Protein Aggregates in Neurodegenerative Diseases

Protein aggregates in neurodegenerative diseases:
Question marks highlight poorly understood processes that are potential therapeutic targets


Many common neurodegenerative diseases, including Alzheimer’s Disease, Parkinson’s Disease, ALS (Lou Gehrig disease) and frontotemporal dementia are associated with aggregation of specific proteins in the brain. Recent evidence shows that these aggregates behave as prions and spread across cell boundaries during disease progression. However, we lack an understanding of the mechanisms driving these processes and the downstream effects on neuronal function.

We hypothesize that specific proteostasis factors control formation, spread and clearance of protein aggregates associated with neurodegenerative diseases. Using our functional genomics approach in human iPSC-derived neurons, we aim to identify these factors to shed light on the cellular mechanisms underlying neurodegenerative diseases, and to identify potential therapeutic targets. In collaboration with colleagues at the IND, we combine several cutting-edge technologies to discover and develop effective drugs for neurodegenerative diseases.

Our research on neurodegenerative diseases is funded by the Paul G. Allen Family Foundation (Allen Distinguished Investigator Award), the Alzheimer's Association, the National Institutes of Neurological Disorders and Stroke / National Institutes of Health, the California Institute for Quantitative Biomedical Research / Calico Longevity Award and the Glenn Foundation for Medical Research.
