Target the breakdown of communication between brain vascular cells and glial populations, particularly pericytes and astrocytes that maintain the blood-brain barrier. These cells show coordinated vulnerability patterns that compromise brain clearance mechanisms and nutrient delivery.

**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
