MAPT and Alzheimer disease: AD patients’ brains showed colocalization of BRCA1 with tau in NFTs and neuropil threads (Figure 1A–D, Figure 2A, and Figure A3), and slight cytoplasmic AT8 positivity observed in the NC patients’ brains in the entorhinal cortex and hippocampal CA1 did not show colocalization of BRCA1 (Figure 1E,F and Figure 2B) as previously described [7,8].
