摘要：
Bifidobacterium bifidum has been shown to enhance hepatic mitochondrial β-oxidation and improve metabolic dysfunction-associated fatty liver disease (MAFLD) in a rat model. The study demonstrated significant reductions in serum triglycerides and cholesterol levels, alongside improvements in liver structure and function. Mechanistically, B. bifidum modulates key genes involved in fatty acid metabolism, suggesting its potential as a therapeutic strategy for MAFLD. Further research is needed to explore strain-specific effects and long-term outcomes.
