Tau immunization prevents phospho-tau histopathology. (AD) PHF1 immunostaining revealed extensive tau pathology in the hippocampus (A: 5X objective, B: 20X objective) of 3xTg mice, that was greatly reduced in immunized mice (C,D). (EH) Only background staining was seen in the wt mice. (IK) Quantitative analysis of the PHF1 staining revealed significant reduction in tau aggregates in the combined group (I: 74%, p = 0.0008) as well as in males (J: 68%, p = 0.0437) and females (K: 78%, p = 0.0120) analyzed separately. Scale bar: 250 μm (A), 125 µm (B). *p < 0.05; ***p < 0.001 compared to 3xTg control. See text for exact p-values.
