A new study shows that, when properly manipulated, a population of support cells found in the brain called astrocytes could provide a new and promising approach to treat Parkinson's disease. These findings, which were made using an animal model of the disease, demonstrate that a single therapy could simultaneously repair the multiple types of neurological damage caused by Parkinson's, providing an overall benefit that has not been achieved in other approaches. "One of the central...

Dopamine-producing cells die as result of cascade triggered by busy enzyme degradation cellular machines Scientists have identified the biological pathway that explains Gaucher disease (GD) patients' higher risk for developing Parkinson's disease (PD), according to research to be presented Tuesday, Dec. 17, at the American Society for Cell Biology annual meeting in New Orleans. GD is a hereditary disease in which the genes that encode the enzyme glucocerebrosidase are mutated, resulting...

redOrbit Staff & Wire Reports - Your Universe Online The human ability to locate and avoid objects in their peripheral field of vision with little more than a sideways glace could also be present in monkeys, according to new research in the journal Animal Cognition. Lau Andersen of the Aarhus University in Denmark and his colleagues trained five adult male rhesus monkeys in order to perform a short-latency, highly stereotyped localization task. They taught the creatures to touch...
