**Molecular Mechanism and Rationale**
The aquaporin-4 (AQP4) water channel represents a critical component of brain homeostasis, with its proper polarization at astrocytic perivascular end-feet serving as the primary driving force for cerebrospinal fluid-interstitial fluid exchange through the glymphatic system. Under physiological conditions, AQP4 is anchored to the perivascular membrane through a complex involving dystrophin (Dp71), α-syntrophin, and dystrobrevin, collectively forming the dys
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
