Our research aims to understand the basis of neurodeneration in age-related neurodegenerative diseases. We are using multiple approaches in several disease models to systematically uncover the common pathways in neurodegeneration and to identify methods to prevent or treat the process. A key focus on the lab has been Alzheimer’s disease (AD). In this disease, there is a characteristic deposition of the 42-residue amyloid β protein (Aβ42) demonstrating the failure of protein homeostasis in the brain. Similar protein accumulation is characteristic of a number of other degenerative diseases in the CNS such as age-related macular degeneration (ARMD) as well as somatic tissues as in islet amyloid. The general assumption has been that the neurodegeneration is caused by specific toxicity of the accumulated protein aggregates. Interestingly cholesterol has been identified as a risk factor in AD and also in ARMD. Both diseases show extracellular deposits of amyloid. Our studies are evaluating the role of amyloid and the secretases in AD as well as retinal generation to understand common mechanisms of degeneration. We hope and expect that the detailed evaluation of the common pathways of degeneration in AD and forms of retinal degeneration will identify ways to prevent and treat these devastating diseases.
