A group of scientists managed to restore sight to blind mice. Although mice could see on a temporary basis, this is a very important discovery in this field of research to regain vision.
Group of researchers it scientists from the universities of Berkeley, Munich and Washington, achieving the vision of mice to restore blind people.
treatment based on a substance called chemical AAQ, which got cells blind ” of the to be sensitive to light back to the retina. This method is beneficial for people who have degenerative blindness and this can retrieve the view.
This discovery may offer a treatment for retinitis pigmentosa or macular degeneration the, these are diseases that affects the ability to feel the light of the eyes, and that this method could gradually regain the view.
Mice were injected directly in the eyes, which meant that they could detect the light. This substance works as a fotointerruptor that binds to the ion channel proteins on the surface of the cells of the retina. The substance is activated by light, and this modifies the flow of ions through channels by activating neurons.
Scientists discovered that mice recovered the sensitivity to light, because the pupils of the mice are crontrajeron to direct. This research should continue to evaluate the effectiveness of the treatment, since the effect of the substance lasts 24 hours and should be injected again.
