The significant increase of free calcium concentration ([Ca2+]i) was found in rat cerebral cortex synaptosomes and hippocampal crude synaptosomal fraction after their exposure to glutamate. But no change of [Ca2+]i was revealed in cerebellar synaptos

Publikováno v: Bulletin of Experimental Biology and Medicine. 129:36-38

Glutamate significantly increased intracellular calcium concentration, enhanced45Ca2+ entry, and activated Na+/Ca2+ exchanger in synaptosomes from rat cerebral cortex. Preincubation with GM1 ganglioside reduced the glutamate-induced increase in intra
