How the microprotein BRICK1 repairs and protects the heart after a heart attack
Every year, more than 200,000 people in Germany suffer a heart attack. This is caused by blocked coronary arteries. As a result, part of the heart muscle is no longer supplied with sufficient blood and oxygen; the tissue ...
