Glucose Transport Brain

Meaning

Glucose Transport in the Brain is the highly regulated physiological process by which glucose, the primary energy source for the central nervous system, is moved across the blood-brain barrier and into the neurons and glial cells. This transport is mediated by specialized carrier proteins, predominantly GLUT1 and GLUT3, ensuring a continuous and stable supply of fuel regardless of peripheral blood glucose fluctuations. Clinical assessment of this transport mechanism is crucial, as impaired brain glucose uptake is a hallmark of metabolic dysfunction that can severely compromise cognitive function.
