PET imaging of neuropathological changes in animal models of Alzheimer's disease

​Description of Research

We aim to use positron emission tomography (PET) to investigate the effects of endocannabinoid modulation, brain energy metabolism, neuroinflammation, norepinephrine function, and beta-amyloid plaque and tau formation, as well as their connections to each other in animal models of Alzheimer's disease (AD). Improving our understanding of AD pathophysiology requires specific and sensitive non-invasive methods for the functional characterisation of brain function in vivo. The exploration of these connections and their respective
 oles in neuronal loss and AD neurodegeneration has important implications for both clinical practice and for future therapeutic interventions.
