Prize share: 1/1
Signals between different parts of the body are conveyed by small electrical impulses and by chemical substances, hormones and signal substances. Communication also takes place between different cell parts. Earl Sutherland investigated how hormones, especially adrenaline, work. He showed how signals from one cell to another are conveyed by a messenger - the hormone - and how signals within the cell are then conveyed by another messenger. Around 1960 he showed how cyclic adenosine monophosphate (cAMP) serves as the secondary messenger within the cell.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
