GABA<sub>B</sub> Receptors Mediate Intracellular Calcium Release in Astrocytes of the Prefrontal Cortex. [PDF]

open access: yesEur J Neurosci
We took advantage of GLAST‐promoter driven GCaMP6s expression in astrocytes to study Ca2+ signaling in astrocytes of the young adult prefrontal cortex in response to GABA with confocal Ca2+ imaging. The results show that GABA induces Ca2+ signaling via the stimulation of the metabotropic GABAB receptor in astrocytes.

A PI3K-mediated negative feedback regulates Drosophila motor neuron excitability [PDF]

open access: yes, 2008
Negative feedback can act as a homeostatic mechanism to maintain neuronal activity at a particular specified value. At the Drosophila neuromuscular junction, a mutation in the type II metabotropic glutamate receptor gene (mGluRA) increased motor neuron ...

Performance of cryptogenic new onset refractory status epilepticus score in a Brazilian cohort after testing for antineuronal antibodies with tissue‐based and cell‐based assays

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to describe a case series of Brazilian new onset refractory status epilepticus (NORSE) patients and evaluate the sensitivity and specificity of a clinical score to predict cryptogenic etiology (c‐NORSE score) after autoimmune encephalitis (AE) testing.

Therapeutic Targeting of the α7 Nicotinic Receptor: Challenges and Prospects for Cognitive Improvement in Alzheimer's and Schizophrenia [PDF]

open access: yesBasic Clin Pharmacol Toxicol
ABSTRACT The α7 nicotinic acetylcholine receptor (α7 nAChR) has emerged as a key target for treating cognitive dysfunction in neurological disorders such as Alzheimer's disease (AD) and schizophrenia. α7 nAChRs play essential roles in neurotransmission, neuroinflammation and synaptic plasticity, not only in neurons but also in glial cells, where they ...

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

open access: yes, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

Clioquinol as a new therapy in epilepsy: From preclinical evidence to a proof‐of‐concept clinical study

open access: yesEpilepsia, EarlyView.
Abstract Objective Drug‐resistant epilepsy (DRE) affects >25 million people worldwide and is often associated with neuroinflammation. Increasing evidence links deficiency or malfunctioning of the enzyme phosphoglycerate dehydrogenase (PHGDH), which converts 3‐phosphoglycerate to generate serine and the neurotransmitter glycine, with (drug‐resistant ...

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

open access: yes, 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

Metabotropic glutamate receptors in auditory processing [PDF]

open access: yesNeuroscience, 2014
As the major excitatory neurotransmitter used in the vertebrate brain, glutamate activates ionotropic and metabotropic glutamate receptors (mGluRs), which mediate fast and slow neuronal actions, respectively. Important modulatory roles of mGluRs have been shown in many brain areas, and drugs targeting mGluRs have been developed for the treatment of ...

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Non‐ionotropic NMDAR signalling activates Panx1 to induce P2X4R‐dependent long‐term depression in the hippocampus

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,
