(2019) Full atomistic model of prion structure and conversion. These data inspire several new hypotheses to elucidate prion biology and design therapeutics for prion diseasesĬitation: Spagnolli G, Rigoli M, Orioli S, Sevillano AM, Faccioli P, Wille H, et al. This structure allowed us to model for the first time the process of prion propagation at high resolution. The model is stable and agrees with all available experimental data on PrP Sc. We have created a very detailed model of PrP Sc, which includes all its atoms, using computational techniques. Understanding the structure (“shape”) of the PrP Sc prion is critical to understand how it propagates. The scrapie isoform of the mammalian prion protein, PrP Sc, is the most notorious prion, and is responsible for deadly neurodegenerative diseases affecting humans, like Creutzfeldt-Jakob disease, and animals, such as bovine spongiform encephalopathy (“mad cow disease”) and chronic wasting disease affecting elk and deer in North America and, more recently, Europe). They consist of assemblies of misfolded proteins. Prions are unusual infectious pathogens that do not contain any nucleic acid. This study provides the most updated, experimentally-driven and physically-coherent model of PrP Sc, together with an unprecedented reconstruction of the mechanism underlying the self-catalytic propagation of prions. Importantly, the 4RβS arrangement allowed the first simulation of the sequence of events underlying PrP C conversion into PrP Sc. The stability of this new PrP Sc model, as assessed by Molecular Dynamics (MD) simulations, was found to be comparable to that of the prion forming domain of Het-s, a naturally-occurring β-solenoid. Here, we combined different experimental data and computational techniques to build the first physically-plausible, atomic resolution model of mouse PrP Sc, based on the 4RβS architecture. Recent cryo-electron microscopy (cryo-EM) and X-ray fiber-diffraction studies provided evidence that PrP Sc is structured as a 4-rung β-solenoid (4RβS). Similar folding models have also been proposed for PrP Sc, although none of these have been confirmed experimentally. Most aggregates of other misfolding-prone proteins are amyloids, often arranged in a Parallel-In-Register-β-Sheet (PIRIBS) or β-solenoid conformations. The first prion identified, the scrapie isoform (PrP Sc) of the cellular prion protein (PrP C), caused epidemic and epizootic episodes.
