Summary
Glycine transporters (GLYT1 and GLYT2) regulate neurotransmission. Understanding their mechanisms and developing specific inhibitors may lead to new treatments for CNS disorders.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- Glycine acts as an inhibitory neurotransmitter in the central nervous system (CNS).
- Glycine also functions as a co-agonist for NMDA glutamate receptors, contributing to excitatory neurotransmission.
- Synaptic glycine concentrations are primarily regulated by GLYT1 and GLYT2 transporters, which have distinct distributions and functions.
Purpose of the Study:
- To review recent advancements in understanding the physiological roles of glycine transporters (GLYT1 and GLYT2).
- To explore how structural and genetic studies illuminate glycine transport mechanisms.
- To discuss the therapeutic potential of targeting glycine transporters.
Main Methods:
- Development and application of specific GLYT1 and GLYT2 inhibitors.
- Generation and analysis of gene-deficient mice models.
- Determination of the three-dimensional structure of a bacterial glycine transporter homologue.
Main Results:
- Recent studies using specific inhibitors and genetic models have advanced the understanding of glycine transporter functions.
- Structural insights into a bacterial homologue provide mechanistic details of glycine transport.
- Complementary distribution and activity of GLYT1 and GLYT2 are crucial for regulating glycine levels.
Conclusions:
- Knowledge of glycine transporters' structure and function is rapidly expanding.
- Targeting glycine transporters holds promise for developing novel therapeutics.
- Potential applications include treatments for antipsychotic, procognitive, and analgesic purposes.

01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
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...
01:26Neurochemical Transmission: Sites of Drug Action
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...
01:26Chemical Synapses
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

01:29Excitatory and Inhibitory Effects of Neurotransmitters
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...
