Metabotropic glutamate receptors are known to act as modulators of (affect the activity of) other receptors. For example, group I mGluRs are known to increase the activity of N-methyl-D-aspartate receptors (NMDARs), [12] [13] a type of ion channel-linked receptor that is central in a neurotoxic process called excitotoxicity.
This energy pathway is upregulated in cancer, which may represent a therapeutic target as cancer cells are thought to be more dependent on glutamine than healthy cells. [24] This especially holds true for specific tumor types that are metabolically dysregulated, such as malignant brain tumors (i.e. glioblastoma) that carry mutations in the IDH1 ...
Glutamatergic means "related to glutamate". A glutamatergic agent (or drug ) is a chemical that directly modulates the excitatory amino acid ( glutamate / aspartate ) system in the body or brain. Examples include excitatory amino acid receptor agonists , excitatory amino acid receptor antagonists , and excitatory amino acid reuptake inhibitors .
NMDA receptors are glutamate-gated cation channels that allow for an increase of calcium permeability. Channel activation of NMDA receptors is a result of the binding of two co agonists, glycine and glutamate. Overactivation of NMDA receptors, causing excessive influx of Ca 2+ can lead to excitotoxicity. Excitotoxicity is implied to be involved ...
The review authors noted that research into the potential brain benefits of GLP-1 medications needs more research but are optimistic about the future of these drugs in how they may boost brain health.
These glutamate receptors are suggested to play a role in modulating gene expression in glial cells, both during the proliferation and differentiation of glial precursor cells in brain development and in mature glial cells. [12] Glutamate receptors serve to facilitate the impact of the neurotransmitter glutamate in the central nervous system.
Glucagon-like peptide-1 receptor agonists (GLP-1) drugs are a class of medications used to manage type 2 diabetes and treat obesity. While many drugs in this class are relatively new, researchers ...
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
