Furthermore, recent studies have shown that clearance of senescent cells had beneficial effects in mouse models of AD and tau‐dependent neurodegenerative diseases (Bussian et al., 2018; Musi et al., 2018; Zhang et al., 2019), PD (Chinta et al., 2018), PPMS (Nicaise et al., 2019), and ALS (Trias et al., 2019). Here, MAPT is linked to Parkinson disease.
