## **Molecular Mechanism and Rationale** The transcription factor A, mitochondrial (TFAM) serves as the master regulator of mitochondrial DNA (mtDNA) transcription and copy number maintenance, making it a critical determinant of cellular bioenergetic capacity. TFAM functions as a high-mobility group (HMG)-box transcription factor that binds to the heavy strand promoter (HSP1 and HSP2) and light strand promoter (LSP) regions of mtDNA, initiating transcription of the 13 protein-coding genes essen

**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
