Bilirubin does not modulate ionotropic glutamate receptors or glutamate transporters.

Ionotropic Glutamate Receptors and their Role in Neurological Diseases

Glutamate is extensively and relatively uniformly distributed in the central nervous system (CNS) and its effects mediated by two distinct groups of receptors including Ionotropic and metabotropic glutamate receptors. Concentration of glutamate in the nervous system is much higher than in other tissues. Glutamate receptors play an important role in synaptic transmission, neural plasticity and n...

P24: The Role of Ionotropic Glutamate Receptors in the Induction of LTP

Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulation. The role of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in excitatory synaptic tran...

Segregated expression of AMPA-type glutamate receptors and glutamate transporters defines distinct astrocyte populations in the mouse hippocampus.

Recent data have suggested the existence of direct signaling pathways between glial cells and neurons. Here we report the coexistence of distinct types of cells expressing astrocyte-specific markers within the hippocampus that display diverse morphological, molecular, and functional profiles. Usage of transgenic mice with GFAP promoter-controlled enhanced green fluorescent protein (EGFP) expres...

Nonvesicular release of glutamate by glial xCT transporters suppresses glutamate receptor clustering in vivo.

We hypothesized that cystine/glutamate transporters (xCTs) might be critical regulators of ambient extracellular glutamate levels in the nervous system and that misregulation of this glutamate pool might have important neurophysiological and/or behavioral consequences. To test this idea, we identified and functionally characterized a novel Drosophila xCT gene, which we subsequently named "gende...
