肥胖及其伴随的代谢紊乱是我们这个时代面临的巨大公共卫生挑战。最近的证据表明,代谢组织中炎症的发作与肥胖与胰岛素抵抗和2型糖尿病有病理联系。在这篇综述中,我们简要总结了现有的文献,特别关注组织相关巨噬细胞在代谢性炎症启动中的核心作用。我们认为,肥胖和代谢综合征不是简单的炎症性疾病,而是巨噬细胞激活的紊乱,同时伴有代谢协调的丧失。因此,肥胖的后遗症与有害炎症的存在一样,都是巨噬细胞阳性影响丧失的产物。这一结论的治疗意义是深远的,因为它们表明,药物靶向巨噬细胞激活,而不是单纯的炎症,可能有效治疗这种全球流行病。
Obesity and its attendant metabolic disorders represent the great public health challenge of our time. Recent evidence suggests that onset of inflammation in metabolic tissues pathogenically links obesity to insulin resistance and type 2 diabetes. In this review, we briefly summarize the extant literature with special attention to the central role of the tissue-associated macrophage in the initiation of metabolic inflammation. We argue that rather than simple inflammatory disease, obesity and metabolic syndrome represent derangements in macrophage activation with concomitant loss of metabolic coordination. As such, the sequelae of obesity are as much products of the loss of positive macrophage influences as the presence of deleterious inflammation. The therapeutic implications of this conclusion are profound because they suggest that pharmacologic targeting of macrophage activation, rather than purely inflammation, might be efficacious in treating this global epidemic.
