Blood Brain Barrier Permeability. The blood brain barrier (BBB) is a physical barrier formed by the arrangement of endothelial cells and tight junctions that line the capillaries which supply blood to the brain. It is a highly selective barrier that restricts the movement of molecules from the blood across to the brain.

Modulating the permeability of a physiological barrier with an agent that modulates tyrosine phosphorylation
InactiveUS6312686B1Reduce penetrationStrict controlHeavy metal active ingredientsNervous disorderBlood brain barrier permeabilityBarrier permeability
Permeability of the blood-brain barrier and other physiological barriers can be modulated by the degree of tyrosine phosphorylation of proteins. Agents which promote tyrosine protein dephosphorylation reduce the permeability of the blood-brain barrier and those which promote phosphorylation increase permeability. Increasing blood-brain barrier permeability is useful in delivering drugs having a desired effect upon the central nervous system; decreasing blood-brain barrier permeability and other physiological barrier permeability is useful in preventing undesired compounds reaching the CNS and in certain clinical conditions.
