The prion protein regulates glutamate-mediated Ca2+ entry and mitochondrial Ca2+ accumulation in neurons [PDF]
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.

Amyloid-β effects on synapses and memory require AMPA receptor subunit GluA3
Significance In Alzheimer’s disease, soluble clusters of amyloid-β (Aβ) are believed to degrade synapses and impair memory formation. The removal of AMPA receptors from synapses was previously shown to be a critical step in Aβ-driven synapse loss.

Recent Findings on AMPA Receptor Recycling [PDF]
α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPA-Rs) are tetrameric protein complexes that mediate most of the fast-excitatory transmission in response to the neurotransmitter glutamate in neurons. The abundance of AMPA-Rs at the surface of excitatory synapses establishes the strength of the response to glutamate. It is thus evident

Objectives Rheumatoid arthritis (RA) associated anti‐citrullinated protein antibodies (ACPA) target various antigens by binding short citrulline‐amino acid motifs, resulting in heterogeneous ACPA‐profiles among patients. Here we analyzed ACPA‐patterns by recognized citrulline‐motifs in relation to the RA risk factors HLA‐DRB1 shared epitope (SE ...

AMPA, NMDA and GABAA receptor mediated network burst dynamics in cortical cultures in vitro [PDF]
In this work we study the excitatory AMPA, and NMDA, and inhibitory GABAA receptor mediated dynamical changes in neuronal networks of neonatal rat cortex in vitro. Extracellular network-wide activity was recorded with 59 planar electrodes simultaneously under different pharmacological conditions.

Stargazin Dephosphorylation Mediates Homeostatic Synaptic Downscaling of Excitatory Synapses
Synaptic scaling is a form of homeostatic plasticity that is critical for maintaining neuronal activity within a dynamic range, and which alters synaptic strength through changes in postsynaptic AMPA-type glutamate receptors.

Intracellular machinery for the transport of AMPA receptors [PDF]
AMPA‐type glutamate receptors are one of the most dynamic components of excitatory synapses. Their regulated addition and removal from synapses leads to long‐lasting forms of synaptic plasticity, known as long‐term potentiation (LTP) and long‐term depression (LTD).

Role of Glutamate Excitotoxicity in Glioblastoma Growth and Its Implications in Treatment
ABSTRACT Glioblastoma is a highly malignant and invasive type of primary brain tumor that originates from astrocytes. Glutamate, a neurotransmitter in the brain plays a crucial role in excitotoxic cell death. Excessive glutamate triggers a pathological process known as glutamate excitotoxicity, leading to neuronal damage.

Fate of the organophosphate herbicide glyphosate in arable soils and its relationship to soil phosphorus status [PDF]
Glyphosate is one of the world's most widely used herbicides. This study was undertaken to unravel the factors affecting its movement, sorption, persistence and leachability in different Finnish soils to create a sound basis for risk assessment. Field

Seizure control by decanoic acid through direct AMPA receptor inhibition
See Rogawski (doi:10.1093/awv369) for a scientific commentary on this article. The MCT ketogenic diet, an established treatment for drug-resistant epilepsy, leads to an elevation of plasma decanoic acid and ketones. Chang et al. show that decanoic acid,
