For the first time, scientists at the University of Wisconsin-Madison have made early retina structures containing proliferating neuroretinal progenitor cells using induced pluripotent stem (iPS) cells derived from human blood. And in another advance, the retina structures showed the capacity to form layers of cells — as the retina does in normal human development — and these cells possessed the machinery that could allow them to communicate information. (Light-sensitive...

A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States. The pig model was developed by researchers in the University of Louisville Department of Ophthalmology & Visual Sciences and at the National Swine Resource and Research Center at the University of Missouri. "We have previously relied mostly on rodent models to study...

A new gene therapy method developed by University of Florida researchers has the potential to treat a common form of blindness that strikes both youngsters and adults. The technique works by replacing a malfunctioning gene in the eye with a normal working copy that supplies a protein necessary for light-sensitive cells in the eye to function. The findings are published today (Monday, Jan. 23) in the Proceedings of the National Academy of Sciences online. Several complex and costly steps...

Members of a University of Pennsylvania research team have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs. The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man. "Every single abnormal feature that defines the disease in the dogs was corrected following treatment,"...

Research offers potential treatment for macular degeneration and retinitis pigmentosa Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A study by investigators at Mayo Clinic, Wayne State University and Johns Hopkins Medicine shows that steroids attached to the dendrimers target the damage-causing cells associated with neuroinflammation, leaving the rest of the eye unaffected and...

Research at Wayne State University, Mayo Clinic and Johns Hopkins offers potential treatment for macular degeneration and retinitis pigmentosa Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A collaborative research study among investigators at Wayne State University, the Mayo Clinic and Johns Hopkins Medicine shows that steroids attached to the dendrimers targeted the damage-causing...

Researchers at Ohio State University Medical Center and Nationwide Children´s Hospital have developed a viral vector designed to deliver a gene into the eyes of people born with an inherited, progressive form of blindness that affects mainly males. The vector is part of a clinical trial investigating the use of gene therapy to cure choroideremia, a disease that affects an estimated 100,000 people worldwide. The trial is being conducted by researchers at the University of Oxford in...

A UK man is being treated for the progressive genetic disorder, choroideraemia, in an attempt to reverse his blindness. Jonathan Wyatt was able to see normally until about the age of 19 when he began having problems seeing in the dark. He was told by doctors that his vision would get progressively worse until eventually going blind, reports BBC News. Poor eyesight didn´t stop Wyatt, now 63 years old, from a career as a barrister but 10 years ago he found himself having difficulty...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
