Caffeine, a methylated derivative of xanthine and widely consumed psychoactive substance, acts in several targets in the nervous system. We investigated its role in retinal explants of chick embryo analyzing the role of purinergic receptors in [(3)H]-GABA release induced by d-aspartate (d-asp). d-Asp increases GABA-release 4.5-fold when compared to basal(More)
l-Glutamate and l-aspartate are the main excitatory amino acids (EAAs) in the Central Nervous System (CNS) and their uptake regulation is critical for the maintenance of the excitatory balance. Excitatory amino acid transporters (EAATs) are widely distributed among central neurons and glial cells. GLAST and GLT1 are expressed in glial cells, whereas(More)
Phosphorylation of GluA1, a subunit of AMPA receptors (AMPARs), is critical for AMPAR synaptic trafficking and control of synaptic transmission. cGMP-dependent protein kinase II (cGKII) mediates this phosphorylation, and cGKII knockout (KO) affects GluA1 phosphorylation and alters animal behavior. Notably, GluA1 phosphorylation in the KO hippocampus is(More)
