Using advanced imaging to observe the early stages of nerve damage in mice with MS, scientists in the US believe they have found an important early trigger for the disease: the leakage of a clotting protein across the blood-brain barrier that activates an immune response and results in a toxic environment that damages nerve cells. Through genetic modification, they also found a way to stop the protein triggering the immune response without impairing its ability to clot blood.
