BBB is a tight junction cell membrane distributed in blood vessels in the brain.
BBB acts as a barrier to prevent substances in the blood from entering brain tissue and protects the brain under normal circumstances.
However, if there is an abnormality in brain tissue and the drug needs to be delivered, the drug's delivery efficiency is hindered by BBB.
Therefore, the drug's BBB penetration rate makes or breaks treatment of brain disease.
Tech 3 is a technology that releases NO from blood vessels in the brain to temporarily open BBB and improves the delivery efficiency of existing treatments.
