The aquaporin-4 polarization rescue hypothesis proposes a sophisticated mechanistic framework linking tau pathology to glymphatic dysfunction through strain-specific disruption of astrocytic water channel organization. This hypothesis centers on the differential vulnerability of brainstem versus cortical astrocytes to 4R-tau strains and posits that targeted restoration of AQP4 polarity could serve as a therapeutic intervention to prevent characteristic aggregation patterns in neurodegenerative d

**Molecular Mechanism and Rationale** The senescence-associated secretory phenotype (SASP) represents a critical pathophysiological mechanism underlying age-related neurodegeneration through its disruption of the glymphatic clearance system. Senescent astrocytes, which accumulate progressively with aging and in neurodegenerative conditions, undergo a dramatic shift in their secretory profile, producing elevated levels of pro-inflammatory cytokines including tumor necrosis factor-alpha (TNF-α),
