Retinal tissue may degenerate for a number of reasons. Among them are: artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P. or disease (usually hereditary). Retinitis pigmentosa, retinoschisis, lattic degeneration, and macular degeneration are characterized by progressive types of retinal degeneration.
In one of only two studies of its kind, a study from researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts demonstrates that non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision. The team developed nanoparticles to deliver therapeutic genes to the retina and found that treated mice temporarily retained more eyesight than controls.
The easy accessibility of the eye and the established link between specific genetic defects and ocular disorders offer hope for using gene therapy to provide long-term therapeutic benefit. Two reports in the current issue of Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc., describe the effective replacement of a human gene to preserve photoreceptor function in a mouse model of severe retinal degeneration. The articles are available free online.
It's safe to say that cilia, the hairlike appendages jutting out from the smooth surfaces of most mammalian cells, have long been misunderstood - underestimated, even.
Usher syndrome, an inherited condition involving both hearing and vision loss, is not a simply recessively inherited disease, a scientist will tell the annual conference of the European Society of Human Genetics today (Saturday). Dr. Hanno Bolz, Associate Medical Director of the Bioscientia Centre for Human Genetics, Ingelheim, Germany, and active in teaching and research at the University Hospital of Cologne, will say that his team's research challenges the traditional view that USH was inherited as a single gene disorder, and shows that it may result from at least two different genetic mutations.
Take a look at this: Scientists from Buffalo, Cleveland, and Oklahoma City made a huge step toward making the blind see, and they did it by using a form of gene therapy that does not involve the use of modified viruses.
Television's Six Million Dollar Man foresaw a future when man and machine would become one. New research at Tel Aviv University is making this futuristic "vision" of bionics a reality.
Researchers in University College Dublin (UCD) led by Conway Fellow, Dr Oliver Blacque have revealed new information about a gene implicated in Joubert syndrome and related cerebellar disorders (JSRDs) that are characterised by blindness, bone abnormalities, cystic kidneys, developmental delay and loss of muscle tone and control. The findings from this research, which is funded by Science Foundation Ireland, have been published today in a leading science journal, Journal of Cell Biology.
International Stem Cell Corporation, announced today that ISCO's Research and Therapeutic Development Group, together with a group of scientists from the University of California, Irvine (UCI), is starting a second phase of essential pre-clinical experiments to test retinal pigment epithelium derived from parthenogenetic stem cells. Follow on pre-clinical experiments will be conducted to rescue vision in disease models.
StemCells, Inc. today reported financial results for the fourth quarter and year ended December 31, 2009. The Company's results include the operations of Stem Cell Sciences Plc (SCS) since April 1, 2009.
An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide.
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.
Scientists at Emory University School of Medicine have discovered unexpected properties for a precursor to melatonin, the hormone that regulates sleep cycles.
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine have discovered new links between a common form of inherited blindness affecting children and a gene known as Abelson helper integration site-1 (AHI1).
Proteostasis Therapeutics announced today that it has entered into an exclusive license agreement with New York University for intellectual property related to discoveries from the laboratory of David Ron, M.D., Professor of Medicine and Julius Raynes Professor of Cell Biology at NYU Langone Medical Center’s Skirball Institute of Biomolecular Medicine.
Born with a retinal disease that made him legally blind, and would eventually leave him totally sightless, the nine-year-old boy used to sit in the back of the classroom, relying on the large print on an electronic screen and assisted by teacher aides. Now, after a single injection of genes that produce light-sensitive pigments in the back of his eye, he sits in front with classmates and participates in class without extra help. In the playground, he joins his classmates in playing his first game of softball.
StemCells, Inc. announced today new preclinical data showing that its human neural stem cells protect cone photoreceptors (cones) in the eye from progressive degeneration and preserve visual function long term.
Results for the quarter reflect the Company’s acquisition of the operations of Stem Cell Sciences Plc (SCS), a UK-based company focused on cell-based technologies for drug discovery and screening.
An international team of scientists and clinicians from the United States and Saudi Arabia are working to develop gene therapy for treating a rare, hereditary retinal disease.
New research has found that a diet which is low in trans fats and regularly includes nuts, olive oil and other foods containing omega-three fatty acids appears to offer some protection from the eye disease age-related macular degeneration (AMD).
If two people have the same genetic disease, why would one person go blind in childhood but the other later in life or not at all? For a group of genetic diseases - so-called ciliary diseases that include Bardet-Biedl syndrome, Meckel-Gruber syndrome, and Joubert syndrome - the answer lies in one gene that is already linked to two of these diseases and also seems to increase the risk of progressive blindness in patients with other ciliary diseases. The findings are published online this week at Nature Genetics.
