Prion-like transmission of human tau strains in the mouse brain - Nature
Mouse experiments show that Alzheimer’s disease and corticobasal degeneration tau filaments retain their distinct structures during templated seeding, supporting strain-specific tau propagation and disease modelling.

When we talk with AI researchers, one question comes up most frequently: do you have datasets focused on mutations at key protein positions? Until now, building libraries for that usually meant a lot of DNA synthesis. We developed HGT-DGR as a faster and cheaper way to make them.
