Blood-Brain Barrier Models for Enhanced Brain Health Research The blood-brain barrier (BBB) model with ALUF (artificial lipid ultrafiltration) represents a cutting-edge approach to studying the selective permeability of the blood-brain barrier, a crucial defense mechanism that protects the brain from harmful substances in the bloodstream while allowing essential nutrients to pass through. The BBB model with ALUF is used to simulate and better understand this complex barrier's functioning under laboratory conditions. Visit - https://www.aluf.com/
