Comparing 2 hypotheses side-by-side
**Molecular Mechanism and Rationale** The gut-brain axis represents a critical bidirectional communication pathway that has emerged as a central player in neurodegenerative disease pathogenesis, particularly in α-synucleinopathies such as Parkinson's disease. The molecular foundation of this hypothesis centers on the compromised intestinal barrier integrity mediated by dysbiotic microbial communities and their direct impact on α-synuclein pathology propagation. The intestinal epithelial barrier
**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
