Test whether pharmacological manipulation of M1:M23 AQP4 isoform ratio or modulation of orthogonal array of particles (OAPs) assembly can preserve physiological water transport and perivascular clearance while reducing pathological AQP4 clustering that may amplify autoantibody binding in NMOSD. Evidence indicates that M23 promotes large OAPs while M1 restricts array size, with M1/M23 ratios determining OAP composition; AQP4 OAPs are central to membrane organization and NMOSD antibody interaction
**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
