摘要： Aims Probiotics have been proved to be strongly linked to the occurrence and progression of atherosclerosis. This study aimed to investigate the improved effects and mechanisms underlying a potential probiotic, Weizmannia coagulans JA845, on atherosclerosis. Methods and Results Male Sprague-Dawley rats supported on a high-fat diet with vitamin D3 supplementation were subjected to W. coagulans JA845 treatment. W. coagulans JA845 obviously alleviated histological abnormalities of the abdominal aorta. After 6 weeks of W. coagulans JA845 administration, levels of TG, TC, LDL, ox-LDL, ROS, and MDA in the JA845 group decreased significantly, and those of HDL, GSH-Px, and SOD were markedly elevated. Treatment with W. coagulans JA845 also inhibited the secretion of ICAM-1 and VCAM-1 and regulated the plasma NO and eNOS content. In brief, administration of W. coagulans JA845 promoted the expression of the SIRT3/SOD2/FOXO3A pathway, inhibited the lipid metabolism pathway, SREBP-1c/FAS/DGAT2, and suppressed the JNK2/P38 MAPK/VEGF pathway implicated in endothelial injury. Conclusions These results indicated W. coagulans JA845 improved atherosclerosis by regulating lipid metabolism, antioxidative stress, and protecting against endothelial injury.
