Cell-Type-Specific TFEB Modulation Combined with Trehalose for Targeted Alzheimer's Disease Intervention
🧪 Overview
This hypothesis proposes that precise, neuron-specific TFEB modulation at optimal levels, combined with trehalose co-treatment, can restore lysosomal function in Alzheimer's disease while avoiding the detrimental effects of global TFEB activation. Building on the 'Goldilocks principle' that TFEB requires precise dosing to avoid toxicity, we will use neuron-specific promoters (such as CaMKII or synapsin) to drive moderate TFEB overexpression exclusively in excitatory neurons of AD-affected brain regions. This targeted approach circumvents the neuroinflammatory and microglial activation issues associated with global TFEB upregulation, while avoiding the α-synuclein-related APP processing defects seen with non-specific overexpression. Trehalose will be administered as a complementary TFEB-independent lysosomal enhancer, providing additive benefits through its chemical chaperone properties and alternative autophagy stimulation pathways. This dual intervention targets the fundamental cellular waste management deficits underlying amyloid-beta and tau accumulation at synapses, where lysosomal dysfunction is most critical for cognitive decline.
