New research suggests add role for pbt against Alzheimers.
Melbourne, Australia – May 3, 2004 –The Journal of Biological Chemistry has published findings by researchers for Prana Biotechnology Limited (NASDAQ: PRAN; ASX: PBT) suggesting an additional mechanism for the action of Prana’s technology in delaying the progress and severity of Alzheimer’s disease.
Prana’s MPACs (metal protein attenuating compounds) have previously been shown to lower the levels of beta-amyloid in the brain — the main component of amyloid plaques that are a feature of Alzheimer's disease.
The new research suggests that that these MPACs may also be effective in preventing beta-amyloid from attaching itself to and damaging COX-2, the key enzyme that mediates inflammation in the brain often associated with Alzheimer’s disease.
Levels of beta amyloid/COX-2 complexes were found to be elevated significantly in the brains of patients with Alzheimer's disease.
Professor Ashley Bush of Harvard Medical School and Chief Scientific Consultant to Prana was the senior author on the paper: “COX-2 has been implicated in Alzheimer's disease, but studies of COX-2 inhibitors (anti-inflammatory drugs) have been disappointing.
Our current findings explain how the interaction of beta-amyloid with brain copper corrupts the normal metabolism of COX-2 in Alzheimer's disease.
These findings further validate Prana’s MPAC drug approach, which targets the adverse metal interaction with amyloid. MPACs stop the beta-amyloid/metal complex from damaging COX-2.
These findings also may explain why anti-inflammatory drugs would not be effective in Alzheimer's disease.”
