Lysosomes, the cell's 'recycling centers,' found to help control heart rhythm

Scientists have discovered that lysosomes, structures traditionally viewed as the cell's recycling centers, also play a role in regulating the heart's natural rhythm. Researchers at the University of Liverpool and University of Oxford, working with national and international collaborators, found that lysosomes act as signaling centers in heart cells, helping the heart's natural pacemaker respond when the heart needs to beat faster.
