Though glutamate is present in all neurons, only a few are glutamatergic, releasing glutamate as their neurotransmitter. (org.es)
These neurons are believed to release GABA, not glutamate, as their neurotransmitter (Yazulla, 1986), suggesting the weak glutamate labeling reflects the pool of metabolic glutamate used in the synthesis of GABA. (org.es)

Receptor3
The aim of the present study was to investigate the expression of several glutamate receptor 11967625 subunits and calmodulin kinase IIa (CaMKIIa) in the CA1, CA2/3 and dentate gyrus (DG) subregions of the hippocampus, at various time points following BVD, using western blotting. (bet-bromodomain.com)
For the 6 month time point, BVD or sham animals were divided into those with or without spatial forced alternation in T maze training (n = 7 or 6 for each group, respectively), to determine whether spatial learning experience had any effect on hippocampal glutamate receptor expression.

Neurons4
Using immunocytochemical techniques, neurons containing glutamate are identified and labeled with a glutamate antibody. (org.es)
Glutamate incorporated into Muller cells is rapidly broken down into glutamine, which is then exported from glial cells and incorporated into surrounding neurons (Pow and Crook, 1996). (org.es)
The resulting ATPOS complex binds to neurons in cerebral cortex of living mice, and clearly visualized a concentrically propagating wave of extracellular ATP release in response to electrical stimulation. (elifesciences.org)
When glutamate delivers a signal between two neurons that haven't spoken before, the activity primes the pump. (additudemag.com)
Transporters2
Glutamate transporters are essential players in glutamatergic neurotransmission in the brain, where they maintain extracellular glutamate below cytotoxic levels and allow for rounds of transmission. (elifesciences.org)
Briefly, the transporters are homotrimers with each protomer consisting of a centrally located scaffold or trimerization domain and a peripheral transport domain that harbors the L-aspartate (L-asp) and three sodium (Na + ) ions binding sites. (elifesciences.org)
Plasma membrane2
Glutamate is incorporated into these cell types through a high affinity glutamate transporter located in the plasma membrane. (org.es)
