**Molecular Mechanism and Rationale**
The molecular foundation of AQP4-mediated potassium spatial buffering involves a sophisticated tripartite complex comprising aquaporin-4 (AQP4), inwardly rectifying potassium channel Kir4.1 (KCNJ10), and the Na+/K+-ATPase alpha-2 subunit (ATP1A2). This macromolecular assembly, primarily localized to astrocyte endfeet at the blood-brain barrier and perivascular spaces, orchestrates the rapid clearance of extracellular K+ ions following neuronal depolarizatio
## 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
