Glutamatergic Mechanisms in Glioblastoma and Tumor-Associated Epilepsy

open access: yesCells, 2021
The progression of glioblastomas is associated with a variety of neurological impairments, such as tumor-related epileptic seizures. Seizures are not only a common comorbidity of glioblastoma but often an initial clinical symptom of this cancer entity ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]

open access: yes, 2001
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Olig2/Plp-positive progenitor cells give rise to Bergmann glia in the cerebellum. [PDF]

open access: yes, 2013
NG2 (nerve/glial antigen2)-expressing cells represent the largest population of postnatal progenitors in the central nervous system and have been classified as oligodendroglial progenitor cells, but the fate and function of these cells remain ...

mGluR1α expression in the hippocampus, subiculum, entorhinal cortex and superior temporal gyrus in Alzheimer’s disease

open access: yesIBRO Neuroscience Reports, 2022
Glutamate is the main excitatory neurotransmitter in the central nervous system, responsible for a plethora of cellular processes including memory formation and higher cerebral function and has been implicated in various neurological disease states ...

A detailed study of the diastereoselective catalytic hydrogenation of 6-hydroxytetrahydroisoquinoline-(3R)-carboxylic ester intermediates [PDF]

open access: yes, 2012
A key step towards a highly-selective antagonist of ionotropic glutamate receptors entails the diastereoselective arene hydrogenation of an enantiopure tetrahydroisoquinoline.

Tripartite signalling by NMDA receptors

open access: yesMolecular Brain, 2020
N-methyl-d-aspartate receptors (NMDARs) are excitatory glutamatergic receptors that are fundamental for many neuronal processes, including synaptic plasticity.

Ubiquitin-dependent trafficking and turnover of ionotropic glutamate receptors

open access: yesFrontiers in Molecular Neuroscience, 2015
Changes in synaptic strength underlie the basis of learning and memory and are controlled, in part, by the insertion or removal of AMPA-type glutamate receptors at the postsynaptic membrane of excitatory synapses.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

open access: yesAdvanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Negative modulation of the GABAAρ1 receptor function by l-cysteine [PDF]

open access: yes, 2017
l-Cysteine is an endogenous sulfur-containing amino acid with multiple and varied roles in the central nervous system, including neuroprotection and the maintenance of the redox balance.

Ionotropic Glutamate Receptors & CNS Disorders [PDF]

open access: yesCNS & Neurological Disorders - Drug Targets, 2008
Disorders of the central nervous system (CNS) are complex disease states that represent a major challenge for modern medicine. Although aetilogy is often unknown, it is established that multiple factors such as defects in genetics and/or epigenetics, the environment as well as imbalance in neurotransmitter receptor systems are all at play in ...
