Abstract | BACKGROUND: MATERIALS AND METHODS: RESULTS: Agonist treatment (0.01-1000 nm) of GT1-1 neurons resulted in dose-dependent increases in intracellular calcium. SHU-9119 (0.01-1000 nm) abolished the calcium response. Treatment with U73122 (10 microm) attenuated the calcium response, while U73433 (10 microm) had minimal effect. 2APB (200 microm) inhibited the calcium transient, and the use of calcium-free buffer did not affect the amplitude of the calcium spike. CONCLUSIONS:
