## Molecular Mechanism and Rationale The 26S proteasome represents the primary degradation machinery for misfolded and damaged proteins in eukaryotic cells, comprising a 20S catalytic core particle flanked by two 19S regulatory particles. The PSMC (Proteasome 26S Subunit, ATPase) gene family encodes six distinct ATPase subunits (PSMC1-6) that form the base of the 19S regulatory particle, serving as the molecular motors that unfold substrate proteins and translocate them into the catalytic chamb

**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
