简要总结
The overall objective of this study is to determine whether LRRK2 kinase activity and/or mitochondrial DNA (mtDNA) damage could serve as potential biomarkers in PD.
详细描述
Primary Objectives:
- Assess the levels of phosphorylated LRRK2 and LRRK2-phosphorylated Rabs, as measures of LRRK2 kinase activity, in PBMCs and neutrophils from LRRK2 PD, idiopathic PD, non-manifesting LRRK2 mutation carriers and healthy controls.
- Assess the levels of mtDNA damage in buffy coat from LRRK2 PD, idiopathic PD, non-manifesting LRRK2 mutation carriers and healthy controls.
- Correlate LRRK2 kinase activity to mtDNA damage in blood from LRRK2 PD, idiopathic-PD, non-manifesting LRRK2 mutation carriers and healthy controls.
Secondary Objectives:
- To assess the ability of the network to efficiently conduct a study involving biosample collection for PD research. Efficiency will be assessed using measures of the time taken to meet specific milestones within the study.
- To assess the ability of the network to collect high quality biospecimens adhering to agreed-upon, standardized protocols
- To gauge the willingness of participants to participate in subsequent Fox BioNet studies
