Comparing 2 hypotheses side-by-side
**Molecular Mechanism and Rationale** The gut-brain axis represents a critical bidirectional communication pathway that fundamentally influences neuroinflammation and neurodegeneration through microbial metabolite signaling. Central to this mechanism is the tryptophan-aryl hydrocarbon receptor (AHR) axis, where beneficial commensal bacteria, particularly *Clostridium sporogenes*, *Peptostreptococcus russellii*, and certain *Lactobacillus* species, metabolize dietary tryptophan through the indol
**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
