Neuronal degeneration, or the death of neurons, is a critical aspect of neurodegenerative diseases like Alzheimer’s disease (AD). However, the mechanisms leading to this neuronal cell loss and how this process is controlled are not well understood. Our laboratory has generated an innovative chimeric model for AD. In this model, transplanted stem cell-derived human neurons recapitulate all neuropathological features of AD, providing the first in vivo model with tau pathology, neuronal tangles and granulovacuolar neurodegeneration. The new phospho-tau biomarkers can be measured in the blood of the animal models. These human neurons degenerate by the necroptosis pathway, and this observation was validated using human post-mortem AD brains. We have used this model to perform a CRISPR/CAS9 screen to delete genes in the human neurons. Neurons that can survive better because of the deleted gene will be more resilient and survive in our transplantation model. By deep sequencing, we can identify the genes that provide such an advantage. We have finalized such a screen and identified more than 10 interesting guide RNAs against kinases that appear to protect the neurons against necroptosis. In the current project, we aim to confirm these findings. Further, we will investigate and validate those kinases confirmed in AD pathology to explore whether they affect tau and necrosome pathology, and whether they can be used as drug candidates for the downstream pathways in AD. Such drugs are essential to complement amyloid beta therapies, which slow down but do not stop the disease process.
