**Molecular Mechanism and Rationale** The lysine demethylase 6A (KDM6A), also known as UTX (Ubiquitously Transcribed Tetratricopeptide Repeat, X chromosome), represents a critical epigenetic regulator that catalyzes the removal of repressive histone H3 lysine 27 trimethylation (H3K27me3) marks through its Jumonji C (JmjC) domain-containing demethylase activity. This chromatin-modifying enzyme functions as part of the larger COMPASS-like complexes and operates in direct opposition to the Polycom

**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
