Modulating Excitatory Synaptic Neurotransmission: Potential Treatment for Neurological Disease?

Neurobiology of Disease, 1998
Excitatory neurotransmission at many CNS synapses depends upon AMPA-type glutamate receptors. Derangements in AMPA receptor-mediated synaptic transmission may be a contributing factor in neurological and neurodegenerative diseases and could be a target ...

PKA drives an increase in AMPA receptor unitary conductance during LTP in the hippocampus

Nature Communications, 2021
Long-term potentiation at hippocampal CA1 synapses can be due to increasing the number and/or single-channel conductance of AMPA receptors. The authors show that PKA and CaMKII are necessary and together sufficient to increase single channel conductance,

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, EarlyView.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

Advanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...

Single-Particle Tracking of AMPA Receptor-Containing Vesicles

Bio-Protocol
AMPA-type receptors are transported large distances to support synaptic plasticity at distal dendritic locations. Studying the motion of AMPA receptor+ vesicles can improve our understanding of the mechanisms that underlie learning and memory ...

Regulation of AMPA receptors in spinal nociception

Molecular Pain, 2010
The functional properties of α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptors in different brain regions, such as hippocampus and cerebellum, have been well studied in vitro and in vivo. The AMPA receptors present a unique characteristic

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 ...

Anti‐carbamylated fibrinogen autoantibodies of IgG and IgA isotypes contribute to a better prognostic stratification in very early rheumatoid arthritis: data from the French national ESPOIR cohort

Arthritis &Rheumatology, Accepted Article.
Objective To investigate the prevalence and longitudinal evolution of anti‐carbamylated fibrinogen antibodies (ACa‐Fib) of IgG and IgA isotypes in early rheumatoid arthritis (RA), and determine whether these antibodies provide additional diagnostic and prognostic information beyond anti‐cyclic citrullinated peptide antibodies (anti‐CCP) and rheumatoid ...

Assembly and Stoichiometry of the AMPA Receptor and Transmembrane AMPA Receptor Regulatory Protein Complex [PDF]

The Journal of Neuroscience, 2010
Glutamate is a major excitatory neurotransmitter in the vertebrate brain. AMPA-type glutamate receptors mediate fast excitatory transmission. AMPA receptors assemble with transmembrane AMPA receptor regulatory protein (TARP) auxiliary subunits and function as native ion channels.

Sustained pharmacodynamic effects of S‐ketamine on cortical excitability and resting‐state brain activity: A randomized, placebo‐controlled trial

British Journal of Clinical Pharmacology, EarlyView.
Aims This study aimed to investigate a set of pharmacodynamic biomarkers reflecting acute, delayed and sustained central nervous system effects of S‐ketamine, used as a tool compound for rapid‐acting antidepressant activity, with the goal of informing biomarker strategies for delayed antidepressant effects.
