[Mechanisms of nutrient and drug transfer through the blood-brain barrier and their pharmacological changes].


The blood-brain barrier is formed by the endothelial cells of the brain capillaries. Its primary characteristic is the impermeability of the capillary wall due to the presence of complex tight junctions and a low endocytic activity. Essential nutrients are delivered to the brain by selective transport mechanisms, such as glucose transporter and a variety of… (More)
