内皮细胞超越了所有临床学科,是每个器官系统功能的关键。内皮的一个重要但知之甚少的作用是它根据器官需要控制能量供应的运输的能力。脂肪酸(FA)特别代表被许多组织利用的关键能量来源,但是其利用必须被严格调节以避免过量积累的潜在有害后果,包括胰岛素抗性。最近的研究已经确定了涉及血管内皮生长因子B、过氧化物酶体增殖物激活受体-γ和肽配体apelin的关键内皮信号传导机制,这些机制对FA转运的内皮调节至关重要。在这里,我们讨论了这些信号通路调节这一关键内皮功能的机制。
The endothelium transcends all clinical disciplines and is key to the function of every organ system. A crucial, but poorly understood role of the endothelium is its ability to control the transport of energy supply according to organ needs. Fatty acids (FAs) in particular represent a key energy source that is utilized by a number of tissues, but whose utilization must be tightly regulated to avoid potentially deleterious consequences of excess accumulation, including insulin resistance. Recent studies have identified key endothelial signaling mechanisms involving vascular endothelial growth factor B, peroxisome proliferator-activated receptor-γ, and the peptide ligand apelin, that are critical to endothelial regulation of FA transport. Here we discuss the mechanisms by which these signaling pathways regulate this key endothelial function.
