Promising Alzheimer's drug boosts toxic protein

CHICAGO (Reuters) – Dimebon, Medivation Inc's Grande Taille Watches promising experimental Alzheimer's drug, significantly raised levels of a toxic protein in the brains of mice, yet has been shown to delay thinking problems in human dementia patients, U.S. researchers said on Wednesday. "This is an unexpected result," said Dr. Samuel Gandy, a researcher at Mount Sinai School of Medicine in Master Control Watches New York, whose findings were presented at an Alzheimer's meeting in Vienna. The study raises new questions about how the drug works and new worries about drugs meant to remove telltale clumps of a protein called beta amyloid from the brain as a way to reverse Alzheimer's Master Ultra Thin Watches disease. Researchers are not sure whether amyloid is a cause or a symptom of Alzheimer's but, either way, getting rid of it had appeared to be a good thing. "We think we want amyloid levels to go down," Gandy said in a telephone interview. "Here is this Reserve de Marche Watches compound that is looking very promising clinically that is making amyloid levels go up." Dimebon, first sold in Russia as an antihistamine, is being developed jointly with Pfizer Inc, maker of the Alzheimer's drug Aricept. Researchers see Dimebon as the best hope for a new treatment for the incurable, mind-robbing Reverso Watches disease that affects 26 million people globally. Now in late-stage testing, Dimebon seems to delay thinking problems in people but it is not clear how. "We wanted to know what Dimebon was doing to amyloid," Gandy said. His team tested mice genetically engineered to have a human form of Reverso Classique Watches Alzheimer's. The drug increased amyloid outside nerve cells.
