周细胞是在整个微血管系统中普遍存在的壁细胞。它们的主要生理作用是支持内皮细胞,调节微血管血流,并对其微环境中的扰动作出反应。周细胞对2型糖尿病特有的代谢异常敏感,包括血脂异常、高血糖和高胰岛素血症。由于这些异常,晚期糖基化终产物、活性氧、多元醇途径活化和蛋白激酶C亚型活化导致周细胞功能障碍,并导致2型糖尿病许多常见并发症的发病机制。已知周细胞功能障碍是2型糖尿病患者视网膜病变、肾病、神经病变、β细胞功能障碍和外周动脉疾病发病机制的促成因素。治疗应针对周细胞来治疗这些常见的糖尿病并发症。
Pericytes are mural cells that are found ubiquitously throughout the microvasculature. Their main physiological roles are to support endothelial cells, regulate microvascular blood flow, and respond to perturbations in their microenvironment. Pericytes are sensitive to the metabolic abnormalities that are characteristic of type 2 diabetes mellitus, including dyslipidemia, hyperglycemia, and hyperinsulinemia. As a consequence of these abnormalities, advanced glycation end products, reactive oxygen species, polyol pathway activation, and protein kinase C isoform activation cause pericyte dysfunction and contribute to the pathogenesis of many common complications of type 2 diabetes. Pericyte dysfunction is known to be a contributing factor to the pathogenesis of retinopathy, nephropathy, neuropathy, beta cell dysfunction, and peripheral artery disease in people with type 2 diabetes. Therapies should target pericytes to treat these common diabetic complications.
