Recent Research

Research Focus

Dr. Cookson's research program investigates the cellular and molecular mechanisms underlying Parkinson's disease, with a particular emphasis on:

• LRRK2 biology: Understanding the function of LRRK2 and how mutations cause Parkinson's disease
• Parkinson's disease genetics: Identifying genetic risk factors for sporadic PD
• Protein homeostasis: Studying how cells clear damaged proteins
• Animal models: Developing and characterizing PD model systems
• Membrane trafficking: Understanding how cellular transport pathways are affected in PD
• Alpha-synuclein biology: Investigating the function and dysfunction of alpha-synuclein

Key Discoveries

Research Contributions

LRRK2 Kinase Function

Dr. Cookson's research has been pivotal in understanding LRRK2 (leucine-rich repeat kinase 2), one of the most common genetic causes of Parkinson's disease. His lab demonstrated that LRRK2 phosphorylates Rab proteins, which are key regulators of membrane trafficking in cells. This discovery provided a molecular link between LRRK2 function and cellular transport pathways that may be disrupted in PD[@phosphoproteomics2016].

The Cookson laboratory has characterized:

• The kinase domain structure of LRRK2
• Substrate specificity of LRRK2
• Pathogenic mutations that affect LRRK2 activity
• Cellular pathways affected by LRRK2 dysfunction
• Therapeutic targeting of LRRK2

Genetic Architecture of Parkinson's Disease

Through genome-wide association studies and other genetic approaches, Dr. Cookson has contributed to identifying numerous genetic risk factors for sporadic Parkinson's disease. His work has helped reveal that Parkinson's disease is genetically complex, with multiple genes and variants contributing to disease risk. Key findings include:

• Identification of risk variants in LRRK2, GBA, and other genes
• Understanding of gene-environment interactions in PD
• Elucidation of pathways enriched for PD risk genes
• Insights into the genetic overlap between PD and other neurodegenerative diseases

Protein Quality Control

A significant focus of Dr. Cookson's work involves understanding how cells handle misfolded proteins. His research has explored the autophagy-lysosome and ubiquitin-proteasome systems, which are responsible for clearing damaged proteins that can accumulate in neurodegenerative diseases. This work has implications for understanding:

• How mutations in PD genes affect protein clearance
• Why certain [neurons](/entities/neurons) are vulnerable to protein aggregation
• Therapeutic strategies to enhance protein clearance

Membrane Trafficking and Synaptic Function

Dr. Cookson's research has revealed important connections between PD genes and synaptic function. His work on LRRK2 and Rab proteins has shown how mutations affect:

• Synaptic vesicle trafficking
• neurotransmitter release
• Neuronal connectivity
• Dendritic spine morphology
