Neurotoxicity of Hcy. (A figure that best represents the scope of the paper.) Homocysteine can reduce the tightness of endothelial cell connections, increase vascular permeability, and damage the blood–brain barrier. Homocysteine activates various glutamate receptors on the surfaces of neurons and glial cells, triggering excitotoxicity, promoting the ...

Stimulation of microglial metabotropic glutamate receptor mGlu2 triggers tumor necrosis factor alpha-induced neurotoxicity in concert with microglial-derived fas ligand [PDF]
Activated microglia may be detrimental to neuronal survival in a number of neurodegenerative diseases. Thus, strategies that reduce microglial neurotoxicity may have therapeutic benefit.

Main Points Multi‐omics reveal Annexin‐A2 (A2) and S100a10 (A10) as SCN astrocyte enriched proteins. Disrupting A2‐A10 complex elevates astrocyte Ca2+ and compromises SCN timekeeping. Astrocytic A2‐A10 is a critical control point for SCN network rhythms.

Glutamate Receptor Signaling in Retina Müller Cells: Plausible Role in Neurodegeneration
The retinal network relies on glutamate, the primary excitatory neurotransmitter involved in the visual cycle. Glutamate transactions are carried out by an array of distinct receptors and transporters distributed across both pre- and post-synaptic ...

ABSTRACT Background and Aims Alzheimer's disease (AD), a chronic neurodegenerative disorder, is portrayed by neurocognitive decline in the structure and function of the human brain. Various factors are implicated in the pathogenesis to neuroplasticity alteration in the brain of an individual afflicted with AD.

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study [PDF]
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

Glutamine Metabolism: Molecular Regulation, Biological Functions, and Diseases
Tumor cells adapt to nutrient‐poor environments by altering metabolism to acquire essential nutrients. They convert glutamine into glutamate and α‐ketoglutarate, supporting mTOR activation and sugar biosynthesis. Disruption of mTORC1 signaling is linked to disease, while glutamine and leucine activation promotes cell growth and inhibits autophagy ...
