Prana Biotechnology Presents at the 9th International Conference on Alzheimer's Disease Co-founding scientist to discuss new data on the interaction of cholesterol with beta-amyloid and brain metals PHILADELPHIA, July 19 /PRNewswire-FirstCall/ -- Dr. Ashley Bush, chief scientific consultant and co-founder of Prana Biotechnology Limited (NASDAQ: PRAN)(ASX:PBT) is scheduled to present a lecture tonight at the 9th International Conference on Alzheimer's Disease and Related Disorders (ICAD), a specialist international symposium in Philadelphia at the Pennsylvania Convention Center, Ballroom A/B. The event will commence at 5:30 PM. Dr. Bush intends to present a lecture entitled "Clioquinol and the Metal- Protein Attenuating Compounds (MPACs*) in the treatment of Alzheimer's disease" at a session devoted to the development of therapeutic strategies. Based on the hypothesis that beta amyloid is a key player in the onset and progression of Alzheimer's disease, Prana maintains that it is the inappropriate interaction of beta amyloid with brain metals copper and zinc that leads to the progression associated with the disease. As part of his remarks, Dr. Bush intends to discuss how clioquinol detects amyloid pathology in brain tissue and how the drug arrives at the appropriate biochemical target in living transgenic mice and in post-mortem tissue from patients with Alzheimer's disease. Dr. Bush and his co-workers at the University of Melbourne and Massachusetts General Hospital have developed this theory over 15 years of research. For much of this time, the research community has been sceptical toward what was a major departure from the more favoured theories. Invitations to present the MPAC approach at premier conferences such as ICAD demonstrate the increasing support for Prana's technology in the Alzheimer's community. Co-founding Scientist of Prana, Dr. Rudolph E. Tanzi, Professor of Neurology at Harvard Medical School said, "This conference is regarded as an important event, not only for scientists and medical practitioners in the industry, but also for the millions of patients worldwide who have Alzheimer's, This invitation to speak to international peers about the scientific basis for Prana's MPAC technology is an indication that our theories have achieved considerable acceptance." Also at ICAD, on Wednesday July 21, Dr. Bush is scheduled to give an invited lecture that will review the basic neuroscience describing the involvement of brain copper and zinc in Alzheimer pathology. New data is expected to be presented on the interaction of cholesterol with beta-amyloid and brain metals, which may play a key role in the sequence of events that leads to dementia. The possibility that beta-amyloid participates in the functional regulation of copper levels in health will be discussed. (*MPACs, or Metal-Protein Attenuating Compounds are compounds that bind metals to prevent their interactions with proteins.) International Conference on Alzheimer's Disease (ICAD) The ICAD is the world's leading forum on dementia research, and provides the opportunity for more than 5,000 attending researchers to share knowledge and develop creative new approaches to increasing the understanding of Alzheimer's.
