Galanin receptor 1 deletion exacerbates hippocampal neuronal loss after systemic kainate administration in mice. [PDF]
Galanin is a neuropeptide with a wide distribution in the central and peripheral nervous systems and whose physiological effects are mediated through three G protein-coupled receptor subtypes, GalR1, GalR2, and GalR3.

The blockade of kainate receptors, in particular with non-competitive antagonists, has—due to their anticonvulsant and neuroprotective properties—therapeutic potential in many central nervous system (CNS) diseases.

Kainate receptor trafficking [PDF]
AbstractKainate receptors (KARs) are ligand‐gated ion channels that can regulate neuronal network activity and are involved in processes ranging from neuronal development and differentiation to neurodegeneration and neuronal cell death. They are tetrameric assemblies which can comprise different subunit combinations and are differentially targeted to ...

A minority subset of cortical neurones exhibit kainate-activated Co2+uptake, a marker for AMPA/kainate receptor gated Ca2+-permeable channels. Consistent with enhanced Ca2+influx through these channels, Co2+-positive neurones are unusually vulnerable to ...

Clathrin-independent but dynamin-dependent mechanisms mediate Ca2+-triggered endocytosis of the glutamate GluK2 receptor upon excitotoxicity [PDF]
We first explore the features of GluK2 endocytosis during kainate excitotoxicity and then explore the role of Ca2+ in the regulation of GluK2 endocytosis. The roles of Ca2+ were examined by treating cells with Ca2+ inhibitors or chelators.

Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]
Adaptive forms of synaptic plasticity that reduce excitatory synaptic transmission in response to prolonged increases in neuronal activity may prevent runaway positive feedback in neuronal circuits.

AMPA Receptor-Mediated Ca2+ Transients in Mouse Olfactory Ensheathing Cells
Ca2+ signaling in glial cells is primarily triggered by metabotropic pathways and the subsequent Ca2+ release from internal Ca2+ stores. However, there is upcoming evidence that various ion channels might also initiate Ca2+ rises in glial cells by Ca2 ...

A role for fast rhythmic bursting neurons in cortical gamma oscillations in vitro [PDF]
Basic cellular and network mechanisms underlying gamma frequency oscillations (30–80 Hz) have been well characterized in the hippocampus and associated structures.

Kainate receptor modulation by NETO2
Glutamate-gated kainate receptors (KARs) are ubiquitous in the central nervous system of vertebrates, mediate synaptic transmission on post-synapse, and modulate transmitter release on pre-synapse. In the brain, the trafficking, gating kinetics, and pharmacology of KARs are tightly regulated by Neuropilin and tolloid-like proteins (Netos).
