Today it is possible to correct almost any vision from nearsightedness and farsightedness to amblyopia. But what if the vision was gone completely? Russian scientists claim that the case is not hopeless and help to the person can come genetic engineering.
The technology, developed by scientists from Moscow state University, Institute of Bioorganic chemistry and Institute of higher nervous activity and neurophysiology of RAS, lies with genetic modification of certain cells of the eye that possess the ability to synthesize light-sensitive protein. To deliver the desired gene into the cells of the eyes and start the process of production of the protein will be used a special virus. As told in an interview to "Izvestia" head of the project, the neuroscientist Paul Balaban
"We have learned to plant in living cells a gene that produces a light sensitive protein. Due to this, almost any cell can become photosensitive. 90% of blind people optic nerve remains intact, and is about one million nerve cells. On them from the open eye gets the image, but the cells can't see, because they have no sensitivity. However, if each of these cells to teach to produce light-sensitive protein, they will be able to pass on to the brain quite a good image."
Now scientists have completed the first phase of testing and preparing to improve the technology, and full-scale clinical trial is scheduled to begin in 2021-2022 year.
the genome project required not only for research and study of genetic mutations, but in so-called personalized medicine.
Scientists from the China center of nanoscience and technology say they have managed to create and test the world's first Autonomous DNA nanorobots, capable of confronting malignant tumors.
