Synaptic plasticity of ionotropic glutamate receptors has been extensively studied with a particular focus on the role played by NMDA (N-methyl-D-aspartate) receptors in the induction of synaptic plasticity and the subsequent movement of AMPA (alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid) receptors. The third subtype of ionotropic glutamate receptor, kainate receptors, has not been studied to the same extent, but recent evidence shows that these receptors also exhibit synaptic… 
Modulation of excitatory neurotransmission by neuronal/glial signalling molecules: interplay between purinergic and glutamatergic systems
TLDR
The purinergic system is a promising possibility to optimize the activity of the glutamatergic system by exerting not only direct and indirect influences on NMDA receptors but, by modulating glutamatorgic transmission, also plays an important role in glia-neuron communication.
Discovery of a new class of ionotropic glutamate receptor antagonists by the rational design of (2S,3R)-3-(3-carboxyphenyl)-pyrrolidine-2-carboxylic acid.
TLDR
The discovery of (2S,3R)-3-(3- carboxyphenyl)-pyrrolidine-2-carboxylic acid (1) is presented based on a rational design process and Binding affinities of 1 at native ionotropic Glu receptors were determined to be in the micromolar range.
Kainate-type glutamate receptors modulating network activity in developing hippocampus
TLDR
This work has shown that activation of high-affinity kainate receptors promotes network burst generation via enhancing spontaneous spiking of immature CA3 pyramidal neurons and suppresses network effect of ethanol in a developmental manner via metabotropically controlling afterhyperpolarization in immature interneurons.
Channel-opening kinetic mechanism of wild-type GluK1 kainate receptors and a C-terminal mutant.
TLDR
The results indicate that the amino acid sequence near or within the C-terminal ER retention signal sequence, which affects receptor trafficking and/or expression, does not affect channel gating properties.
Human GluR6c, a functional splicing variants of GluR6, is mainly expressed in non-nervous cells
Channel-opening kinetic mechanism for human wild-type GluK2 and the M867I mutant kainate receptor.
TLDR
The results suggest that the human GluK2 is relatively a slowly activating channel but more sensitive to glutamate, as compared to the rat ortholog, despite the fact that thehuman and rat forms share 99% sequence homology.
Structure-Activity Relationship Study of Ionotropic Glutamate Receptor Antagonist (2S,3R)-3-(3-Carboxyphenyl)pyrrolidine-2-carboxylic Acid.
Herein we describe the first structure-activity relationship study of the broad-range iGluR antagonist (2S,3R)-3-(3-carboxyphenyl)pyrrolidine-2-carboxylic acid (1) by exploring the pharmacological
Pain pharmacology and analgesia
TLDR
In the next decade, a new generation of pain medicines is likely to reach the market, thereby expanding the armamentarium of drugs available to clinicians for the management of persistent on-going pain.
Rational Design, Synthesis and Pharmacological Evaluation of the (2R)‐ and (2S)‐Stereoisomers of 3‐(2‐Carboxypyrrolidinyl)‐2‐methyl Acetic Acid as Ligands for the Ionotropic Glutamate Receptors
TLDR
The rational design, synthesis and pharmacological evaluation of two new stereoisomeric (S)‐glutamate (Glu) analogues revealed that one stereoisomers showed a subtype selectivity profile with low micromolar affinity for GLUK1 and GluK3 and a 10‐ to 15‐fold lower affinity forGluK2.

The synaptic activation of kainate receptors
TLDR
It is demonstrated that high-frequency stimulation of mossy fibres in rat hippocampal slices, in the presence of the highly selective AMPA receptor antagonist GYKI 53655, plus NMDA- and GABA-receptor antagonists, activates an inward current in CA3 neurons that has a pharmacology typical of kainate receptors.
Developmental and activity- dependent regulation of kainate receptors at thalamocortical synapses
TLDR
It is shown that developing thalamocortical synapses express postsynaptic kainate receptors as well as AMPA receptors; however, the two receptor subtypes do not co-localize.
Regulation of kainate receptors by protein kinase C and metabotropic glutamate receptors
TLDR
It is demonstrated for the first time that kainate receptor function can be modulated by activation of metabotropic glutamate receptors and have implications for understanding mechanisms of synaptic transmission, plasticity and disorders such as epilepsy.
Kainate receptors mediate a slow postsynaptic current in hippocampal CA3 neurons
TLDR
It is reported that repetitive activation of the hippocampal mossy fibre pathway, which is associated with high-affinity kainate binding and many of the kainATE receptor subtypes, generates a slow excitatory synaptic current with all of the properties expected of a kainates receptor.
Molecular physiology of kainate receptors.
TLDR
Although significant progress has been made toward the elucidation of their importance for brain function, kainate receptors remain largely an enigma and some new roads that should be explored to obtain a deeper understanding of this young, but intriguing, class of proteins are proposed.

TLDR
A comparison of the distribution of mRNAs encoding five glutamate receptor subunits exhibiting high-affinity kainate sites indicates that a complex mosaic of receptor variants underlies the high-Affinity kainsate receptor in the vertebrate brain.
Distinct Subunits in Heteromeric Kainate Receptors Mediate Ionotropic and Metabotropic Function at Hippocampal Mossy Fiber Synapses
TLDR
A model in which KARs could operate in two modes at mossy fiber synapses is proposed: through a direct ionotropic action of GluR6, and through an indirect G-protein-coupled mechanism requiring the binding of glutamate to KA2.
