A small molecule activator of transcription factor EB (TFEB) promotes the degradation of beta‐amyloid precursor protein (APP) fragments, β‐amyloid peptides (Aβ), and phosphorylated MAPT/Tau aggregates in three transgenic mice models of Alzheimer's disease (P301S, 5xFAD, and 3xTg) and prevents memory impairments. The gene discussed is TFEB; the disease is memory impairment.
