The second objective aims at clarifying the basis of prion neurotoxicity and will be developed along two alleys: (a) we will uncover the molecular basis of spongiosis (the neuronal vacuolation characteristic of prion diseases), which we suspect to be a main driver of pathology, and (b) we will perform CRISPR-based synthetic lethality screens to identify genes that become essential to prion-infected cell lines (which do not experience prion toxicity) and may not be expressed by neurons.
