Cell‐Type Specific Circuits in the Mammillary Body for Place and Object Recognition Memory
Advanced Science, EarlyView.Li et al. defined two novel glutamatergic neuronal subtypes in the medial mammillary nucleus, pars lateralis‐located parvalbumin (PV) neurons, and basalis‐located Drd2 neurons. PV and Drd2 neurons differ in their electrophysiological properties encoded by Kcnn4 and Cacna1h, and selectively modulate place and object recognition memory by two distinct ...

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

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

Calcineurin Mediates Synaptic Scaling Via Synaptic Trafficking of Ca2+-Permeable AMPA Receptors
PLoS Biology, 2014 Kim and Ziff examine the molecular mechanism of synaptic scaling, showing that inhibition of neuronal excitability reduces calcium influx into neurons, resulting in decreased calcineurin activity.

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

Advanced Science, EarlyView.Graphic illustration showing the strategic approaches based on the currently investigated evidence of psychedelics that suggests the challenges and how to address the prescription of mental disorders. These applicable avenues may provide substantial insight into distinguishing between brain networks and psychedelics.

Pharmacological analysis of ionotropic glutamate receptor function in neuronal circuits of the zebrafish olfactory bulb. [PDF]
PLoS ONE, 2008 Although synaptic functions of ionotropic glutamate receptors in the olfactory bulb have been studied in vitro, their roles in pattern processing in the intact system remain controversial.

Algebraic study of receptor-ligand systems: a dose-response analysis [PDF]
arXiv, 2022 The study of a receptor-ligand system generally relies on the analysis of its dose-response (or concentration-effect) curve, which quantifies the relation between ligand concentration and the biological effect (or cellular response) induced when binding its specific cell surface receptor.

Advanced Science, EarlyView.A new CdCS rat model is developed using CRISPR‐Cas9 technology. It shows impairments in cognitive and social behaviors, neuronal dendrite abnormalities in the hippocampus and mPFC, and inflammatory and immune processes in mPFC brain cells. Early AAV‐Ctnnd2 gene therapy enhances cognitive function in CdCS rats.
