Summary
Kainate receptors (KARs), a type of ionotropic glutamate receptor, modulate neural circuits. Research has advanced understanding of KARs, their functions, and roles in brain disorders.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- Ionotropic glutamate receptors (iGluRs) are crucial for fast excitatory neurotransmission in the brain.
- Kainate receptors (KARs), an iGluR subfamily, modulate neuronal circuitry at postsynaptic and presynaptic sites.
- KARs are tetrameric receptors composed of subunits from two gene families (GluK1-3 and GluK4-5).
Purpose of the Study:
- To review the current understanding of kainate receptor biology.
- To explore the localization, interactome, physiological functions, and regulation of KARs.
- To discuss KARs in the context of associated neurological disorders.
Main Methods:
- Cloning of KAR subunits (GluK1-5) enabling recombinant expression in heterologous systems.
- Functional studies of subunit combinations and splice variants.
- Structural studies of KAR domains and full-length receptors.
Main Results:
- Recombinant expression facilitated understanding of KAR functional differences, trafficking, and drug discovery.
- Structural studies revealed unique functional mechanisms of KARs.
- Significant progress has been made in understanding KAR localization, interactome, and physiological roles.
Conclusions:
- Kainate receptors play vital roles in modulating neuronal communication.
- Advances in molecular and structural biology have deepened our knowledge of KARs.
- Further research into KARs is essential for understanding and treating associated brain disorders.

2.5K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

01:19The Role of Ion Channels in Neuronal Computation
3.3K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

7.0K
Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

8.5K
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

01:22Opioid Receptors: Overview
1.6K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...
