Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid. The formation of amyloid leads to cell death and neurodegeneration. The most important cellular events perturbed by the formation of amyloid aggregates are unclear. Recent evidence suggests that sterols (including cholesterol) have an important role in cellular toxicity. This study will examine the molecular basis for this, enhancing our understanding of the amyloid diseases and could ....Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid.

Summary
Alzheimer's disease (AD) is becoming more common with our growing aged population and currently no treatment exists that halts disease progress. The increasing health costs of AD underscore the need for development of any treatment that will slow or halt AD pathogenesis. By understanding the mechanisms of action of a drug [latrepirdine] that has recently shown some promise in phase II clinical trials, related drugs that are more specific and potent will be developed.
New High Thoughput Animal Models To Investigate Amyloid Beta Toxicity

Summary
Amyloid-beta is widely considered to cause Alzheimer’s disease. The majority of amyloid-beta in Alzheimer's disease brains is found as shortened forms. The role of these shortened forms is uncertain and are not being tested in current animal models. We propose to develop new models to determine and compare their respective toxic effects, and to use these new models to help identify drugs to treat Alzheimer's disease.

Summary
Amyloidoses are a group of diseases in which protein is abnormally deposited in various organs of the body. The prototypic amyloidosis is Alzheimer's disease (AD), a dementia causing-illness in which a protein known as Abeta is deposited in the brain. The central aim of my research is to understand the molecular etiology of AD and other amyloidoses, with a view to identifying new targets for drug development.
