Ligand-gated ion channels (LGICs) form a diverse superfamily of cell-surface neurotransmitter receptors that mediate rapid cell–cell signalling. They are multisubunit transmembrane proteins in which 3–5 subunits are arranged around a central ion channel pore. In addition to their role as receptors for neurotransmitters, LGICs have been implicated in several neurological disorders and are important target sites for drug therapy and drug development.
