Supplementary Figure 1: Tau pathology co-localizes with EX, but not with IN neurons in secondary affected regions in EC-tau mice.

(a-d) Representative images of MC1+ tau staining co-localized with TBR1+ and SATB2+ EX neurons, but not PVALB+, SST+ or CALB2+ IN neurons, in the PRH (a) and NC (b) of EC-tau mice at 22 months (n = 6 animals, 2 sections each animal), and in the PRH (c) and NC (d) of EC-tau mice at 30+ months (n = 5-6 animals, 2 sections each animal). Scale bar, 20 µm.
