## Multiplexed Base Editing for Simultaneous Neuroprotective Gene Activation ### Mechanistic Hypothesis Overview The "Multiplexed Base Editing for Simultaneous Neuroprotective Gene Activation" hypothesis proposes that base editing technology — which enables precise single-nucleotide changes without double-strand DNA breaks — can be used to simultaneously activate multiple neuroprotective gene programs in neurons and glia affected in Alzheimer's disease. The central claim is that rather than co

**SASP-Mediated Complement Cascade Amplification in Alzheimer's Disease** **Overview: Senescence, Inflammation, and Synaptic Loss** Cellular senescence—a state of irreversible growth arrest accompanied by a pro-inflammatory secretome—accumulates dramatically with age and in Alzheimer's disease. Senescent astrocytes and microglia secrete the senescence-associated secretory phenotype (SASP), a cocktail of cytokines, chemokines, proteases, and critically, complement cascade initiators including C
