Louis J IgnarroLouis J. Ignarro, PhD, is Distinguished Professor Emeritus of the Department of Molecular and Medical Pharmacology at the UCLA School of Medicine. He has broad and extensive experience in the molecular and chemical biology of the nitric oxide-cyclic MP signaling systems. He and his basic research teams have discovered and expanded the production and actions of nitric oxide in mammalian tissues, including the protective roles of nitric oxide in preventing hypertension, stroke and myocardial infarction, and its neurotransmitter role as the mediator of erectile function in humans. For these discoveries, he was awarded the Nobel Prize in Physiology or Medicine. Read More Read Less
