Parkinson's disease is characterized by the accumulation of misfolded alpha-synuclein protein aggregates (Lewy bodies) in dopaminergic neurons of the substantia nigra, leading to progressive motor dysfunction and neuronal death. This hypothesis proposes that pharmacological or genetic activation of TFEB (Transcription Factor EB) can restore lysosomal biogenesis and enhance alpha-synuclein clearance specifically in Parkinson's disease-affected brain regions. TFEB dysfunction and impaired autophag
A9 dopaminergic neurons uniquely co-express TFEB and TFE3 at high levels, with TFE3 serving as a compensatory backup transcription factor for TFEB under lysosomal stress. In GBA1 deficiency, TFEB activation initially upregulates the CLEAR network to restore lysosomal biogenesis. However, in these neurons, this compensatory response fails because the newly synthesized LAMP2A protein cannot properly integrate into lysosomal membranes due to a concurrent defect in VPS35-mediated trafficking.
