1脑型和味型代谢性谷氨酸受体的不同功能显示文摘目的 利用脑型及味型mGluR4在体内外的表达 ,检测两种受体结构功能上的差异 ,从而证实它们在信号转导功能上的不同。 方法 将克隆得到的脑型及味型mGluR4分别通过脂质体介导转染CHO细胞。在L MSG和L AP4的作用下 ,检测两种受体的功能。利用WesternBlot及原位杂交技术 ,分别检测它们在体内外的表达。 结果 转染脑型及味型mGluR4的CHO细胞 ,表达两种不同分子量的免疫活性蛋白 ,其中脑型分子量约为 12 0kD而味型约为 6 8kD。在L MSG和L AP4作用下 ,味型mGluR4对刺激物反应的浓度远高于脑型mGluR4。对大鼠脑组织及舌味蕾的原位杂交证明 ,mGluR4在小脑颗粒细胞有很高的表达 ,而在味蕾细胞表达率较低 ,阳性细胞仅占味蕾细胞的 5 %。 结论 味组织中的mGluR4与脑组织中mGluR4在结构和功能上有明显不同。味型mGluR4特异性表达于味蕾细胞 ,在高于脑内的浓度下 ,结合细胞外的谷氨酸 ,通过降低cAMP的浓度引发味觉信号转导。杨慧 徐群渊 Roper S Chandhari N 2002解剖学报2002,33,1:2
