Foreign Media: A team from the School of Medicine at Zhejiang University has developed a novel therapy that implants plant photosynthetic systems into animal cells: they extracted thylakoid structures from plant chloroplasts, fabricated them into nanoparticles coated with cell membrane layers, enabling cross-species targeted delivery.
Experiments showed that light-activated nanoparticles can restore stable interactions between mitochondria and the endoplasmic reticulum, improving cellular energy metabolism. In rat models of intervertebral disc degeneration, the therapy effectively alleviated degenerative symptoms; for larger animals like rabbits, the team also designed implantable LEDs capable of wireless charging, allowing deep-tissue treatment to be controlled remotely via smartphone.
The study was published in Nature Communications, offering a new approach to treating aging and related degenerative diseases by regulating organelle interaction networks.
