脂肪组织不能扩张,导致招募新脂肪细胞的能力耗尽,这可能是肥胖和胰岛素抵抗之间联系的基础。脂肪细胞来源于间充质前体,其定向和分化沿着脂肪细胞谱系受到严格调控。这些调节因子介导脂肪细胞之间的相互作用,确保脂肪细胞的生长和分化与能量储存需求相结合。WNT家族的自分泌和旁分泌生长因子调节成人组织的维持和重塑,因此,非常适合介导脂肪细胞通讯。事实上,最近的几份报告,总结在这篇评论中,暗示WNT信号在调节脂肪形成。因此,操纵WNT通路来改变脂肪细胞组成,构成了对抗肥胖相关代谢并发症的有吸引力的药物开发目标。
An inability of adipose tissue to expand consequent to exhausted capacity to recruit new adipocytes might underlie the association between obesity and insulin resistance. Adipocytes arise from mesenchymal precursors whose commitment and differentiation along the adipocytic lineage is tightly regulated. These regulatory factors mediate cross-talk between adipose cells, ensuring that adipocyte growth and differentiation are coupled to energy storage demands. The WNT family of autocrine and paracrine growth factors regulates adult tissue maintenance and remodelling and, consequently, is well suited to mediate adipose cell communication. Indeed, several recent reports, summarized in this review, implicate WNT signalling in regulating adipogenesis. Manipulating the WNT pathway to alter adipose cellular makeup, therefore, constitutes an attractive drug-development target to combat obesity-associated metabolic complications.
