Dystonia Related Research

Jason Dunn and Mike Delise recently returned from the Children & Family Dystonia Symposium in Chicago, where they were presented with Star Awards. The Dystonia Medical Research Foundation (DMRF) recognized Dunn and Delise for their efforts to promote greater public awareness of dystonia, a neurological disease. "I think this is probably the only time in my life that I am speechless," says Dunn. "I wasn't expecting this award at all." "Bringing awareness and donations to the Dystonia Medical Research Foundation is the single most important thing we can do--this is how a cure will be found," says Delise. "The people who deserve this award are all the people who have dystonia who bring awareness every minute of their life. Jason is my hero and to be able to help your hero is a thrill for me." Dunn began exhibiting unusual postures and an awkward gait at age 6. While most children this age are mastering their abilities to run, jump, and so

A new atlas of gene expression in the mouse brain provides insight into how genes work in the outer part of the brain called the cerebral cortex. In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language. Mice and people share 90 percent of their genes so the atlas, which is based on the study of normal mice, lays a foundation for future studies of mouse models for human diseases and, eventually, the development of treatments. Researchers from the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, and from Oxford University in the United Kingdom, published a description of the new atlas in the Aug. 25, 2011, journal Neuron. The study describes the activity of more than 11,000 genes in the six layers of brain cells that make up the cerebral cortex. "This study shows the power of genomic technologies for making unexpected discoveries about the basic biology of lif

A molecule which can stop the formation of long protein strands, known as amyloid fibrils, that cause joint pain in kidney dialysis patients has been identified by researchers at the University of Leeds. The discovery could lead to new methods to identify drugs to prevent, treat or halt the progression of other conditions in which amyloid fibrils play a part, including Alzheimer's, Parkinson's and type II diabetes. The research, funded by the Biotechnology and Biological Sciences Research Council and the Wellcome Trust, is published August 28 in Nature Chemical Biology. The team -- from Leeds' Astbury Centre for Structural Molecular Biology and Faculty of Biological Sciences -- found that an antibiotic known as Rifamycin SV was able to prevent the protein β2microglobulin (β2m) from forming into fibrils. β2m is known to accumulate in renal dialysis patients and forms fibrils within the joints, causing extreme pain and arthritis. By using a specialised analytical technique

Scientists at Northwestern University report a surprising discovery that offers a possible new route for the treatment of neurodegenerative diseases. In a study of the transparent roundworm C. elegans, they found that a genetic switch in master neurons inhibits the proper functioning of protective cell stress responses, leading to the accumulation of misfolded and damaged proteins. Neurodegenerative diseases, ranging from Huntington's and Parkinson's to amyotrophic lateral sclerosis and Alzheimer's, are believed to stem from early events that lead to an accumulation of damaged proteins in cells. Yet all animals, including humans, have an ancient and very powerful mechanism for detecting and responding to such damage, known as the heat shock response. "Why are these diseases so widespread if our cells have ways to detect and prevent damaged proteins from accumulating?" said Richard I. Morimoto, who led the research together with postdoctoral colleague Veena Prah
