Description

Rayen De Fazio and five co-authors showed in 2026 that a proton channel known from other cells also works inside heart mitochondria. Mitochondria power the heartbeat, and their output hinges on how protons are moved and stored. The channel, called Hv1, lets protons out under voltage control and steadies cell acidity elsewhere in the body.

Working with mouse heart mitochondria, the team found the channel active there for the first time. Blocking it made the inner space more alkaline and raised the voltage across the membrane, both at work and at rest in whole heart cells. A new lever on heart energy is now in view.
