What this research studies

Parkinson's disease and related conditions, known as Lewy body diseases, are significant causes of dementia that can begin earlier in life than Alzheimer's. Many individuals carry specific changes in a gene called LRRK2, which can increase their risk for these conditions. Our previous work showed that LRRK2 influences how certain proteins clump together in brain cells and is also active in immune cells within the brain during disease. This project will closely examine how LRRK2 interacts with other proteins called Rab, focusing on a unique enzymatic process. By understanding these detailed interactions, we hope to uncover new ways to address the brain cell damage seen in these diseases.

Who could benefit from this research

Good fit: This foundational research aims to help individuals living with Parkinson's disease, Lewy body dementias, or those who carry LRRK2 gene mutations.

Not a fit: Patients seeking immediate treatment options may not directly benefit from this foundational research.

Why it matters

Potential benefit: If successful, this work could lead to new ways to treat or prevent the brain cell damage seen in Parkinson's and related dementias.

How similar studies have performed: This is a renewal of a successful prior grant, building on previous findings while exploring novel aspects of LRRK2 function.
