## Molecular Mechanism and Rationale The mPTP-mediated mtDNA release pathway operates through calcium-dependent conformational changes in cyclophilin D (PPIF), which regulates pore formation at the inner mitochondrial membrane in association with the adenine nucleotide translocator and voltage-dependent anion channel. Upon pathological calcium accumulation, cyclophilin D facilitates mPTP opening, leading to mitochondrial matrix swelling that mechanically ruptures the inner membrane and releases

**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
