Work

Communication between the cells in your body are managed by substances called hormones. Each cell has a small receiver known as a receptor, which is able to receive hormones. In order to track these receptors, in 1968 Robert Lefkowitz attached a radioactive isotope of iodine to the hormone adrenaline. By tracking the radiation emitted by the isotope, he succeeded in finding a receptor for adrenaline and studied how it functions. It was later discovered that there is an entire family of receptors that look and act in similar ways - "G-protein-coupled receptors". Approximately half of all medications used today make use of this kind of receptor.
