**Molecular Mechanism and Rationale** The mitochondrial calcium uniporter (MCU) represents a critical nexus in cellular bioenergetics and calcium homeostasis, particularly in neurons with high metabolic demands such as layer II stellate neurons of the entorhinal cortex. These neurons exhibit distinctive electrophysiological properties, including high-frequency firing patterns and extensive dendritic arborizations that create extraordinary calcium handling requirements. The MCU complex, comprisi

**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
