The gut microbiota influences atherosclerosis development through microbial metabolites and interactions with lipid pathways. Modulating gut bacteria shows potential for treating this chronic inflammatory vascular disease.
Area of Science:
- Cardiovascular Science
- Microbiology
- Immunology
Background:
- Atherosclerosis is a chronic inflammatory arterial disease.
- Traditionally linked to lipid disorders, lipid-independent pathways are now recognized.
- Emerging evidence implicates the gastrointestinal microbiota in atherosclerosis development.
Purpose of the Study:
- To explore the role of gut microbiota in atherosclerosis.
- To understand the mechanisms linking gut bacteria to vascular inflammation.
- To assess the therapeutic potential of microbiota modulation.
Main Methods:
- Analysis of clinical studies on gut microbiota composition in atherosclerosis patients.
- Investigation of microbial metabolites' impact on vascular inflammation.
- Review of preclinical studies on microbiota-targeted interventions.
Main Results:
- Altered gut microbiota and oral bacteria in the gut are observed in atherosclerosis, cardiovascular disease, and stroke.
- Microbial metabolites like endotoxin and trimethylamine N-oxide promote atherosclerosis; some tryptophan derivatives may be protective.
- Gut microbiota interacts with lipid metabolism, affects lipid absorption/storage, and contributes to vascular aging.
Conclusions:
- The gut microbiota acts as a key regulator of vascular inflammation in atherosclerosis.
- Host-microbe interactions in the gut present future therapeutic targets for atherosclerosis.
- Interventions like prebiotics and probiotics show promise, primarily in preclinical settings.
