Des gouttes ophtalmiques activées par la lumière restaurent la vision chez des souris aveugles

63 sources
  • Des chercheurs de l'IBEC ont publié mercredi une étude montrant que des médicaments photosensibles appelés prosthe6 ont restauré une vision fonctionnelle chez des souris et des poissons-zèbres aveugles.
  • Les composés changent de forme lorsqu'ils sont exposés à la lumière, activant les circuits rétiniens survivants pour envoyer des signaux visuels au cerveau, quelle que soit la cause génétique de la cécité.
  • Contrairement à la thérapie génique ou aux implants chirurgicaux, les médicaments ont fonctionné sous forme de gouttes ophtalmiques non invasives, et l'équipe poursuit désormais des essais cliniques via la spin-off Eyelumina.
