Multiple Sclerosis: Researchers Are Recruiting for Genetic Studies
Multiple sclerosis is a disease in which the immune system in the body attacks the central nervous system. The immune system may actually be occurring in a way that the immune system itself is responding to antigens that occur normally. Antigens are proteins that cause the immune system to respond. MS affects various parts of the central nervous system, including the brain, spinal cord, and the optic nerves. It is still unknown as to whether MS is autoimmune or immune-mediated, but specialists all agree that there is some connection between MS and the body's immune system.
There are four different recognized types or courses of MS: Clinically isolated syndrome (CIS), relapsing-remitting MS (RRMS), primary progressive MS (PPMS), and secondary progressive MS (SPMS). The severity of each of the four types of MS can range anywhere between mild and severe.
Currently, researchers are looking to predict which people are at the greatest risk for MS by examining their genes.
