Effect of Marked Weight Loss on Adipose Tissue Biology in People With Obesity and Type 2 Diabetes
Authors' conclusion
These findings suggest that weight loss increases insulin sensitivity in people with obesity and type 2 diabetes by modifying adipose tissue biology, with concomitant alterations in circulating PAI-1, leptin, HMW adiponectin, and sEV microRNAs.
Study context
- Population
- Adults with obesity and T2D
- Participants
- 10 adults
- Comparison
- After vs before marked weight loss
- Outcome
- Adipose tissue biology and adipose tissue-related plasma factors after weight loss
Methodological detailsbefore-and-after weight loss, hyperinsulinemic-euglycemic clamp
- Before-and-after weight loss
- Hyperinsulinemic-euglycemic clamp
Main finding
As reported in the abstract
- Decreased adipose tissue expression of genes related to extracellular matrix remodeling
- Decreased adipose tissue expression of SERPINE 1 (encodes PAI-1)
- No decrease in adipose tissue immune cell content or expression of inflammation genes
- Decreased adipose tissue ceramide content
- Decreased plasma PAI-1 and leptin; increased plasma high-molecular weight (HMW) adiponectin
- Decreased plasma small extracellular vesicle (sEV) concentration and sEV content of microRNAs proposed to inhibit insulin action; completely reversed inhibitory effect of plasma sEVs on insulin signaling in myotubes
- Weight loss 16-20%; >50% increase in whole-body insulin sensitivity
