Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]

open access: yes, 2011
Adaptive forms of synaptic plasticity that reduce excitatory synaptic transmission in response to prolonged increases in neuronal activity may prevent runaway positive feedback in neuronal circuits.

Decoding the Pathophysiology of Autoimmune Diseases—Mechanism, Triggers, and Nanotherapeutics: A Review

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,

Ophelia syndrome with metabotropic glutamate receptor 5 antibodies in CSF [PDF]

open access: yesNeurology, 2013
A 35-year-old man developed progressive memory problems and personality changes over the course of 6 months. This amnesia culminated in overt functional impairment as he began getting lost in familiar places and paid his rent multiple times in one day. He then displayed increased aggression and was admitted to hospital after assaulting a family member.

NMDA Receptor-Dependent Metaplasticity by High-Frequency Magnetic Stimulation

open access: yesNeural Plasticity, 2014
High-frequency magnetic stimulation (HFMS) can elicit N-methyl-D-aspartate (NMDA) receptor-dependent long-term potentiation (LTP) at Schaffer collateral-CA1 pyramidal cell synapses.

Antinociceptive actions of honokiol and magnolol on glutamatergic and inflammatory pain

open access: yesJournal of Biomedical Science, 2009
The antinociceptive effects of honokiol and magnolol, two major bioactive constituents of the bark of Magnolia officinalis, were investigated on animal paw licking responses and thermal hyperalgesia induced by glutamate receptor agonists including ...

Neurochemical Changes in the Mouse Hippocampus Underlying the Antidepressant Effect of Genetic Deletion of P2X7 Receptors. [PDF]

open access: yes, 2013
Recent investigations have revealed that the genetic deletion of P2X7 receptors (P2rx7) results in an antidepressant phenotype in mice. However, the link between the deficiency of P2rx7 and changes in behavior has not yet been explored.

Extensive neuroadaptive changes in cortical gene-transcript expressions of the glutamate system in response to repeated intermittent MDMA administration in adolescent rats

open access: yesBMC Neuroscience, 2008
Background Many studies have focused on the implication of the serotonin and dopamine systems in neuroadaptive responses to the recreational drug 3,4-methylenedioxy-metamphetamine (MDMA).

The G protein-coupled receptor heterodimer network (GPCR-HetNet) and its hub components [PDF]

open access: yes, 2014
G protein-coupled receptors (GPCRs) oligomerization has emerged as a vital characteristic of receptor structure. Substantial experimental evidence supports the existence of GPCR-GPCR interactions in a coordinated and cooperative manner.

When, where and how? Focus on neuronal calcium dysfunctions in Alzheimer's Disease. [PDF]

open access: yes, 2016
Alzheimer\u2019s disease (AD), since its characterization as a precise form of dementia with its own pathological hallmarks, has captured scientists\u2019 attention because of its complexity.

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...
