458-嗅觉受体Olfr110调控糖脂代谢机制研究

from 聊聊Sci

这项研究揭示了嗅觉受体 Or5v1/Olfr110 在调节机体代谢平衡中的关键作用,发现其能感应由鱼油成分转化而来的内源性脂质分子 12(S)-HEPE。研究人员通过创新的 ARIG 技术鉴定了该受体,并证实其在肝脏中通过 Gs-cAMP-PKA-ATF2 信号通路促进关键代谢基因的表达,从而改善肥胖引发的胰岛素抵抗和脂肪肝。实验表明,人体内的该脂质水平与 体重指数 (BMI) 呈负相关,且该受体功能的缺失会导致能量代谢障碍。此外,通过 人工智能辅助筛选,研究团队开发出了一种名为 HOR1-C59 的高效合成激动剂。在动物模型中,该化合物能显著降低高脂饮食带来的体重增加,并提高糖耐量,展现了通过靶向非鼻组织嗅觉受体治疗代谢性疾病的巨大潜力。这种新型药物设计策略为肥胖及相关代谢紊乱的临床干预提供了全新的研究方向。References: Ge X Y, Cheng J, Zhang L J, et al.
