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

Epilepsia, 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.

mGlu5 receptors and cellular prion protein mediate amyloid-β-facilitated synaptic long-term depression in vivo

Nature Communications, 2014
NMDA-type glutamate receptors (NMDARs) are currently regarded as paramount in the potent and selective disruption of synaptic plasticity by Alzheimer’s disease amyloid β-protein (Aβ). Non-NMDAR mechanisms remain relatively unexplored.

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

Epilepsia, 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 ...

Localization and role of metabotropic glutamate receptors subtype 5 in the gastrointestinal tract

World Journal of Gastroenterology, 2017
Metabotropic glutamate receptor subtype 5 (mGluR5) is a Group I mGlu subfamily of receptors coupled to the inositol trisphosphate/diacylglycerol pathway. Like other mGluR subtypes, mGluR5s contain a phylogenetically conserved, extracellular orthosteric binding site and a more variable allosteric binding site, located on the heptahelical transmembrane ...

Central Amygdala Metabotropic Glutamate Receptor 5 in the Modulation of Visceral Pain [PDF]

The Journal of Neuroscience, 2012
Painful bladder syndrome is a debilitating condition that affects 3–6% of women in the United States. Multiple lines of evidence suggest that changes in CNS processing are key to the development of chronic bladder pain conditions but little is known regarding the underlying cellular, molecular, and neuronal mechanisms. Using a mouse model of distention-

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

Journal 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

The 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,

A Single In Vivo Exposure to Cocaine Abolishes Endocannabinoid-Mediated Long-Term Depression in the Nucleus Accumbens

Journal of Neuroscience, 2004
In the nucleus accumbens (NAc), a key structure to the effects of all addictive drugs, presynaptic cannabinoid CB1 receptors (CB1Rs) and postsynaptic metabotropic glutamate 5 receptors (mGluR5s) are the principal effectors of endocannabinoid (eCB ...

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?
