Researchers 'see' structure of open nicotinic acetylcholine ion channels

The neurotransmitter acetylcholine is an essential chemical communicator, carrying impulses from neurons to skeletal muscle cells and many parts of the nervous system. Now researchers at the University of Illinois have painstakingly mapped the interior of a key component of the relay system that allows acetylcholine to get its message across. Their findings, which appear in the current issue of Nature Structure & Molecular Biology, reveal how the muscle nicotinic acetylcholine receptor responds to a burst of acetylcholine on the surface of a cell.
