Oxygen/Glucose deprivation induces a reduction in synaptic AMPA receptors on hippocampal CA3 neurons mediated by mGluR1 and adenosine A3 receptors [PDF]
, 2011 Hippocampal CA1 pyramidal neurons are highly sensitive to ischemic damage, whereas neighboring CA3 pyramidal neurons are less susceptible. It is proposed that switching of AMPA receptor (AMPAR) subunits on CA1 neurons during an in vitro model of ischemia,

Glia, EarlyView.ABSTRACT The mammalian suprachiasmatic nucleus (SCN) orchestrates daily (circadian) rhythms of physiology and behavior by broadcasting timing cues generated autonomously by its mutually reinforcing network of ~10,000 neurons and ~3000 astrocytes. Although astrocytic control of extracellular glutamate and GABA has been implicated in driving circadian ...

The prion protein regulates glutamate-mediated Ca2+ entry and mitochondrial Ca2+ accumulation in neurons [PDF]
, 2017 The cellular prion protein (PrPC) whose conformational misfolding leads to the production of deadly prions, has a still-unclarified cellular function despite decades of intensive research.

A biophysical network model reveals the link between deficient inhibitory cognitive control and major neurotransmitter and neural connectivity hypotheses in schizophrenia [PDF]
arXiv, 2021 We address a biophysical network dynamical model to study how the modulation of dopamine (DA) activity and related N-methyl-d-aspartate (NMDA) glutamate receptor activity as well as the emerging Pre-Frontal Cortex (PFC) functional connectivity network (FCN) affect inhibitory cognitive function in schizophrenia in an antisaccade task.

Metabotropic Glutamate Receptor Activation in Cerebelar Purkinje Cells as Substrate for Adaptive Timing of the Classicaly Conditioned Eye Blink Response [PDF]
, 1995 To understand how the cerebellum adaptively times the classically conditioned nictitating membrane response (NMR), a model of the metabotropic glutamate receptor (mGluR) second messenger system in cerebellar Purkinje cells is constructed.

Fathoming the kynurenine pathway in migraine: why understanding the enzymatic cascades is still critically important [PDF]
, 2015 Kynurenine pathway, the quantitatively main branch of tryptophan metabolism, has been long been considered a source of nicotinamide adenine dinucleotide, although several of its products, the so-called kynurenines, are endowed with the capacity to ...

Targeting glutamate metabolism in melanoma [PDF]
arXiv, 2019 The glutamate metabotropic receptor 1 (GRM1) drives oncogenesis when aberrantly activated in melanoma and several other cancers. Metabolomics reveals that patient-derived xenografts with GRM1-positive melanoma tumors exhibit elevated plasma glutamate levels associated with metastatic melanoma in vivo. Stable isotope tracing and GCMS analysis determined

Movement Disorders, EarlyView.Abstract Background Fatigue in Parkinson's disease (PD) is a prevalent and debilitating non‐motor symptom. Despite its significant impact on quality of life, the underlying neurochemical and network‐based mechanisms remain poorly understood. Objectives This observational study applied a multimodal imaging approach to explore potential links between the
