Images were captured by Carl Zeiss confocal LSM700 and confocal Zeiss LSM 880 with Airyscan. The immunofluorescence-stained DAPI-positive cells in each image of asteroids were quantified by ImageJ by automated cell counting. The staining intensity in immunofluorescence-labeled asteroids were measured by ImageJ. The intensity of MC1, TOMA2, CP13, AT8, ThioS, and Fluoro Jade B were normalized by the corresponding Tuj1 intensity. Schematics were created with BioRender.com.
Statistical analyses and figures artwork were performed using GraphPad Prism version 9.00 for Windows with a two-sided α of 0.05. All group data are expressed as mean ± SEM. Column means were compared using one-way ANOVA with treatment as the independent variable. Group means were compared using two-way ANOVA with factors on oTau treatment and timepoints, respectively. When ANOVA showed a significant difference, pairwise comparisons between group means were examined by Tukey’s, Dunnett or uncorrected Fisher’s LSD multiple-comparison test. Significance was defined when P < 0.05. LDH assay data analysis was performed with a paired t test.
