McGill University Health Centre An international research project, led by the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal, reports that a new oral medication is showing significant progress in restoring vision to patients with Leber congenital amaurosis (LCA). Until now, this inherited retinal disease that causes visual impairment ranging from reduced vision to complete blindness, has remained untreatable. The study is published today in the scientific...

For Your Eyes Only: Understanding How Sight Evolved

Brett Smith for redOrbit.com - Your Universe Online The ability to look out for predators or see a distant source of water has allowed humans to get where we are today, but how did our sense of vision evolve throughout time? In a newly published research review, Trevor Lamb, a neuroscientist at the Australian National University, decided to look into several questions surrounding the evolution of the human eye. "There are profound questions about the eye which are still not easy to...

Research led by Minghao Jin, PhD, Assistant Professor of Ophthalmology and Neuroscience at the LSU Health Sciences Center New Orleans Neuroscience Center of Excellence, has found a protein that protects retinal photoreceptor cells from degeneration caused by light damage. This protein may provide a new therapeutic target for both an inherited retinal degenerative disease and age-related macular degeneration. The paper is published in the February 13, 2013 issue of the Journal of Neuroscience....

(Ivanhoe Newswire) "“ Turns out our sensitivity to seeing in color is not only due to cone cells in the retina, but also through the thyroid gland by controlling which visual pigment is produced in the cones. Research conducted on mice and rats has revealed that the production of visual pigment present in mature cones is regulated by the thyroid hormone. The team of researchers at the Max Planck Institute for Brain Research in Frankfurt/M., along with colleagues at the University of...

'Out of the blue' discovery marks new direction in phototransduction studiesA UC Irvine research team led by Todd C. Holmes has discovered a second form of phototransduction light sensing in cells that is derived from vitamin B2. This discovery may reveal new information about cellular processes controlled by light.For more than 100 years, it had been believed that the phototransduction process was solely based on a chemical derived from vitamin A called retinal. Phototransduction is the...

Research by Johns Hopkins sensory biologists studying fruit flies, has revealed a critical step in fly vision. Humans with problems in this same step suffer retinal dystrophies, which manifest as visual defects ranging from mild visual impairments to complete blindness. The article, published Jan. 26 in Current Biology paves the way for using the fruit fly to screen for therapies to treat human retinal degeneration. Retinal dystrophies result from inherited defects in nearly every step of the...

Fetal alcohol spectrum disorder (FASD) and Fetal alcohol syndrome (FAS) cause malformations in babies, including facial defects, short stature, and mental and behavioral abnormalities. The African frog, Xenopus, is a valuable tool for understanding early vertebrate development since these embryos are large, easy to work with and very responsive to environmental cues. New research uses this system to address the mechanism underlying the characteristics associated with maternal consumption of...

By Altun, Ahmet Yokoyama, Shozo; Morokuma, Keiji ABSTRACT The protein environments surrounding the retinal tune electronic absorption maximum from 350 to 630 nm. Hybrid quantum mechanical/molecular mechanical (QM/MM) methods can be used in calculating excitation energies of retinal in its native protein environments and in studying the molecular basis of spectral tuning. We hereby review recent QM/MM results on the phototransduction of bovine rhodopsin, bacteriorhodopsin, sensory rhodopsin...

In findings that could lead to curing some forms of congenital blindness through gene therapy, researchers at UCLA have discovered that RPE65, a gene missing in infants born with the blinding disease Leber congenital amaurosis, is also a key enzyme in the visual cycle. The identity of this enzyme has long been a mystery to scientists. The study, "Rpe65 is the Retinoid Isomerase in Bovine Retinal Pigment Epithelium," is published in the Aug. 12 issue of Cell magazine. "We were amazed when we...
