Figure Legend Snippet: Silencing and inhibition of Usp7 and Usp10 reduces seeded Tau aggregation induced by AD-TAU seeds in wildtype CTX. ( A ) Cortical neurons isolated from wildtype mouse embryos were incubated at DIV 1 with 1 µM individual siRNA Usp7 #13, Usp10 #14, smartpool Mapt (siMapt) or non-targeting control (neg. con). At DIV 7, cultures were treated with 1 µg/µL AD-TAU seeds and harvested at DIV 15 to measure seeded Tau aggregation by the mouse Tau aggregation assay. ( B ) Cortical neurons isolated from wildtype mouse embryos were incubated at DIV 7 with 1 µg/µL AD-TAU seeds and at DIV 8 incubated with the indicated concentrations of FT671, Spautin-1, or DMSO and harvested at DIV 15 to measure seeded Tau aggregation by the mouse Tau aggregation assay. IC 50 values of 410 nM for FT671 and of 590 nM for Spautin-1 were calculated. Data are presented as percentage seeded mouse Tau aggregation normalized to total protein, mean ± SD from 5 wells representative from 3 independent experiments. Brown–Forsythe and Welch ANOVA with Dunnett’s T3 post hoc test was performed; asterisks indicate significance (* p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001).

Figure Legend Snippet: USP7 and USP10 inhibitors reduce seeded TAU aggregation and increase polyubiquitination of TAU inclusions in CTX from rTg4510 mice. Cortical neurons isolated from rTg4510 mouse embryos were incubated at DIV 7 with 2 ng/µL S1p or P3 TAU seeds and at DIV 8 incubated with the indicated concentrations of FT671, GNE-6044, Spautin-1 or DMSO and harvested at DIV 15 to measure seeded TAU aggregation by the TAU aggregation assay ( A ) presented as percentage seeded TAU aggregation normalized to total protein, mean ± SD from 5 wells, representative from 3 independent experiments and by immunocytochemistry and quantifications of pS422-TAU ( B ) and polyubiquitination by P4D1 ( C ) immunoreactivity shown as Spot Total Intensity/healthy nuclei count as mean ± SD from 5 wells representative from 3 independent experiments. Following IC 50 values were calculated for FT671, GNE-6640, and Spautin-1, respectively: ( A ) 400–440 nM, 680–730 nM, and 560–650 nM; ( B ) 400–540 nM, 780–840 nM, and 600–690 nM; ( C ) 460–510 nM, 740–780 nM, and 580–640 nM. ( D ) P4D1 polyubiquitin and pS422-TAU immunoreactivity of P3-induced seeded TAU inclusions is presented as Spot Total Intensity/Spot as mean ± SD from 5 wells representative from 3 independent experiments. Brown–Forsythe and Welch ANOVA with Dunnett’s T3 post hoc test was conducted; asterisks indicate significance (* p < 0.05, ** p < 0.01, *** p < 0.001).

Figure Legend Snippet: Silencing and inhibition of Usp7 and Usp10 reduces seeded TAU aggregation in OHSCs from rTg4510 mice. ( A , B ) Organotypic hippocampal slice cultures (OHSCs) isolated from rTg4510 mouse pups were treated at DIV 0 with 1 µM siRNA Usp7 #13 or Usp10 #14 or non-targeting control (neg. control). At DIV 3, slices were incubated with 2 ng/µL S1p or P3 TAU seeds per slice. ( C , D ) OHSCs isolated from rTg4510 mouse pups were incubated with the indicated concentrations of FT671, GNE-6044, Spautin-1 or DMSO 3 h before addition of 2 ng/µL S1p or P3 TAU seeds per slice at DIV 3. ( A , D ) Slices were methanol-fixed at DIV 8 and processed for AT8 and pS422-TAU immunocytochemistry to measure seeded TAU aggregation. Representative confocal images (5× objective) of nuclei stained with Hoechst (in gray) and P3-induced seeded TAU aggregation detected with AT8 (in green) and pS422-TAU (in red) immunoreactivity from 3 independent experiments. The scale bar corresponds to 500 µm ( A , C ). Quantifications of AT8 immunoreactivity from S1p and P3 seeded slices are shown as total AT8 intensity as mean ± SD from 6 to 10 individual slices presented as circles ( B , D ). Brown–Forsythe and Welch ANOVA with Dunnett’s T3 post hoc test was performed; asterisks indicate significance (** p < 0.01, *** p < 0.001, **** p < 0.0001).
