Until now, scientists have not known exactly how inflammation weakens the blood-brain barrier, allowing toxins and other molecules access to the brain. A new research report solves this mystery by showing that a molecule, called 'microRNA-155,' is responsible for cleaving epithelial cells to create microscopic gaps that let material through.
