Extracellular glutamate is not modulated by cannabinoid receptor activity

Scientific Reports
Cannabinoid receptor activation has been proposed to trigger glutamate release from astrocytes located in cortical layer 2/3. Here, we measure the basal concentration of extracellular glutamate in layer 2/3 of mouse somatosensory cortex and find it to be

Probing the ionotropic activity of glutamate GluD2 receptor in HEK cells with genetically-engineered photopharmacology

eLife, 2020
Glutamate delta (GluD) receptors belong to the ionotropic glutamate receptor family, yet they don’t bind glutamate and are considered orphan. Progress in defining the ion channel function of GluDs in neurons has been hindered by a lack of pharmacological

Glutamate receptor ion channels [PDF]

Current Opinion in Neurobiology, 2005
Glutamate receptor ion channels mediate excitatory responses at the majority of CNS synapses. They are the only ligand-gated ion channels for which multiple high-resolution crystal structures have been solved. Highlights of information gained from mechanistic studies based on the crystal structures of their ligand-binding domains include explanations ...

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Permissive role for mGlu1 metabotropic glutamate receptors in excitotoxic retinal degeneration [PDF]

, 2017
Neuroprotection is an unmet need in eye disorders characterized by retinal ganglion cell (RGC) death, such as prematurity-induced retinal degeneration, glaucoma, and age-related macular degeneration.

Adenosine A3 receptor antagonists as anti‐tumor treatment in human prostate cancer: an in vitro study

FEBS Open Bio, EarlyView.
The A3 adenosine receptors (A3ARs) are overexpressed in prostate cancer. AR 292 and AR 357, as A3AR antagonists, are capable of blocking proliferation, modulating the expression of drug transporter genes involved in chemoresistance, ferroptosis, and the hypoxia response, and inducing cell death.

Glutamate Receptors: Desensitizing Dimers [PDF]

Current Biology, 2002
Recent structural studies show, not only how the desensitization of a ligand-gated ion channel with bound agonist can be rationalized in terms of subunit-subunit instability, but also how a previously unknown mode of interaction may provide clues into how the receptor is tetramerically assembled in vivo.

Soman induces endoplasmic reticulum stress and apoptosis of cerebral organoids via the GRP78‐ATF6‐CHOP signaling pathway

FEBS Open Bio, EarlyView.
Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Block of NMDA receptor channels by endogenous neurosteroids: implications for the agonist induced conformational states of the channel vestibule [PDF]

, 2015
N-methyl-D-aspartate receptors (NMDARs) mediate synaptic plasticity, and their dysfunction is implicated in multiple brain disorders. NMDARs can be allosterically modulated by numerous compounds, including endogenous neurosteroid pregnanolone sulfate ...

Glutamate Receptor Channel Kinetics

Biophysical Journal, 1988
Single channel recordings from the locust muscle D-glutamate receptor channel were obtained using glutamate concentrations ranging from 10(-6) to 10(-2) M. Channel kinetics were analyzed to aid in the development of a model for the gating mechanism.
