JCEM:冷诱导的棕色脂肪组织活性改变能改善男性糖代谢

2017-09-29 MedSci MedSci原创

越来越多的证据表明,棕色脂肪组织(BAT)激活对人体葡萄糖和脂代谢的有益影响。目前还不清楚冷诱导的BAT激活是否只影响了胰岛素敏感性,是否还影响了胰岛素分泌。同样,其清除循环脂肪酸(FA)的作用并没有得到充分的探讨。

背景:越来越多的证据表明,棕色脂肪组织(BAT)激活对人体葡萄糖和脂代谢的有益影响。目前还不清楚冷诱导的BAT激活是否只影响了胰岛素敏感性,是否还影响了胰岛素分泌。同样,其清除循环脂肪酸(FA)的作用并没有得到充分的探讨。

目的:本研究旨在探讨冷诱导的BAT激活对胰岛素敏感性及胰岛素分泌的影响,及其对血浆FA的影响。

设计:15名健康男性参与了两个实验条件下的交叉平衡重复研究。使用水灌服使受试者暴露于适宜(22°C)和低温(18.06°C,颤抖的除外)两种环境中。冷诱导BAT激活通过在志愿者子集的[18F] - FDG-PET/CT来定量。研究人员使用Botnia钳夹过程来确定胰腺第一相胰岛素反应(FPIR)和胰岛素敏感性。在整个试验过程中,研究人员采样了激素和代谢产物,具体包括26个特定的血清FA。

结果:冷暴露能诱导BAT激活。在寒冷的血浆中,去甲肾上腺素和多巴胺浓度增加。外周葡萄糖摄取和胰岛素敏感性显著提高了20%,而FPIR保持稳定。焦油酸(C24:0)的浓度的增加,而二十碳一烯酸(c20:1n9)、神经酸(c24:1n9),和山嵛酸(C22:0)的水平下降。

结论:冷暴露可诱导人类交感神经系统活动和BAT新陈代谢,从而改善葡萄糖代谢而不影响胰腺胰岛素分泌。此外,BAT的激活与改变循环中不同的Fas浓度有关。这些数据支持这样一个概念,即人类BAT代谢对机体葡萄糖和脂质有着非常重要的协调作用。
