Antigens are generally proteins that stimulate an immune response.
Basically, the immune system in the body attacks the nerves.
The second theory is that MS is caused by environmental factors. Studies have shown that MS occurs more in places that are farther from the equator. Some scientists believe that this proximity from the equator actually has something to do with Vitamin D. Vitamin D is produced by the body. In regions that are further from the equator, the sunlight is more filtered, thereby reducing the amount of vitamin D that is produced by the body.
Studies have also shown that people who are born in a part of the world with a high risk of MS, who therefore move to a new area, acquire the risk in the new area. This suggests that there is some...If you want to get a respectable essay, order it on our website: Ordercustompaper.com
