But the CEP290 gene is too big to be cargo for viruses. In the future, more research is needed to tweak the ability of the infrared sensitive proteins to different wave lengths of light that will also enhance the remaining vision. Although the treated eyes showed vision improvement, as measured by the patient’s ability to navigate an obstacle course at differing light levels, it is not a permanent fix. Many disease genes have counterparts, which serve similar functions but are expressed in distinct cell types. Berkeley scientist Jennifer Doudna won the 2020 Nobel Prize for her work on the revolutionary gene-editing technology known as CRISPR. In my mind, as well as the minds of many other scientists, CRISPR-mediated therapeutic innovation absolutely holds immense promise. The second reason is that retinal tissue in the eye is shielded from the body’s defense mechanism, which would otherwise consider the injected material used in gene therapy as foreign and mount a defensive attack response. In the future, more research is needed to tweak the ability of the infrared sensitive proteins to different wave lengths of light that will also enhance the remaining vision. Sadly, many patients continue losing their sight despite VEGF treatment and Kodiak has an elegant solution to the problem. Read the original article. An upcoming human study will use CRISPR genome editing technique to treat an eye disorder that causes blindness. The researchers demonstrated this approach, inspired by the ability of snakes and bats to see heat, by endowing mice and postmortem human retinas with a protein that becomes active in response to heat. According to the World Health Organization, at least 2.2 billion people in the world have some form of visual impairment. This form of Leber congenital amaurosis is caused by mutations in a gene that codes for a protein called RPE65. The heat warms a specially engineered gold particle that the researchers introduced into the retina. This particle binds to the protein and helps it convert the heat signal into electrical signals that are then sent to the brain. The scientists at Editas Medicine first showed safety and proof of the concept of the CRISPR strategy in cells extracted from patient skin biopsy and in nonhuman primate animals. This is due to the lack of technologies that can fix the mutated genetic code in the DNA of the cells of the patient. Researchers at U.S.-based Editas Medicine and Ireland-based Allergan have administered CRISPR for the first time to a person with a genetic disease. However, that doesn't mean it's too late to get in on this trend before it takes off in 2020. In this book, experts summarize the state of the art in this exciting field.
