Abstract

gamma-D-Glutamylglycine (DGG) influence on kainate- and quisqualate-activated currents in the Purkinje neurons from rat cerebellum was investigated. DGG caused a parallel shift of concentration dependences of kainate-activated current and a transient component of quisqualate-activated current to the right. Concentration dependence of the stationary component of quisqualate-activated current was shifted to the right by DGG and simultaneously its cooperativity decreased.

摘要

研究了γ-D-谷氨酰甘氨酸(DGG)对大鼠小脑浦肯野神经元中由海人藻酸和quisqualate激活的电流的影响。DGG使海人藻酸激活电流以及quisqualate激活电流的瞬态成分的浓度依赖性平行右移。DGG使quisqualate激活电流的稳态成分的浓度依赖性右移,同时其协同性降低。
