Diverse Subpopulations of Reactive Astrocytes Following Chronic Toxoplasma Infection

Glia, EarlyView.
Toxoplasma infection results in distinct astrocyte subpopulations. Chronically labeled reactive astrocytes appear transcriptionally plastic and can regain acute inflammatory responding and naive homeostatic astrocytic gene patterns in the presence of ongoing neuroinflammation.

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.

Human Neuroepithelial Cells Express NMDA Receptors

BMC Neuroscience, 2003
L-glutamate, an excitatory neurotransmitter, binds to both ionotropic and metabotropic glutamate receptors. In certain parts of the brain the BBB contains two normally impermeable barriers: 1) cerebral endothelial barrier and 2) cerebral epithelial ...

Molecular‐Informed Network Analysis Unveils Fatigue‐Related Functional Connectivity in Parkinson's Disease

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

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,

a main role for metabotropic glutamate receptor 1 in the neuroprotective effect of estrogen

Molecular and Cellular Pharmacology, 2012
Estrogen exerts neuroprotective activity under different experimental conditions through classical nuclear receptors, but mainly receptors expressed at the cell surface. Transducing mechanisms activated by these membrane estrogen receptors in the brain have been intensely investigated and, among others, interaction with G-protein coupled, metabotropic ...

Recent Developments in the Optical Control of Adrenergic Signaling

Medicinal Research Reviews, EarlyView.
ABSTRACT Adrenoceptors (ARs) play a vital role in various physiological processes and are key therapeutic targets. The advent of optical control techniques, including optogenetics and photopharmacology, offers the potential to modulate AR signaling with precise temporal and spatial resolution. In this review, we summarize the latest advancements in the

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.

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]

, 2013
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

AMPK acts as a molecular trigger to coordinate glutamatergic signals and adaptive behaviours during acute starvation

eLife, 2016
The stress associated with starvation is accompanied by compensatory behaviours that enhance foraging efficiency and increase the probability of encountering food.
