Pituitary Adenylate-Cyclase Activating Polypeptide Regulates Hunger- and Palatability-Induced Binge Eating [PDF]

, 2016
While pituitary adenylate cyclase activating polypeptide (PACAP) signaling in the hypothalamic ventromedial nuclei (VMN) has been shown to regulate feeding, a challenge in unmasking a role for this peptide in obesity is that excess feeding can involve ...

Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...

A Scoping Review of Corticosterone-Induced Changes in Ionotropic Glutamate Receptor Levels and Localization in the Rodent Brain: Implications for the Auditory System

Brain Sciences
Background: The ionotropic glutamate receptor AMPA (AMPAR) mediates fast excitatory synaptic transmission and regulates synaptic strength in various parts of the CNS.

Postsynaptic protein organization revealed by electron microscopy. [PDF]

, 2019
Neuronal synapses are key devices for transmitting and processing information in the nervous system. Synaptic plasticity, generally regarded as the cellular basis of learning and memory, involves changes of subcellular structures that take place at the ...

Pharmacological manipulation of the immediate effects of spinal trauma in neonatal rats reveals a crucial role for TRPV4 receptors

The Journal of Physiology, EarlyView.
Abstract figure legend A, schematic illustration of the ventral aspect of an ex vivo preparation of the entire CNS from a neonatal rat subjected to a calibrated thoracic impact. The trauma induced a large depolarising injury potential (DIP, black trace) recorded from the L5 ventral root (VRrL5), which was markedly reduced by transient receptor ...

Astrocytes as central integrators of neural circuit function: Mechanisms and dysregulation in neuropsychiatric disorders

Clinical and Translational Discovery, Volume 6, Issue 2, April 2026.
1. Astrocytes are central integrators of neural circuit function through tripartite synapse modulation and neurovascular coupling. 2. Dysregulation of glutamate/GABA homeostasis and neuroinflammation represents shared mechanisms across diverse neuropsychiatric disorders. 3.

VGLUT1 and PSD‐95 Expression Remains Stable in the Prefrontal and Cerebellar Cortices of the VPA Autism Rat Model

Developmental Neurobiology, Volume 86, Issue 2, April 2026.
ABSTRACT Autism spectrum disorder (ASD) has recently been described as a synaptopathy where dysregulation at the level of the synapse is thought to evoke an excitation–inhibition (E/I) imbalance implicated in its pathogenesis. The mechanisms through which alterations in glutamatergic signaling bring about an E/I imbalance remain elusive.

ADAR-mediated RNA editing suppresses sleep by acting as a brake on glutamatergic synaptic plasticity. [PDF]

, 2016
It has been postulated that synaptic potentiation during waking is offset by a homoeostatic reduction in net synaptic strength during sleep. However, molecular mechanisms to support such a process are lacking. Here we demonstrate that deficiencies in the
