Abstract:
The state-of-the-art in investigations of the mu-opioid receptors (ORs) is reviewed. Published information on the interaction between mu-ORs and various G-proteins is summarized and data on the neutral antagonists and inverse agonists of mu-opioid receptor are generalized. The notions about the spontaneous activation of mu-ORs are considered and numerous reports on the interaction between mu-ORs and GIRK, KATP, and Kv channels are analyzed. The role of L, N, and P/Q types of Ca(2+)-channels in mu-OR-mediated intracellular signaling is discussed.

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 include the...

Non-gated Ion Channels
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism.
