Official title
UAB Neuroinflammation in Parkinson's Disease - TSPO-PET Substudy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of this substudy is to measure the concentration and the regional brain distribution of activated brain microglia/macrophages using the PET ligand \[18F\]DPA-714 in participants enrolled in the UAB Innate and Adaptive Immunity in Parkinson's Disease (Clinical Research Core) and Longitudinal \[18F\]DPA-714 Imaging in a Parkinson Disease Cohort studies. The PET tracer \[18F\]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation. The amount and distribution of \[18F\]DPA-714 in the brain will be correlated to clinical data acquired through the separate ongoing UAB Innate and Adaptive Immunity in Parkinson Disease (Clinical Research Core) and Longitudinal \[18F\]DPA-714 Imaging in a Parkinson Disease Cohort studies. The primary objective of this study is to determine if patients with PD have higher levels of neuroinflammation than healthy controls as measured with \[18F\]DPA-714-PET/MRI.
