The Role of IgM Anti‐acetylated Protein Antibodies and B Cells in the Origin of Antimodified Protein Autoimmunity in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated protein antibodies (ACPA), anti‐carbamylated protein antibodies (anti‐CarP), and anti‐acetylated protein antibodies (AAPA). In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role ...

Ethanol increases desensitization of recombinant GluR-D AMPA receptor and TARP combinations

, 2009
Glutamate receptors are important target molecules of the acute effect of ethanol. We studied ethanol sensitivity of homomeric GluR-D receptors expressed in human embryonic kidney 293 cells and examined whether recently discovered transmembrane α-amino-3-

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

Cytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Cortical neurones with Ca2+permeable AMPA/kainate channels display distinct receptor immunoreactivity and are GABAergic

Neurobiology of Disease, 1994
A minority subset of cortical neurones exhibit kainate-activated Co2+uptake, a marker for AMPA/kainate receptor gated Ca2+-permeable channels. Consistent with enhanced Ca2+influx through these channels, Co2+-positive neurones are unusually vulnerable to ...

KIF1A‐Mediated Axonal Transport of Netrin‐1 in iPSC‐Derived Human Forebrain Neurons

Cytoskeleton, EarlyView.
ABSTRACT Netrin‐1 is a secreted laminin‐like protein that functions as a guidance cue for axon pathfinding in development. Netrin‐1 also modulates synapse formation in developing neurons and long‐term potentiation in mature neurons. Netrin‐1 is expressed in human neurons; however, its intracellular distribution and trafficking have not been assessed ...

IL1RAPL1 associated with mental retardation and autism regulates the formation and stabilization of glutamatergic synapses of cortical neurons through RhoA signaling pathway. [PDF]

PLoS ONE, 2013
Interleukin-1 receptor accessory protein-like 1 (IL1RAPL1) is associated with X-linked mental retardation and autism spectrum disorder. We found that IL1RAPL1 regulates synapse formation of cortical neurons.

GRIA2 Variant Associated With Paradoxical Response to Perampanel Expanding the Spectrum of GRIA2‐Related Epileptic Encephalopathy: Case Report and Literature Review

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Introduction GRIA2 encodes the GluA2 ionotropic α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid (AMPA) receptor subunit. Pathogenic GRIA2 variants cause epilepsy, developmental delay, and neurobehavioral disorders. Characterizations of clinical features, including seizure types and their treatments, in patients with GRIA2‐related ...

Regulating AMPA Receptors with Isoxazole-4-Carboxamide Derivatives: An Electrophysiological Study

Journal of Xenobiotics
Isoxazole carboxamide derivatives are intriguing modulators of ionotropic glutamate receptors; more specifically, their prospective analgesic activities based on non-opioid pathways have sparked widespread research.

Ionotropic Glutamate Receptors in Epilepsy: A Review Focusing on AMPA and NMDA Receptors

Biomolecules, 2020
It is widely accepted that glutamate-mediated neuronal hyperexcitation plays a causative role in eliciting seizures. Among glutamate receptors, the roles of N-methyl-D-aspartate (NMDA) and α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA ...

Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor channels lacking the N-terminal domain.

, 2002
Ionotropic glutamate receptor (iGluR) subunits contain a ∼400-residue extracellular N-terminal domain (“X domain”), which is sequence-related to bacterial amino acid-binding proteins and to class C G-protein-coupled receptors.
