Voltage-Gated Ion Channels
Ligand-Gated Ion Channels
- LGIC are targets for many drugs, such as anesthetics, antipsychotics, and antidepressants. They are named according to the ligand to which they respond and are divided into three families based upon molecular biology and protein structure criteria.
“Cys-Loop” LGIC
- They constitute the largest class of LGICs and include nicotinic acetylcholine receptors (nAChR), γ-aminobutyric acid (GABA) receptors, 5-hydroxytryptamine-3 (5HT3) receptors, and glycinereceptors. The nAChR and 5-HT3R are excitatory receptors, while the GABA receptors and glycine receptors are inhibitory in nature. The nAChRs are activated endogenously by the neurotr…
Ionotropic Glutamate Receptors
