Adipocyte extracellular vesicles: rescuers of cardiac mitochondrial stress

Nutrient excess induces mitochondrial dysfunction, which participates in obesity-related complications. Obesity also associates with high cardiac oxidative stress, which contributes to myocardial dysfunction. Crewe et al. recently evidenced the pivotal role of adipocyte-derived extracellular vesicles (EVs) in cardiac oxidative stress responses and revealed their unexpected protective effect against ischemia/reperfusion injury.

Automated summary

Research shows that nutrient excess leads to mitochondrial dysfunction, contributing to obesity-related complications, while adipocyte-derived extracellular vesicles play a protective role against cardiac oxidative stress.
