Abstract:

用原位杂交与免疫组织化学相结合的方法研究了5头三元杂交仔猪前脑内leptin长型受体mRNA与神经肽Y(NPY)免疫反应阳性物质的共存关系。实验结果表明,leptin长型受体mRNA和NPY免疫反应阳性神经元分布于下丘脑漏斗核和前室周核、海马、杏仁核及大脑皮质。上述结构内一些表达leptin长型受体mRNA的神经元也含有NPY免疫反应阳性物质,即leptin长型受体与NPY共存于同一神经元内。提示leptin可能通过下丘脑漏斗核和室周核以及边缘系统的海马和杏仁核,甚至大脑皮质中表达leptin长型受体mRNA的NPY免疫反应阳性神经元调节动物的摄食、能量代谢、生长和繁殖等活动。
