Exploring Organ‐Specific Extracellular Vesicles in Metabolic Improvements Following Bariatric Surgery in Youth With Obesity
Authors' conclusion
Following VSG, significant changes occur in the liver-enriched mRNA cargo of sEVs. Liver-derived sEVs appear to influence adipose metabolism, whereas adipose-derived sEVs are linked with liver function, suggesting dynamic intertissue cross talk that shapes systemic metabolic outcomes.
Study context
- Population
- Youth with obesity undergoing vertical sleeve gastrectomy (VSG)
- Comparison
- Pre VSG vs 3-6 months post VSG
- Outcome
- Role of organ-specific small extracellular vesicles (sEVs) in metabolic improvements post VSG
- Follow-up
- 3-6 months post VSG
Methodological detailspre-post, sEV RNA sequenced for bioinformatics analyses
- Pre-post
- sEV RNA sequenced for bioinformatics analyses
Main finding
As reported in the abstract
Organ-enriched mRNA cargo in sEVs · post VSG
- Significant reduction of liver-enriched mRNA cargo in small extracellular vesicles (sEVs) post VSG
- No such reduction of adipose-enriched mRNA cargo
- Liver-enriched mRNA cargo correlated with BMI, leptin and resistin 6 months post VSG
- Delta values (post minus pre): adipose-enriched mRNA cargo correlated with markers of liver damage; liver-derived mRNA cargo correlated with branched-chain amino acids
