。小分子特异性地抑制胶质细胞GABA的释放（Nature Communications，2014）或GABA合成酶基因的单倍体不足（Molecular Neurodegeneration， 2017），都可以显著性的改善AD的症状，增强学习记忆。未来，我们将继续深入研究应激性星形胶质细胞释放的GABA对不同脑区和不同类型神经元活性及神经网络活动的影响，揭示其导致认知障碍的神经机制，并研发相应的干预治疗策略，进而达到改善AD模型小鼠的认知能力，为老年痴呆症的干预治疗提供新的思路。
2. 原位神经再生基因治疗的基础开发和优化
人类大脑约有860亿神经元，同时也有数量相当的胶质细胞。神经元缺乏再生能力，胶质细胞则能通过分裂而再生。中枢损伤或病变通常伴随着神经元的不可逆丢失，同时还常有胶质细胞的异常增生。基于这些病理特征，我们提出是否可以通过细胞重编程技术，进而将增生的胶质细胞改造成为功能性的神经元，从而达到神经再生的目标，为神经再生这一世界性的医学难题提供新思路。然而实现原位胶质细胞重编程困难重重，例如我们近期发现Olig2作为一种“诱导”性的阻力转录因子，抑制了星形胶质细胞向神经元的转分化(Nature Communications, 2026)。为了克服细胞重编程的障碍，我们需要不断优化细胞重编程的策略，实现高效的原位神经再生，从而治疗相关脑疾病。迄今，我们的研究已经证实可以在老年痴呆症（Cell Stem Cell，2014；Advanced Science, 2025）、亨廷顿舞蹈症（Nature Communications，2020）和脑卒中（Molecular Therapy, 2020）小鼠大脑中，将胶质细胞原位转化为功能性的神经元，并取得了显著的治疗效果。目前，我们正在优化在体细胞重编程技术，提高胶质细胞转化为神经元的效率，扩大胶质细胞转化为神经元的脑区范围，定向再生特定亚型的神经元（如GABA能神经元， Nature Communications，2020），以及减少重编程基因递送策略的毒副作用等，开发实用性的原位神经再生基因治疗，造福广大患者。
