摘要
Objective Puerarin (PU) is a natural compound that exhibits limited oral bioavailability but has shown promise in the treatment of atherosclerosis (AS). However, the precise mechanisms underlying its therapeutic effects remain incompletely understood. This study aimed to investigate the effects of PU and its mechanisms in mitigating AS in both mice and humans. Design The impact of PU on AS was examined in ApoE −/− mice fed a high-fat diet (HFD) and in human patients with carotid artery plaque. To explore the causal link between PU-associated gut microbiota and AS, faecal microbiota transplantation (FMT) and mono-colonisation of mice with Prevotella copri ( P. copri ) were employed. Results PU alleviated AS by modulating the gut microbiota, as evidenced by alterations in gut microbiota composition and the amelioration of AS following FMT from PU-treated mice into ApoE −/− mice fed HFD. Specifically, PU reduced the abundance of P. copri , which exacerbated AS by producing trimethylamine (TMA). Prolonged mono-colonisation of P. copri undermines the beneficial effects of PU on AS. In clinical, the plaque scores of AS patients were positively correlated with the abundance of P. copri and plasma trimethylamine-N-oxide (TMAO) levels. A 1-week oral intervention with PU effectively decreased P. copri levels and reduced TMAO concentrations in patients with carotid artery plaque. Conclusion PU may provide therapeutic benefits in combating AS by targeting P. copri and its production of TMA. Trial registration number ChiCTR1900022488.
