Cedars-Sinai Heart Institute researchers have found that six proteins -- five more than previously thought -- are responsible for cell-to-cell communication that regulates the heart and plays a role in limiting the size of heart attacks and strokes. The smallest of these proteins directs the largest in performing its role of coordinating billions of heart cells during each heartbeat. Together, the proteins synchronize the beating heart, the researchers determined.
