Abstract: BACKGROUND: There are a complex regulatory mechanism and extensive relationship between intestinal flora and brown adipose tissue. However, the mechanism has not yet been clarified.
OBJECTIVE: To reveal the potential relationship between brown adipose tissue and intestinal flora and to provide experimental ideas for further research.
METHODS: The first author used the computer to search for relevant articles published from January 1, 1994 to June 1, 2020 in PubMed, WanFang, VIP, and CNKI. The search terms included “brown adipose tissue, intestinal flora, obesity, peroxisome proliferator-activated receptor family” in English and Chinese, respectively. The author further screened, analyzed, summarized the relevant contents of the included literatures, and finally included 38 articles for final review.
RESULTS AND CONCLUSION: The imbalance of intestinal flora can influence peroxisome proliferator-activated receptors (PPARs), and PPARs have an impact on the metabolism of brown adipose tissue and thereupon regulate obesity. PPARα, PPARβ and PPARγ are all related to adipose metabolism and can be activated by corresponding activators to promote the expression of brown adipose tissue. PPARγ is most closely related to the intestinal flora and brown adipose tissue. Changes in intestinal flora metabolism can up-regulate the expression of PPARγ, thus activating brown adipose tissue to achieve the purpose of weight loss. Regulating the relationship between the intestinal flora and brown adipose tissue can be used as a therapeutic strategy for obesity. Overall, there is a great prospect for developing anti-obesity drugs based on brown adipose tissue and PPARs signaling pathway.
