**Background and Rationale**
The cellular quality control system represents one of the most critical determinants of neuronal survival and longevity. Among the key players in this system, the transcription factor EB (TFEB) has emerged as a master regulator of lysosomal biogenesis and autophagy, orchestrating what is increasingly recognized as the mitochondrial-lysosomal axis. TFEB belongs to the microphthalmia-associated transcription factor (MiTF) family and serves as the principal coordinator
## Cell-Type Specific TFEB Modulation
### Mechanistic Hypothesis Overview
The "Cell-Type Specific TFEB Modulation" hypothesis proposes that the transcription factor EB (TFEB) — the master regulator of autophagy and lysosomal biogenesis — is a high-value therapeutic target for Alzheimer's disease, and that cell-type specific TFEB activation can simultaneously enhance Aβ clearance, tau turnover, and mitochondrial quality control without the toxicity associated with non-selective TFEB activation.
