摘要

炎症性心外膜脂肪（EAT）积聚在心肌和冠状动脉周围是心血管疾病的危险因素。胰高血糖素样肽受体激动剂1可改善胰岛素反应，减少胃粘膜厚度。我们的目的是证明西马鲁肽对心外膜促炎脂肪生成的影响，以及对心肌细胞的旁分泌作用。通过实时定量聚合酶链反应、蛋白质组学和代谢分析研究67例接受心内直视手术患者皮下脂肪组织活检或分离基质细胞和EAT。脂肪生成实验和对心房心肌细胞的旁分泌作用确定，semaglutide治疗调节心外膜脂肪生成中的促炎脂肪标志物FABP4和sPLA2，并对心房心肌细胞产生旁分泌作用。

Semaglutide Modulates Proinflammatory Epicardial Adipogenesis With Paracrine Effects on hiPSC-Atrial Cardiomyocytes

Inflamed epicardial fat (EAT) accumulation around the myocardium and coronaries is a risk factor for cardiovascular disease. Glucagon-like peptide receptor-agonists 1 improves the insulin response and reduces EAT thickness. We aimed to demonstrate the effect of semaglutide on proinflammatory epicardial adipogenesis with paracrine effects on cardiomyocytes. Biopsies or isolated stromal cells from subcutaneous adipose tissue and EAT of 67 patients undergoing open-heart surgery were studied by real-time quantitative polymerase chain reaction, proteomics, and metabolic assays. Adipogenesis assay and paracrine effect over atrial cardiomyocytes determined that semaglutide treatment modulates proinflammatory adiposity markers FABP4 and sPLA2 in epicardial adipogenesis with a paracrine effect in atrial cardiomyocytes.
