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.
营养过剩会导致线粒体功能障碍，这与肥胖相关并发症有关。肥胖还与心脏氧化应激水平升高有关，而氧化应激会导致心肌功能障碍。克鲁等人最近证实了脂肪细胞衍生的细胞外囊泡（EVs）在心脏氧化应激反应中的关键作用，并揭示了它们对缺血/再灌注损伤具有意想不到的保护作用。
