Some natural products have been found to have a positive effect on the treatment of Type 2 Diabetes Mellitus (T2DM). The effective mechanism by which these natural products work may be attributed to their ability to alter the gut microbiome. In this study, considering the beneficial properties of resveratrol for T2DM, the mechanism of resveratrol in releasing of T2DM, the correlation between the apparent traits of resveratrol in T2DM mice and the changes in intestinal flora structure were explored. The intervention of resveratrol in different dose did effectively improve the apparent T2DM symptoms in mice, including reduced fasting blood glucose, enhance to both the insulin tolerance and glucose tolerance. Simultaneously, resveratrol can effectively ameliorate the pathological condition of the colon and rectum in T2DM mice, leading to a reduction in intestinal villi swelling and fat vacuoles. The intervention of resveratrol led to changes in the gut flora structure of T2DM mice. Erysipelas and Ileibacterium are crucial taxa of resveratrol involved in maintaining the balance of the gut microbiota. The abundance of Erysipelotrichaceae and Ileibacterium was significantly elevated under the treatment of resveratrol, and the compose of the gut microbiota was more inclined to healthy mice. T2DM symptoms could be alleviated by resveratrol through different mechanisms compared to metformin intervention.
一些天然产物已被发现对2型糖尿病(T2DM)的治疗有积极作用。这些天然产物发挥作用的有效机制可能归因于它们改变肠道微生物群的能力。在本研究中,考虑到白藜芦醇对T2DM的有益特性,探讨了白藜芦醇在缓解T2DM中的作用机制、T2DM小鼠体内白藜芦醇的表观特征与肠道菌群结构变化之间的相关性。不同剂量白藜芦醇的干预有效改善了小鼠的T2DM表观症状,包括降低空腹血糖、增强胰岛素耐受性和葡萄糖耐受性。同时,白藜芦醇可有效改善T2DM小鼠结肠和直肠的病理状况,导致肠绒毛肿胀和脂肪空泡减少。白藜芦醇的干预导致T2DM小鼠肠道菌群结构发生变化。丹毒丝菌属和回肠杆菌属是白藜芦醇参与维持肠道微生物群平衡的关键分类群。在白藜芦醇治疗下,丹毒丝菌科和回肠杆菌属的丰度显著升高,肠道微生物群的组成更倾向于健康小鼠。与二甲双胍干预相比,白藜芦醇可通过不同机制缓解T2DM症状。
