Investigators from the Smidt Heart Institute at Cedars-Sinai have identified how biological pacemaker cells—cells that control your heartbeat—can “fight back” against therapies to biologically correct abnormal heartbeat rates. The research also uncovered a new way to boost the effectiveness of RNA therapies by controlling this “fighting back” activity.
This novel concept, published today in the peer-reviewed journal Cell Reports Medicine, is an important step in the evolution and creation of biological pacemakers—which aim to one day replace traditional, electronic pacemakers.
“We are all born with a specialized group of heart cells that set the pace for our heartbeats,” said Eugenio Cingolani, MD, senior author of the study and director of the Cardiogenetics Program in the Smidt Heart Institute at Cedars-Sinai. “But in some people, this natural heartbeat is too slow, leading to the need for an electronic pacemaker.”
