LBIS® Leptin-Mouse
LBIS® 小鼠瘦素 ELISA 试剂盒
瘦素(Leptin)是一种分子量为16KD的蛋白质类激素。主要由白色脂肪组织产生,其它组织如褐色脂肪组织、胎盘、卵巢、骨骼肌、胃底部、乳腺上皮细胞、骨髓、下垂体、肝脏等也能检测到。其在大鼠和小鼠中有97%的同源性。瘦素在突变种肥胖小鼠中发现,是通过调节食欲和新陈代谢来参与至能量平衡的一种重要的激素。血液中瘦素的浓度会因为空腹和低热量饮食而降低,但进食后并不会有明显增加,只有肥胖即脂肪组织量增大的情况下才会增加,可反映身体脂肪量。瘦素进入大脑,通过抑制体内下丘脑神经肽Y(NPY)和刺鼠基因相关蛋白(AgRP)表达神经的受体,另外活化体内 α-MSH 表达神经,起到降低食欲,减少进食的作用。但是,对于严重肥胖的人,虽然他们血液中瘦素的浓度很高,但对瘦素有抗性,瘦素并不能发挥抑制食欲的作用。全身性脂肪萎缩病引起的瘦素降低或缺乏,会造成胰岛素抗性、糖尿病、脂肪肝、高甘油三酯血症等疾病。除此之外,瘦素也被认为与对动脉粥样硬化的免疫反应、能量平衡和性周期相关,与肺泡表面活性剂的产生也有关系。
