Heptahelical domain of metabotropic glutamate receptor 5 behaves like rhodopsin-like receptors [PDF]

Proceedings of the National Academy of Sciences, 2003
Although agonists bind directly in the heptahelical domain (HD) of most class-I rhodopsin-like G protein coupled receptors (GPCRs), class-III agonists bind in the extracellular domain of their receptors. Indeed, the latter possess a large extracellular domain composed of a cysteine-rich domain and a Venus flytrap module.

Ionotropic glutamate receptors and their implications in cancer and cancer therapeutics

Biomedical and Biotechnology Research Journal, 2021
Glutamine, an excitatory neurotransmitter, is necessary for physiological as well as pathological processes. Other than neuronal disorders and/or cancers, glutamate receptors have also been associated with an array of other malignancies. The metabotropic

Potential neuroprotective and therapeutic agents and their mechanisms for irradiation‐induced brain injury

Ibrain, EarlyView.
In this review, agents such baicalein, troxerutin, epigallocatechin gallate, quercetin, melatonin, valproic acid, lithium, neurosteroid progesterone, as well as minocycline have been implicated as neuroprotective agents for irradiation‐induced neurological deficits. Also, agents such as glucocorticoids, methylphenidate, vitamin E, bisdemethoxycurcumin,

Blunted Cystine–Glutamate Antiporter Function in the Nucleus Accumbens Promotes Cocaine-induced Drug Seeking [PDF]

, 2008
Repeated cocaine alters glutamate neurotransmission, in part, by reducing cystine–glutamate exchange via system xc−, which maintains glutamate levels and receptor stimulation in the extrasynaptic compartment.

Fluorescent and photo-oxidizing TimeSTAMP tags track protein fates in light and electron microscopy. [PDF]

, 2012
Protein synthesis is highly regulated throughout nervous system development, plasticity and regeneration. However, tracking the distributions of specific new protein species has not been possible in living neurons or at the ultrastructural level ...

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

iNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Conformational diversity in class C GPCR positive allosteric modulation

Nature Communications
The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate.

N-acetyl-cysteine, a drug that enhances the endogenous activation of group-II metabotropic glutamate receptors, inhibits nociceptive transmission in humans. [PDF]

, 2015
Emerging research seeking novel analgesic drugs focuses on agents targeting group-II metabotropic glutamate receptors (mGlu2 and mGlu3 receptors). N-Acetylcysteine (NAC) enhances the endogenous activation of mGlu2/3 receptors by activating the glial ...

The ketogenic diet alters microbiome‐metabolome profiles to improve West syndrome therapy

Pediatric Investigation, EarlyView.
The ketogenic diet alleviates West syndrome by reshaping gut microbiota (increasing Bacteroides, Parabacteroides, and reducing Escherichia and Bifidobacterium), and modulating metabolites—including anticonvulsant lipids (e.g., capric acid), suppressed harmful lipids (e.g., 2‐methylbutyroylcarnitine), and amino acids and analogs (e.g., 3‐sulfinoalanine)—

Pharmacological treatments inhibiting levodopa-induced dyskinesias in MPTP-lesioned monkeys: brain glutamate biochemical correlates

Frontiers in Neurology, 2014
Antiglutamatergic drugs can relieve Parkinson’s disease (PD) symptoms and decrease L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesias (LID).
