Human Neuron Model Better for Alzheimer’s Drug Development

Although considerable effort has been expended developing drug candidates for Alzheimer disease, none have yet succeeded owing to the lack of efficacy or to safety concerns. One potential shortcoming of current approaches to Alzheimer disease drug discovery and development is that they rely primarily on transformed cell lines and animal
models that substantially overexpress wild-type or mutant proteins.

It is possible that drug development failures thus far are caused in part by the limits of these approaches, which do
not accurately reveal how drug candidates will behave in naive human neuronal cells.
