In multiple sclerosis, the body’s immune system attacks and damages myelin, which is the insulating layer on nerves in the spinal cord, brain and optic nerve. Just as would happen with an electrical cord with compromised insulation, this causes the nerves to short-circuit and cease functioning properly. An international team of scientists, however, have recently reported success in the first phase of clinical trials in which MS victims’ immune systems were conditioned to become much more tolerant of myelin.
