Selectively modulate pathological AQP4 signaling or localization in substantia nigra astrocytes to reduce IL-1β/TNF-α-driven neuroinflammation while preserving glymphatic α-synuclein clearance, without complete AQP4 channel deletion. This approach addresses evidence that AQP4 participates in astrocyte-microglia communication and neuroinflammatory responses in experimental PD models (PMID 26774050). Because AQP4 deletion itself causes inflammation—complicating interpretation of AQP4-targeted appr
**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
Below are 7 therapeutic/mechanistic hypotheses for translating AQP4 biology into CNS-disorder interventions, with emphasis on Alzheimer’s disease, proteinopathies, edema/injury, and AQP4-IgG autoimmun...
