Inhibition of Vesicular Glutamate Uptake by Rose Bengal-Related Compounds: Structure–Activity Relationship
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-03)
Synaptic vesicular accumulation of glutamate is a vital initial step in glutamate transmission. We have previously shown that Rose Bengal, a polyhalogenated fluorescein analog, is a potent inhibitor of glutamate uptake ...
Phencyclidine-like catalepsy induced by the excitatory amino acid antagonist DL-2-amino-5-phosphonovalerate
(Elsevier, 1986-03)
This study presents experimental evidence for the mediation of a behavioral effect of phencyclidine-like drugs by inhibition of neurotransmission at excitatory synapses utilizing N-methyl-aspartate (NMA) receptors by showing ...
A rapid attenuation of muscarinic agonist stimulated phosphoinositide hydrolysis precedes receptor sequestration in human SH-SY-5Y neuroblastoma cells
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-05)
Agonist occupancy of muscarinic cholinergic receptors in human SH-SY-5Y neuroblastoma cells elicited two kinetically distinct phases of phosphoinositide hydrolysis when monitored by either an increased mass of inositol ...
Repeated haloperidol increases both calmodulin and a calmodulin-binding protein in rat striatum
(Elsevier, 1994-12)
Repeated treatment with the antipsychotic drug, haloperidol, leads to an increased behavioral sensitivity to dopamine agonists exhibited upon withdrawal from the drug. An increase in the particulate content of the endogenous ...
Regulation of Myo-Inositol Homeostasis in Differentiated Human NT2-N Neurons
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-05)
We have investigated the possible role of second messengers on inositol homeostasis in NT2-N cells, human central nervous system neurons obtained by terminal differentiation of teratocarcinoma precursors. Uptake of inositol ...
Effect of clonidine on the release of serotonin from the rat hippocampus as measured by microdialysis
(Elsevier, 1992-05-11)
The purpose of the present study is to clarify the effect of clonidine on the release of serotonin from the rat hippocampus in vivo. For this purpose, endogenous serotonin release was measured by brain microdialysis. ...
Accumulated glutamate levels in the synaptic vesicle are not maintained in the absence of active transport
(Elsevier, 1990-03-14)
We have investigated factors which may affect accumulated glutamate levels in synaptic vesicles and glutamate efflux. Agents which dissipate the electrochemical proton gradient resulted in a rapid reduction of steady-state ...
[alpha]2-Adrenoceptor modulation of 5-HT biosynthesis in the rat brain
(Elsevier, 1992-05-11)
The purpose of the present study is to clarify the modulation of the biosynthesis of serotonin (5-HT) via the [alpha]2-adrenoceptors in the brain. For this purpose. 5-hydroxytryptophan (5-HTP) accumulation was determined ...
Glutamate uptake system in the presynaptic vesicle: Glutamic acid analogs as inhibitors and alternate substrates
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-01)
A variety of naturally occurring amino acids, their isomers, and synthetic analogs were tested for their ability to inhibit uptake of [ 3 H]glutamate into presynaptic vesicles from bovine cerebral cortex. Strongest inhibition ...
Ontogeny of glutamate accumulating activity in rat brain synaptic vesicles
(Elsevier, 1989-02-13)
The relationship between the ontogeny of the vesicular glutamate uptake system and synaptogenesis in rats was investigated. For this purpose we have developed a simplified procedure for the preparation of crude synaptic ...
