Images of crucial cell receptors show promising new drug targets

Almost 35% of drugs approved by the Food and Drug Administration work by targeting G protein-coupled receptors (GPCRs), proteins embedded in cell membranes that allow cells to communicate with each other. Adhesion G protein-coupled receptors (aGPCRs) are the second largest family of these receptors in humans. As their name suggests, they help cells adhere (stick to each other), and send signals inside the body.
