Clathrin-Independent Trafficking of AMPA Receptors [PDF]
The Journal of Neuroscience, 2015 Membrane trafficking of AMPA receptors (AMPARs) is critical for neuronal function and plasticity. Although rapid forms of AMPAR internalization during long-term depression (LTD) require clathrin and dynamin, the mechanisms governing constitutive AMPAR turnover and internalization of AMPARs during slow homeostatic forms of synaptic plasticity remain ...

Advanced Science, EarlyView.This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

AMPA receptor subunit expression in the endoplasmic reticulum in frontal cortex of elderly patients with schizophrenia. [PDF]
PLoS ONE, 2012 Several lines of evidence indicate altered trafficking of α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptors in schizophrenia. Previous reports have shown potential changes in the trafficking of AMPA receptors based on subunit expression

Mechanisms of AMPA Receptor Endosomal Sorting [PDF]
Frontiers in Molecular Neuroscience, 2018 The regulation of synaptic AMPA receptors (AMPARs) is critical for excitatory synaptic transmission, synaptic plasticity and the consequent formation of neural circuits during brain development and their modification during learning and memory processes.

Advanced Science, EarlyView.Depression, a prevalent neuropsychiatric disorder with unclear pathogenesis, involves dysfunctional adenylyl cyclase 8 (Adcy8) as a key risk factor. Chronic stress selectively reduces Adcy8 expression in the dorsal CA1 (dCA1) neurons. Depletion of Adcy8 in dCA1 excitatory neurons induces depressive‐like behaviors by impairing neuronal excitability and ...

Characterization of Phosphorylation Sites on the Glutamate Receptor 4 Subunit of the AMPA Receptors [PDF]
, 1999 Recent studies have suggested that protein phosphorylation of glutamate receptors may play an important role in synaptic transmission. Specifically, the phosphorylation of AMPA receptors has been implicated in cellular models of synaptic plasticity.

Recent Findings on AMPA Receptor Recycling [PDF]
Frontiers in Cellular Neuroscience, 2018 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

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning
Advanced Science, EarlyView.Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Acute inactivation of PSD-95 destabilizes AMPA receptors at hippocampal synapses. [PDF]
PLoS ONE, 2013 Postsynatptic density protein (PSD-95) is a 95 kDa scaffolding protein that assembles signaling complexes at synapses. Over-expression of PSD-95 in primary hippocampal neurons selectively increases synaptic localization of AMPA receptors; however, mice ...

Heroin-piracetam mixture: suggested mechanisms of action and risks of misinterpretation for drug users [PDF]
, 2017 Piracetam is a positive allosteric modulator of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor that has been frequently used in the treatment of cognitive disorders.
