962-调控肠-肝-脑轴代谢的工程共生菌

from 聊聊Sci

这份研究展示了通过基因工程技术改造的植物乳杆菌,能够有效调节肠-肝-脑轴的代谢紊乱,从而治疗肝性脑病。研究人员设计了两种菌株:一种可吸收氨并合成支链氨基酸,另一种则能增强谷氨酰胺的利用以抑制氨的产生。在动物模型中,这些工程菌显著降低了血液与大脑中的氨含量,并改善了焦虑及认知功能障碍。相比临床常用药物利福昔明,该疗法在保持肠道菌群多样性方面表现更优,且在停药后可被迅速清除。这一进展证明了活体生物治疗药物作为可编程平台,在恢复人体代谢平衡和治疗复杂神经疾病方面的巨大潜力。References:Aggarwal N, Shen H, Lee L T, et al.
