How do genetic differences influence heart rate? Decoding the neuro-cardiac dialogue.
Abnormal heart rate increases the risk of cardiovascular disease and death. Hundreds of DNA regions have been linked to heart rate, but their biological functions remain undiscovered. Scientists at the Amsterdam UMC will use innovative human stem cell-derived systems. By combining heart pacemaker cells (which generate the heartbeat) and autonomic nerve cells (which speed up or slow down the rhythm), the team aims to identify processes that influence the electrical activity of heart cells. This research will improve understanding of how genetics determine heart function, contributing to the development of effective treatments for heart rhythm disorders.
