Multiple sclerosis (MS) is a disease of both the immune system and the nervous system. The individual’s immune system attacks the protective coating encasing nerve cells. As a result, the transmission of nervous signals is impaired, which may result in mobility and cognitive issues. There is currently no cure, although medications exist to alleviate specific symptoms. Scientists are currently investigating whether blood stem cell transplants (bone marrow transplants) might be used to replace the faulty immune cells in individuals with MS. In this section you will find factsheets about MS, ongoing research into gene and cell-based therapies, and guidelines as to where you can look for support if you or a loved one are living with MS.
