Marco Orecchione: The Smell of Heart Disease

What we eat not only feeds us, but also the bacteria that call our intestines home. When we consume an unbalanced diet high in fat and cholesterol these bacteria produce smelly substances that appear to promote the build-up of atherosclerotic plaques. Dr. Orecchioni believes he found the missing link: immune cells isolated from plaques that can sense these odorants and respond with pro-inflammatory and pro-atherosclerotic signals.
