JEAN-PIERRE CHANGEUX has been director of the molecular neurobiology unit of the Pasteur Institute in Paris since 1972. He is also a professor at the institute and at the College of France. Changeux has won many awards for his contributions to neuroscience.ACETYLCHOLINE RECEPTOR, which consists of five subunits (left), was the first neurotransmitter receptor to be isolated. Later work showed it to include not only neurotransmitter binding sites but also an ion-transporting channel (right).(The beta and delta subunits and part of one alpha subunit have been cut away for clarity.) The channel is closed when the receptor is at rest, but it opens rapidly when the two alpha subunits both combine with acetylcholine.
