Currently, there is no efficient method to permanently bypass the blood-brain barrier.  Now, researchers at Harvard Medical School and Boston University have successfully shown neuroprotection in a Parkinson’s mouse model using a new technique, known as nasal mucosal grafting, to deliver drugs across … Continue reading New technique bypasses the blood-brain barrier to deliver neuroprotection.
