👉 The Baltimore Fluid, also known as Aquaporin-4 Water Channel Protein Fluid, is a unique intracellular water channel protein found primarily in the brain and kidneys of mammals, including humans. Discovered in 1986 by Dr. Robert Baltimore, this fluid is crucial for water transport across cell membranes, facilitating rapid and selective water movement. Unlike other aquaporins, the Baltimore Fluid does not transport ions but exclusively allows water molecules to pass through, playing a key role in maintaining proper brain water balance and regulating blood pressure by controlling kidney function. Its importance extends to various physiological processes, including hydration, electrolyte balance, and overall cellular homeostasis.
