Patient-derived homogenates induce seeding in the pTau biosensor cell lines. a-c: A Tau (P301S) biosensor cell line underwent incubation with sarkosyl-insoluble homogenates from the temporal cortex of 1 non-AD/PART case and 1 AD case; a non-treated cell line served as a control. AD brain homogenates exhibited increased pTau seeding, indicated by an increase in green spots (indicated by white arrows), compared to the non-AD/PART case. d: After 48 h, the number of positive pTau spots/cells was automatically quantified, and the one-way ANOVA with Tukey’s multiple comparisons test revealed a significant difference (p < 0,0001) between the analyzed cases.
