Metabotropic glutamate receptors in auditory processing [PDF]

Neuroscience, 2014
As the major excitatory neurotransmitter used in the vertebrate brain, glutamate activates ionotropic and metabotropic glutamate receptors (mGluRs), which mediate fast and slow neuronal actions, respectively. Important modulatory roles of mGluRs have been shown in many brain areas, and drugs targeting mGluRs have been developed for the treatment of ...

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Non‐ionotropic NMDAR signalling activates Panx1 to induce P2X4R‐dependent long‐term depression in the hippocampus

The Journal of Physiology, EarlyView.
Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]

, 2013
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

Adaptations to hypoxia in the vertebrate retina

The Journal of Physiology, EarlyView.
Abstract figure legend Most animals, including mammals, are susceptible to the damaging effects of hypoxia or ischaemia, where the result is neuronal cell death in the brain. By contrast, some neurons of the mammalian retina are less sensitive to hypoxia. In both brain and retina, neurons may survive if first preconditioned with ischaemia.

The mysterious middlemen making your vision pop: understanding the function of amacrine cells

The Journal of Physiology, EarlyView.
Abstract figure legend This review aims to illustrate the diversity and function of amacrine cells in the retina. The diversity of amacrine cell subtypes is depicted based on morphology, stratification and neurotransmitter expression, along with their synaptic connectivity with bipolar and ganglion cells, emphasizing inhibitory and modulatory roles ...

Pituitary Adenylate Cyclase-Activating Polypeptide Orchestrates Neuronal Regulation Of The Astrocytic Glutamate-Releasing Mechanism System x\u3csub\u3ec\u3c/sub\u3e\u3csup\u3e−\u3c/sup\u3e [PDF]

, 2016
Glutamate signaling is achieved by an elaborate network involving neurons and astrocytes. Hence, it is critical to better understand how neurons and astrocytes interact to coordinate the cellular regulation of glutamate signaling.

Beyond the tumor: Enhancing pancreatic cancer therapy through glutamine metabolism and innovative drug delivery

Journal of Cell Communication and Signaling, Volume 19, Issue 3, September 2025.
The top row shows key drivers‐KRAS, c‐Myc and HIF‐1a‐alongside gut and tumor microbiota, all converging on glutamine metabolism in PDAC. At the center, glutamine handling is depicted as the linchpin of tumor growth, biosynthesis and immune modulation. The green panel lists major intervention strategies: DON‐loaded nanoparticles, prodrugs (DRP‐104/JHU ...
