Comparing 2 hypotheses side-by-side
Beyond serving as metabolic fuel, β-hydroxybutyrate (BHB) signals through hydroxycarboxylic acid receptor 2 (HCAR2/GPR109A) on astrocytes to suppress NF-κB activation and reduce neuroinflammation. The therapeutic window corresponds to a period when BHB levels decline sufficiently to lose receptor engagement but before glial activation becomes irreversible. Direct HCAR2 agonists (e.g., niacin, β-hydroxybutyrate prodrugs) could provide neuroprotection independent of metabolic fuel effects.
**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
