Researchers announced this week they have developed a new form of eye repair treatment where stem cells are used to grow new eye tissue for patients suffering from cataracts, the primary cause of blindness and other eye conditions, MNT reports. A dozen infants who were born with the disease have recover their sight after doctors used…

Gene Therapy Wins Big at Portugal’s Champalimaud Foundation

Seven scientists in the United States and Britain who have come up with a revolutionary gene therapy cure for a rare genetic form of childhood blindness won a 1 million euro ($1.15 million) prize Tuesday, Portugal’s Champalimaud Foundation said.

Established in 2006, the annual award for work related to vision is one of the world’s largest science prizes, more than the latest 9 million Swedish crown ($987,000) Nobel Prize in Physiology or Medicine.

“This is the first, and still only, example of successful gene therapy in humans that corrects an inherited genetic defect and is therefore a milestone in medical therapeutics,” said Alfred Sommer, Dean Emeritus of the Johns Hopkins Bloomberg School of Public Health and chairman of the award jury.

One of those honored, Michael Redmond of the National Eye Institute in Maryland, had traced the cause of the disease, Leber congenital amaurosis (LCA), to a mutated gene.

Three cooperating research teams later managed to replace the gene in the eye, restoring vision to treated children and adults with one form of LCA and “enabling the entire field of gene therapy for human disease,” the foundation said.

These teams are comprised of U.S. scientists Jean Bennett and Albert Maguire; Samuel Jacobson and William Hauswirth; and Britons Robin Ali and James Bainbridge.

Their gene augmentation therapy involved the delivery of healthy genes using engineered harmless viruses, described by the foundation as “an elegant solution.”
