Photoreactive compounds developed by LMU scientists directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain and certain types of visual impairment. All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of...

Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients...

Red Lights At Night Better Than White When It Comes To Mood

Brett Smith for redOrbit.com - Your Universe Online People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation. Study researchers from The Ohio State University found hamsters that were exposed to blue lights at night experienced the worst mood disruptions, followed closely by white lights, when compared to hamsters that spent their nights in a dim red light. "Our...

Researchers Find Easier Way To Perform Macular Degeneration Eye Test
2012-10-08 12:33:58

Lawrence LeBlond for redOrbit.com - Your Universe Online Age-related Macular Degeneration (AMD) is a condition that generally occurs in people over the age of 50, but also occurs in higher numbers of people who smoke, who are white, and people who have a family history of the often debilitating condition. And for those who had gone through AMD testing, they had generally had to sit in a darkened room for 20 minutes before testing had begun. But now, researchers from Australia´s...

Research conducted at the Angiogenesis Laboratory at Massachusetts Eye and Ear Infirmary, has for the first time, identified the mode of death of cone photoreceptor cells in an animal model of retinitis pigmentosa (RP). This groundbreaking study, led by Demetrios G. Vavvas, M.D., Ph.D., and including Joan W. Miller, M.D., Mass. Eye and Ear/Mass General Hospital Chief of Ophthalmology and Chair of Ophthalmology at Harvard Medical School, has further identified the receptor interacting protein...

Scientists funded by the Medical Research Council (MRC) have shown for the first time that transplanting light-sensitive photoreceptors into the eyes of visually impaired mice can restore their vision. The research, published in Nature, suggests that transplanting photoreceptors — light-sensitive nerve cells that line the back of the eye — could form the basis of a new treatment to restore sight in people with degenerative eye diseases. Scientists from UCL Institute of...

New York University biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra. Their findings, which appear in the journal Nature, focus on how the visual system functions in order to preserve the fidelity of color discrimination throughout the life of an organism. They also offer new insights into how genes controlling color detection are turned on and off. Many biologists study how different cells develop to...

After more than three decades of research, University of Pennsylvania veterinarians and vision-research scientists, with associates at Cornell University, have identified a gene responsible for a blindness-inducing disease that afflicts dogs. In the process, the Penn scientists may have discovered clues about how retinal cells, and perhaps even neurons, can be regenerated. The research was conducted by Gustavo D. Aguirre, William A. Beltran, Agnes I. Berta and Sem Genini of Penn's School...

New research in the FASEB Journal provides insight into the molecular basis of one form of retinal degeneration, Enhanced S-Cone Syndrome also known as Goldman-Favre Syndrome A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome. In the...

Johns Hopkins researchers uncover the source of the visual system's 'false alarms' On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by...
