7. Inflammation and damage to what part of the body causes MS symptoms?

8. What usually prevents immune cells from entering the brain in healthy individuals?
The blood-brain barrier
The immune-brain barrier
Immune cells are never near the brain
The blood-brain barrier is compromised in people with MS, which allows immune cells like B and T cells from circulating blood into the brain.
