Impaired AMPA signaling and cytoskeletal alterations induce early synaptic dysfunction in a mouse model of Alzheimer's disease

Aging Cell, 2018
Alzheimer's disease (AD) is a devastating neurodegenerative disorder that impairs memory and causes cognitive and psychiatric deficits. New evidences indicate that AD is conceptualized as a disease of synaptic failure, although the molecular and cellular

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.

S‐ketamine Alleviates Neuroinflammation and Attenuates Lipopolysaccharide‐Induced Depression Via Targeting SIRT2

Advanced Science, EarlyView.
S‐ketamine binds directly to SIRT2, facilitating its interaction with NF‐κB p65. This interaction reduces the acetylation of NF‐κB p65 and inhibits its activation, thereby exerting anti‐inflammatory and antidepressant effects. Created by BioRender.

Coupled feedback loops maintain synaptic long-term potentiation: A computational model of PKMzeta synthesis and AMPA receptor trafficking [PDF]

, 2017
In long-term potentiation (LTP), one of the most studied types of neural plasticity, synaptic strength is persistently increased in response to stimulation. Although a number of different proteins have been implicated in the sub-cellular molecular processes underlying induction and maintenance of LTP, the precise mechanisms remain unknown. A particular

Stress-induced changes in social dominance are scaled by AMPA-type glutamate receptor phosphorylation in the medial prefrontal cortex

Scientific Reports, 2018
The establishment and maintenance of social dominance are critical for social stability and the survival and health of individual animals. Stress lead to depression and a decrease in the social status of depressed persons is a risk factor for suicide ...

Superactivation of AMPA receptors by auxiliary proteins [PDF]

Nature Communications, 2016
AbstractGlutamate receptors form complexes in the brain with auxiliary proteins, which control their activity during fast synaptic transmission through a seemingly bewildering array of effects. Here we devise a way to isolate the activation of complexes using polyamines, which enables us to show that transmembrane AMPA receptor regulatory proteins ...

Targeting signaling pathways in neurodegenerative diseases: Quercetin's cellular and molecular mechanisms for neuroprotection

Animal Models and Experimental Medicine, EarlyView.
Quercetin regulates signaling pathways in neurodegenerative diseases, including NF‐κB, sirtuins, and PI3K/Akt. Studies show quercetin improves symptoms and pathology in neurodegenerative models. The study aims to incorporate laboratory research into practical medical treatment, focusing on quercetin's neuroprotective effects and optimal dosage ...

Exploiting the molecular diversity of the synapse to investigate neuronal communication: A guide through the current toolkit

European Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022
Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

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

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
