There\u2019s a new vision for a rare, inherited condition.<\/p>\n

Recent research<\/a> has identified a one-time treatment that may repair damaged retinas and even reverse vision loss<\/a>.<\/p>\n

This treatment, tested on an unexpected source, also raises the prospect of repairing nerve cells in mammals, a feat once thought impossible.<\/p>\n

\"MacroA one-time treatment may reverse vision loss and heal retina damage caused by a rare, genetic condition in adults. Monkey Business \u2013 stock.adobe.com<\/p>\n

Faulty copies of the CaBP4 gene<\/a> cause poor vision from childhood by creating deficiency of a protein necessary for vision and signal transmission in the retina.<\/p>\n

This protein can also affect dogs, leading researchers from Michigan State University to create a potential remedy by injecting the retinas of the animals with a harmless virus carrying a working copy of the gene.<\/p>\n

The single-dose therapy improved vision in dim light, which is where the CaBP4 protein deficiency makes the most difference. <\/p>\n

The treatment also helped areas of the damaged retina degrade less, while the outer plexiform layer that holds crucial connectors for vision and the synaptic ribbons inside the eye\u2019s light-sensing cells expanded.<\/p>\n

Growth of both the outer plexiform layer and synaptic ribbons is stunted when the CaBP4 gene isn\u2019t working properly. The researchers compared this underdevelopment to building blueprints.<\/p>\n

\u201cOne can essentially discuss the mutations in the retinal gene as a typo in a blueprint that makes the instructions incomprehensible to the system, resulting in a faulty design and subsequent vision loss,\u201d study lead Billie Beckwith-Cohen said in a press release.<\/a><\/p>\n

The treatment allows the growth of a layer in the eye that didn\u2019t form as it typically would have during retinal development, establishing that the outer plexiform layer of the retina has the ability to change. <\/p>\n

It also allows for synaptic features that support proper vision to grow properly, building a better support system for the whole retinal neural network.<\/p>\n

Another highlight of the single-dose treatment is its ability to repair years of damage.<\/p>\n

The team saw evidence of nerve cells being rewired even after years of stunted growth in the eye and ensuing damage to nerve cell connections.<\/p>\n

The benefits were long-lasting as well, as seen in follow-up periods three years after the initial treatment.<\/p>\n

While the genetic condition is rare in both humans and dogs, the findings could provide other methods for repairing damaged neural networks.<\/p>\n

One such application would look at the role that calcium signaling plays in handling cell communication in the eye \u2014 which also involves CaBP4.<\/p>\n

The treatment has yet to be applied to humans. However, researchers are confident it will work.<\/p>\n

\u201cOur results show that gene therapy is not only capable of restoring retinal function but is also able to establish a nearly normal anatomical arrangement in the OPL of the retina,\u201d they wrote in the paper.<\/p>\n","protected":false},"excerpt":{"rendered":"There\u2019s a new vision for a rare, inherited condition.
