更年期与骨质流失和内脏肥胖有关。我们以前已经证明,垂体激素FSH β亚基的多克隆抗体(Ab)增加小鼠的骨量。在这里,我们报告说,这种抗体大幅减少野生型小鼠的脂肪组织,表型遗传FSHR单倍不足。抗体还引起深褐色,增加细胞线粒体密度,激活棕色脂肪组织,并增强产热作用。这些作用是由于Ab与FSHβ特异性结合而阻断其作用的结果。我们的研究揭示了共同治疗肥胖和骨质疏松症的新机会。
Menopause is associated with bone loss and enhanced visceral adiposity. We have shown previously that a polyclonal antibody (Ab) to the β-subunit of the pituitary hormone Fsh increases bone mass in mice. Here, we report that this Ab sharply reduces adipose tissue in wild type mice, phenocopying genetic Fshr haploinsufficiency. The Ab also causes profound beiging, increases cellular mitochondrial density, activates brown adipose tissue, and enhances thermogenesis. These actions result from the specific binding of Ab to Fshβ to block its action. Our studies uncover novel opportunities for co-treating obesity and osteoporosis.
