Abstract

Adipose tissue inflammation and dysfunction are considered central in the pathogenesis of obesity-related dysmetabolism, but their role in the rapid metabolic recovery upon obesity reversal is less well defined. We hypothesized that changes in adipose tissue endocrine and paracrine mechanisms may support the rapid improvement of obesity-induced impairment in cellular lipid handling. C57Bl-6J mice were fed either normal chow (NC) or high-fat diet (HFF) for 10 weeks. A dietary obesity reversal group was fed HFF for 8 weeks and then switched to NC for 2 weeks (HFF→NC). Whole-body glucose homeostasis rapidly nearly normalized in the HFF→NC mice (fasting glucose and insulin fully normalized, glucose and insulin tolerance tests reversed 82% to the NC group levels). During 2 weeks of the dietary reversal, the liver was significantly cleared from ectopic fat, and functionally, glucose production from pyruvate, alanine or fructose was normalized. In contrast, adipose tissue inflammation (macrophage infiltration and polarization) largely remained as in HFF, though obesity-induced adipose tissue macrophage lipid accumulation decreased by ~50%, and adipose tissue MAP kinase hyperactivation was reversed. , mild changes in adipose tissue adipocytokine secretion profile were noted. These corresponded to partial or full reversal of the excess cellular lipid droplet accumulation induced by HFF adipose tissue conditioned media in hepatoma or macrophage cells, respectively. We propose that early after initiating reversal of nutritional obesity, rapid metabolic normalization largely precedes resolution of adipose tissue inflammation. Nevertheless, we demonstrate a hitherto unrecognized contribution of adipose tissue to the rapid improvement in lipid handling by the liver and by macrophages.

摘要

脂肪组织炎症和功能障碍被认为是肥胖相关代谢紊乱发病机制的核心,但它们在肥胖逆转后快速代谢恢复中的作用尚不清楚。我们假设脂肪组织内分泌和旁分泌机制的变化可能有助于肥胖诱导的细胞脂质处理受损的快速改善。将C57Bl-6J小鼠喂食正常饲料(NC)或高脂饲料(HFF)10周。一个饮食肥胖逆转组先喂食HFF 8周,然后改为NC 2周(HFF→NC)。HFF→NC小鼠的全身葡萄糖稳态迅速几乎恢复正常(空腹血糖和胰岛素完全恢复正常,葡萄糖和胰岛素耐量试验恢复到NC组水平的82%)。在饮食逆转的2周内,肝脏中的异位脂肪显著清除,并且在功能上,丙酮酸、丙氨酸或果糖的葡萄糖生成恢复正常。相比之下,脂肪组织炎症(巨噬细胞浸润和极化)在很大程度上仍与HFF时一样,尽管肥胖诱导的脂肪组织巨噬细胞脂质积累减少了约50%,并且脂肪组织MAP激酶过度激活得到了逆转。注意到脂肪组织脂肪细胞因子分泌谱有轻微变化。这些分别对应于HFF脂肪组织条件培养基诱导的肝癌或巨噬细胞中过量细胞脂质滴积累的部分或完全逆转。我们提出,在开始营养性肥胖逆转后早期,快速代谢正常化在很大程度上先于脂肪组织炎症的消退。然而,我们证明了脂肪组织对肝脏和巨噬细胞脂质处理快速改善的一种迄今未被认识的贡献。
