Overview

TFEB (Transcription Factor EB) is a member of the MITF/TFE family of transcription factors and serves as a master regulator of lysosomal biogenesis and [autophagy](/entities/autophagy). TFEB controls the cellular degradative capacity by coordinating the expression of genes involved in autophagy, lysosomal function, and lipid metabolism.

In the context of neurodegeneration, TFEB has emerged as a critical therapeutic target for Alzheimer's Disease, Parkinson's Disease, and lysosomal storage disorders. TFEB activity is regulated by mTORC1-mediated phosphorylation, which controls its subcellular localization and transcriptional activity. Dysregulation of TFEB contributes to impaired protein clearance and accumulation of toxic aggregates in neurodegenerative diseases.

Function

TFEB (Transcription Factor EB) is a master regulator of lysosomal biogenesis and autophagy. It belongs to the MITF/TFE family of basic helix-loop-helix leucine zipper transcription factors. TFEB controls the expression of genes involved in autophagy (including LC3, ATG proteins), lysosomal function (including cathepsins, LAMP proteins), and lipid metabolism[@tfeb2019].

TFEB activity is regulated by phosphorylation through mTORC1. Under nutrient-rich conditions, TFEB is phosphorylated and retained in the cytoplasm. Upon starvation or mTORC1 inhibition, TFEB translocates to the nucleus where it activates its target genes. This makes TFEB a key integrator of cellular energy status and autophagy[@tfeb2020].

Disease Associations

Alzheimer's Disease

TFEB activation promotes clearance of [amyloid-beta](/proteins/amyloid-beta) plaques through enhanced autophagy. In AD models, TFEB overexpression reduces amyloid burden and improves cognitive function. TFEB activity is impaired in AD brain, contributing to defective autophagy and protein aggregate accumulation. TFEB is considered a therapeutic target for AD[@tfeb2018].

Parkinson's Disease

TFEB-mediated autophagy is crucial for clearing [α-synuclein](/proteins/alpha-synuclein) aggregates in PD. TFEB activation enhances the clearance of toxic protein aggregates and protects dopaminergic [neurons](/entities/neurons). Impaired TFEB activity contributes to α-synuclein accumulation in PD models. TFEB activators are being explored as PD therapeutics[@tfebmediated2019].

Lysosomal Storage Disorders

TFEB is a key therapeutic target for lysosomal storage disorders (LSDs). TFEB overexpression or activation can enhance lysosomal biogenesis and partially compensate for deficient lysosomal enzyme activity. This approach has shown promise in models of Gaucher disease, Pompe disease, and other LSDs[@small2021].

Expression

TFEB is ubiquitously expressed with high expression in tissues with high lysosomal activity, including liver, kidney, and brain. In the brain, TFEB is expressed in neurons and glial cells. Under basal conditions, TFEB localizes to the cytoplasm; upon autophagy induction, it translocates to the nucleus. TFEB expression in neurons is particularly important for maintaining protein homeostasis through autophagy[@tfeb2017].
