One day, blind people may have their sight restored thanks to a new method of molecular therapy. It makes use of genes acquired from an unlikely source, algae. Recently a group of American scientists proved, that the therapy is successful in murine model. During a described trial (1), solution containing viruses, which carry the algal genes, was injected into the eyes of blind mice. It turned out that retinal cells became sensitive to light and mice could easily find their way out of a maze. According to WHO (2), it has been estimated that about 39 million people worldwide suffer from a severe vision impairment. Perhaps we could put an end to this problem by using a power of nature mixed with technological advance. Read full text »
