Astrocyte-neuron interaction in the substantia gelatinosa of the spinal cord dorsal horn via P2X7 receptor-mediated release of glutamate and reactive oxygen species.
本研究通过脊髓胶状质(SG)切片全细胞膜片钳记录,探讨星形胶质细胞与神经元之间经P2X7受体介导的谷氨酸和活性氧(ROS)释放相互作用。在低Ca2+/无Mg2+外液条件下,ATP和Bz-ATP诱导的内向电流显著增大,且Bz-ATP效应可被选择性P2X7受体拮抗剂A-438079抑制。神经元Bz-ATP电流可被离子型谷氨酸受体拮抗剂A...
