Following an undergraduate in Human Genetics at Trinity College Dublin, Aoife obtained her PhD in Medical Genetics from the University of Cambridge in 2013. She then took up a post-doctoral position with Prof. Dean Nizetic in Queen Mary, University of London, developing a world first isogenic human induced pluripotent stem cells (hiPSCs) model for the study of Down Syndrome and Alzheimer’s Disease. She participated also in the research conducted as part of The London Down Syndrome Consortium (LonDownS) funded by The Wellcome. She continued working with Prof. Nizetic at Lee Kong Chian School of Medicine in Singapore and in 2016 received a WHRI-ACADEMY/Marie Curie fellowship to develop technologies for enhancement of Down syndrome related cellular phenotypes using human induced pluripotent stem cells. Aoife recently moved back to London with a research fellowship from the Jérôme Lejeune Foundation to further examine the specific biological features of trisomy 21 neurons that affect cell-cell transmission of Alzheimer’s pathology using cerebral organoids.
My research interest is in understanding the genetic and functional links between Down Syndrome and Alzheimer’s Disease.
Assessment of specific biological features of trisomy 21 neurons, affecting cell-cell transmission of Alzheimer’s pathology using cerebral organoids.
Individuals with Down Syndrome (DS) have an increased risk of developing Alzheimer’s Disease (AD), but a delay in the age of onset of AD compared to what would be expected based on what we know about the genetics of AD. This suggests there are biological mechanisms in trisomy 21 (T21) brain cells (neurons) that can protect or alter how AD impacts the neurons, and how the disease spreads through the brain.
We have recently developed a human cellular model that starts from skin or hair follicle cells donated by a person with DS, whereby cells then get re-programmed into induced pluripotent stem cells, and these then driven to differentiate into brain cells. This allows us to model multiple aspects of AD pathology (amyloid plaques, aggregated Tau and neuronal cell death) in T21 cerebral organoids. The proposed project would use this model to examine how AD pathology spreads from neuron to neuron, and if this is different between T21 and control disomy 21 (D21) cells.
Understanding biological processes in neurons that delay AD onset in people with DS could be exploited as a protective/therapeutic strategy for AD, both for individuals with DS and for the general population.
