Dr. Louis Ignarro Nobel Prize Facts

"Only in America could the son of an uneducated carpenter receive the Nobel Prize in Medicine"

- Dr. Louis Ignarro

Dr. Louis Ignarro

A once relentless 8-year son of immigrants pleaded for his first chemistry set. Dr. Louis Ignarro has since created a Nobel Prize legacy in cardiovascular research with his discovery and subsequent work on nitric oxide. 

Many studies now confirm the cardiovascular benefits of the important molecule nitric oxide

To honor Dr. Louis Ignarro and the world of research he’s inspired on nitric oxide, we’re highlighting the facts about his work and contributions. 

 

Nobel Price in Physiology or Medicine

In 1998, Louis Ignarro, Robert F. Furchgott, and Ferid Murad won the Nobel Prize in medicine. Their research showed how nitric oxide supports cardiovascular health. While folks across the globe may disagree with the “only in America” statement, the outcome of this research displayed how three pharmacologists from diverse backgrounds can come together with one common goal to improve global health. 

In his work, Ignarro discovered that nitric oxide is produced in blood vessels and signals vessels to expand and contract, thus controlling blood flow. In addition to this, he also discovered that nitric oxide is a neurotransmitting gas.

Since these cardiovascular discoveries, many more links to nitric oxide have been made. For example, how nitric oxide assists in brain function, fights infection as an antibacterial and anti-microbial, decreases muscle soreness, assists in metabolic processes, increases exercise performance, and so much more.

1998 Robert F. Furchgott and Ferid Murad were awarded jointly for their discovery of the nitric oxide molecule in the cardiovascular system.

The Nitric Oxide Society

Dr. Ignarro is the founder of the Nitric Oxide Society on a mission to increase research, publishing, education on the role of nitric oxide in health. 

The Nitric Oxide Society was founded in 1996 and is concerned with disseminating important research to the general public about nitric oxide. The Society’s goal is to develop education and training to studies in the research field of nitric oxide and assist in publishing scientific articles that proliferate the topic.
