Light to the heart to restore healthy beats

Facebook X LinkedIn Email
When a person’s heart slows or stops, the current practice is to jump-start it with a blast of electricity from a pacemaker or defibrillator. But a multiuniversity team aims to put an optogenetic twist on the procedure by replacing the violent jolt of electricity with gently applied light. “Applying electricity to the heart has its drawbacks,” said Natalia Trayanova, a professor at Johns Hopkins University and team leader of a group of biomedical engineers from Johns Hopkins and Stony Brook University. “When we use a defibrillator, it’s like blasting open a...Read full article

    optogenetics
    A discipline that combines optics and genetics to enable the use of light to stimulate and control cells in living tissue, typically neurons, which have been genetically modified to respond to light. Only the cells that have been modified to include light-sensitive proteins will be under control of the light. The ability to selectively target cells gives researchers precise control. Using light to control the excitation, inhibition and signaling pathways of specific cells or groups of...
