Answer:
--Block immune cells from crossing the blood brain barrier.
--Stimulate the regeneration of myelin.
Explanation:
Multiple sclerosis or shortly known as MS is an unpredictable disease caused in the humans. Multiple sclerosis affects the central nervous system of our brain which causes the disruption in the flow of the information within our brain, and between our brain and the body.
It is a very rare disease.

Multiple sclerosis can also be prevented by stimulating the myelin to regenerate.

Once these populations adapt to the environment, speciation rapidly occurs.
