IMPRiND partners UOXF and CNRS have now come up with a working laboratory model. They used induced pluripotent stem cells (iPSC) derived from both healthy subjects and patients with the alpha-synuclein gene defects to generate human dopaminergic neurons that are primarily affected in Parkinson’s disease. They found a way of ‘amplifying’ in a fairly pure form, the main constituent, called fibril, of alpha-synuclein clumps directly from post-mortem Parkinson’s brains. When they added these brain-derived fibrils onto the human dopaminergic neurons, they successfully triggered the aggregation of alpha-synuclein inside the cells and observed progressive neuronal loss.
A great IMPRiND achievement: Nature Comm. paper on α-synuclein strain effects in iPSC-dopaminergic neurons.
