AQP4: From Water Channel to a Potential Drug Target in Neurological Diseases
Aquaporins (AQPs) are best known as membrane channels that transport water. As research has advanced, however, their biological significance has expanded far beyond basic water transport to include cerebral edema, autoimmunity, brain fluid clearance, and neurodegenerative diseases. Among the AQP family, aquaporin-4 (AQP4) has attracted particular attention because of its distinctive distribution and complex regulation in the central nervous system (CNS).
