Scientists issued news in the capital today of a protein introduced in the cone of the eyes could help to fight retinitis pigmentosa, an illness that provokes blindness.
In studies with affected guinea pigs, researchers from the Friedrich Miescher Institute of Basel in Switzerland and the French centres, Inserm and Sight Institute succeeded in bringing sight back to those injected with the protein. The researchers concentrated on the cones as in some cases of the disease they receive the most damage. The authors of the study suggested that the grafted protein plays a part in uniting the photic stimulation to ion transport which reproduce a biological photoelectric system that contribute to recovering sight.
In actuality at the Sight Institute experiments were carried out with human retinas developed so as to make them compatible with the mother cells. Retinitis pigmentosa is an hereditary pathology that can be caused by multiple genetic flaws.
Swabs, of the cells that control night vision, are the ones that were most affected by the illness, whose main symptom is the appearance of dark lines on the retina. When retinitis deteriorates, peripheral vision is gradually lost. The first signs appear in childhood, but it doesn’t usually develop until adulthood.
