Hundreds of thousands of people with failing eyesight have been given fresh hope of a cure after gene therapy techniques were used to treat a teenager.
The treatment transformed the life of a severely visually impaired 18-year-old. Healthy genes were injected into one eye, leading to a significant improvement.
Eh? How does this work? I was under the (obviously mistaken) impression that gene therapy only worked if you could get it into the cells that then replicated. That is, that you needed to get it into the actual genetic structure of the individual and that thus such therapy really only worked upon hte next generation.
Clearly, I\’m wrong, but seriously? Just inject the healthy genes into the afflicted organ and everything starts to work?
