RESTAURED COLOUR BLINDNESS

Jay Neitz and other researchers of Washington University, have achieved that squirrel monkeys recover the capacity to distinguish the entirety of colors a defect acquired congenitally. For it, they introduced into monkeys, the faulty genes embedded to virus that reached and restored the lost capacity of sensitive cells to light, located in the retina. Until now it was thought that it was impossible to manipulate the mature human brain, adding it new sensorial information. Introduced genes contain the necessary DNA to restore to the normality sensitive cells to the light making them possible to distinguish the red of the green colours (more common visual defect of blindness to colors, linked to X chromosome). As long as cured squirrel monkeys remain stable after 2 years, it is thought that this cure will be able to be extended to other linked defects to chromosome X, as Hemophilia A.

CEGUERA A COLORES

Jay Neitz y otros investigadores de la U. de Washington, han logrado que monos ardilla recuperen la capacidad de distinguir la totalidad de los colores, defecto adquirido congénitamente. Para ello introdujeron los genes faltantes adosados a virus que alcanzaron y restauraron la capacidad perdida de células sensibles a la luz, ubicadas en la retina. Hasta hoy, se pensaba que era imposible manipular el cerebro humano adulto, añadiéndole nueva información sensorial. Los genes introducidos contienen el DNA necesario para restaurar a la normalidad células sensibles a la luz haciendo posible distinguir el rojo del verde (defecto visual más común de ceguera a los colores, ligado al cromosoma X). En tanto los monos ardilla curados permanecen estables luego de 2 años, se piensa que esta cura podrá ser extendida a otros defectos ligados al cromosoma X, como la Hemofilia A.
