Independent: Researchers at Northwestern University in Chicago have been developing a nanoparticle to treat multiple sclerosis (MS) and other immune-related diseases. Unlike drugs that suppress the entire immune system and leave patients more susceptible to infections, nanoparticles target only the part of the immune system responsible for the particular disease being treated. In the trial, mice suffering from MS were injected with nanoparticles attached to myelin antigens, which stopped their immune systems from attacking the myelin sheath surrounding their nerve cells. “The beauty of this new technology is it can be used in many immune-related diseases,” said Stephen Miller, coauthor of the study published in Nature Biotechnology.
