Pharmacologically boosting programmed stop-codon readthrough of AQP4 to increase the AQP4X/AQP4ex isoform could restore impaired perivascular clearance in neurodegeneration. AQP4X contains a unique C-terminal sequence that enables its preferential localization to astrocytic perivascular endfeet, where AQP4ex is necessary for CNS perivascular AQP4 anchoring in mice. Supporting this approach, AQP4X-specific knockout impairs perivascular AQP4 localization and reduces amyloid-β clearance, and CSF AQ
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
