Evidences path(MESH:Tauopathies) to p(MGI:Tfeb)

In the rTg4510 mouse model of tauopathy (Ramsden et al., 2005; SantaCruz et al., 2005), gene set enrichment analysis (GSEA) of microarray data revealed a similar enrichment of TFEB’s tran- scriptional profile when comparing 4-mo-old transgenic mice with widespread NFTs to wild-type mice, indicating TFEB’s activation with tau pathology (Fig. 1 F).

Examining the protein levels in another tauopathy mouse model, hippocampal lysates from PS19 mice (Yoshiyama et al., 2007) at 10 mo of age showed increases in TFEB and lysosomal proteins LAMP1 and CTSD com- pared with wild-type mice (Fig. S1, G and H).

Overall, these results show that astroglial TFEB overexpression reduces tau pathology and gliosis in the hippocampus of PS19 tauopathy mice.
