OptoMitoTether optogenetically tethers adjacent mitochondria via CRY2PHR oligomerization, reducing nearest-neighbor distances and elevating mitochondrial membrane potential during blue light stress.
- Why it matters: Precise, reversible control of mitochondrial membrane potential is limited, leaving uncertainty about how spatially organized inter-mitochondrial contacts affect bioenergetic resilience under blue light damage.
- What they did: The authors engineered OptoMitoTether to reversibly modulate inter-mitochondrial proximity with high spatiotemporal precision, then measured MMP, ROS, and ATP during prolonged blue light exposure.
- The result: Activation was linked to lower ROS and preserved ATP, maintained mitochondrial bioenergetic function in human retinal cells, and extended lifespan in Caenorhabditis elegans under chronic blue light exposure.
