腺苷激动剂可抑制大鼠齿状回切片中谷氨酸的释放,但不影响γ-氨基丁酸(GABA)的释放;而环磷酸腺苷类似物则可增强谷氨酸的释放,同样不影响GABA的释放。

Abstract

The adenosine agonist 2-chloroadenosine inhibited the K+-induced release of endogenously synthesized [3H]glutamate but not [3H]GABA from slices of rat dentate gyrus. In contrast, the K+-stimulated release of [3H]glutamate was augmented by the adenosine antagonist theophylline and was further enhanced by the cyclic AMP analogue 8-bromo-cyclic AMP in the presence of theophylline.

摘要

腺苷激动剂2-氯腺苷抑制了钾离子诱导的大鼠齿状回切片中内源性合成的[3H]谷氨酸的释放,但不影响[3H]γ-氨基丁酸的释放。相反,腺苷拮抗剂茶碱增强了钾离子刺激的[3H]谷氨酸的释放,并且在茶碱存在的情况下,环磷酸腺苷类似物8-溴环磷酸腺苷进一步增强了这种释放。
