Immunosuppression for Parkinson's disease - a new therapeutic strategy?
Caroline Williams-Gray is a Principal Research Associate in the Department of Clinical Neurosciences, University of Cambridge, and an honorary consultant neurologist specializing in Parkinson’s disease and movement disorders. She leads a translational research group investigating the clinical and biological heterogeneity of PD, with the ultimate goal of developing more targeted therapies for different Parkinson’s subtypes. Her recent work has focused on the theory that the immune system plays a significant role in mediating the heterogeneity of PD and its progression. Her lab is investigating this using blood and CSF -based immune markers, PET neuroimaging and neuropathology in stratified PD cohorts; and she is leading the first randomized controlled trial repurposing a peripheral immunosuppressive drug (azathioprine) to slow the progression of PD.
Human stem cell models of Alzheimer’s disease and frontotemporal dementia
The development of human induced pluripotent stem cells (iPSC) and their subsequent differentiation into neurons has provided new opportunities for the generation of physiologically-relevant, in vitro disease models. I will present our work using iPSC to modal familial Alzheimer's Disease (fAD) and Frontotemporal Dementia (FTD). We have investigated the mutation-specific effects of APP and PSEN1 mutations on Abeta generation in neurons generated from individuals with fAD, revealing distinct mechanisms that may contribute to clinical heterogeneity in disease. I will also discuss our work to understand the developmental and pathological changes to tau that occur in iPSC-neurons, particularly the challenges of understanding tau pathology in a developmental system, tau proteostasis and how iPSC-neurons may help us identify early signatures of tau pathology in disease.
