G protein-coupled receptor signalling in astrocytes in health and disease: A focus on metabotropic glutamate receptors [PDF]
Work published over the past 10–15 years has caused the neuroscience community to engage in a process of constant re-evaluation of the roles of glial cells in the mammalian central nervous system.

Possible Role of N-Methyl-D-Aspartate Glutamate Receptors in The Induction of Acrosome Reaction in Human Sperm [PDF]
Objective: Acrosome reaction is a receptor and Ca2+-dependent process. N-Methyl-D- aspartate (NMDA) glutamatereceptors are expressed in the human sperm and are involved in the Ca2+ influx.

Uncoupling of the endocannabinoid signalling complex in a mouse model of fragile X syndrome [PDF]
Fragile X syndrome, the most commonly known genetic cause of autism, is due to loss of the fragile X mental retardation protein, which regulates signal transduction at metabotropic glutamate receptor-5 in the brain.

A glutamate receptor C-tail recruits CaMKII to suppress retrograde homeostatic signaling
Presynaptic homeostatic plasticity adaptively enhances neurotransmitter release following diminished postsynaptic glutamate receptor functionality. Here the authors identify a calcium-independent signaling system where active CaMKII detects a short ...

NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional

Removal of AMPA receptors (AMPARs) from synapses is preceded by transient endocytosis of extrasynaptic AMPARs [PDF]
AMPA receptors (AMPARs) are dynamically regulated at synapses, but the time course and location of their exocytosis and endocytosis are not known. Therefore, we have used ecliptic pHluorin-tagged glutamate receptor 2 to visualize changes in AMPAR surface

Domain-based identification and analysis of glutamate receptor ion channels and their relatives in prokaryotes. [PDF]
Voltage-gated and ligand-gated ion channels are used in eukaryotic organisms for the purpose of electrochemical signaling. There are prokaryotic homologues to major eukaryotic channels of these sorts, including voltage-gated sodium, potassium, and ...

Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

FGF-2 Induces Neuronal Death through Upregulation of System xc- [PDF]
The cystine/glutamate antiporter (system xc-) transports cystine into cell in exchange for glutamate. Fibroblast growth factor-2 (FGF-2) upregulates system xc- selectively on astrocytes, which leads to increased cystine uptake, the substrate for ...

Incentive learning underlying cocaine relapse requires mGluR5 receptors located on dopamine D1 receptor-expressing neurons [PDF]
Understanding the psychobiological basis of relapse remains a challenge in developing therapies for drug addiction. Relapse in cocaine addiction often occurs following exposure to environmental stimuli previously associated with drug taking.
