在各种动物模型中,卡路里限制被认为是唯一能有效延长寿命的实验方案,但其实际机制仍存在争议。肠道菌群已被证明在宿主健康中起着关键作用,其结构主要由饮食决定。本研究表明,终生限制高脂或低脂饮食的热量摄入,而不是自愿运动,显著改变了C57BL/6 J小鼠肠道微生物群的整体结构。热量限制丰富了与寿命正相关的种型,如乳酸菌属低脂饮食,并减少了与寿命负相关的种型。这些热量限制引起的肠道菌群变化伴随着血清脂多糖结合蛋白水平的显著降低,这表明热量限制下的动物可以建立肠道菌群结构平衡的结构,这可能通过减少肠道抗原负荷对宿主的健康有益。
Calorie restriction has been regarded as the only experimental regimen that can effectively lengthen lifespan in various animal models, but the actual mechanism remains controversial. The gut microbiota has been shown to have a pivotal role in host health, and its structure is mostly shaped by diet. Here we show that life-long calorie restriction on both high-fat or low-fat diet, but not voluntary exercise, significantly changes the overall structure of the gut microbiota of C57BL/6 J mice. Calorie restriction enriches phylotypes positively correlated with lifespan, for example, the genusLactobacilluson low-fat diet, and reduces phylotypes negatively correlated with lifespan. These calorie restriction-induced changes in the gut microbiota are concomitant with significantly reduced serum levels of lipopolysaccharide-binding protein, suggesting that animals under calorie restriction can establish a structurally balanced architecture of gut microbiota that may exert a health benefit to the host via reduction of antigen load from the gut.
