H63D HFE causes prolonged endoplasmic reticulum stress (PMID:21349849), which paradoxically triggers the REDD1-autophagy axis as a compensatory protective mechanism. Iron chelation may exacerbate ER stress, overwhelming the protective autophagy pathway. Combining ER stress reducers with autophagy enhancers will synergistically protect H63D neurons.

**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
