MS is considered to be an autoimmune disorder. I believe that all autoimmune disorders are a result of a virus (not bacteria) that has invaded your body for an extended amount of time giving it a chance to cross a barrier and manage to mimic specific cells, tissues, and/or organs in our body. In the case of MS, I believe some sort of virus crosses the blood brain barrier to enter the central nervous system. Our immune system is aware of it's presence and in it's attempt to destroy the virus, our nerve cells become collateral damage. Collateral damage is defined as "[the] unintentional damage or incidental damage affecting facilities, equipment, or personnel, occurring as a result of military actions directed against targeted enemy forces or facilities. Such damage can occur to friendly, neutral, and even enemy forces. An autoimmune disorder is caused by the body producing an inappropriate immune response against its own tissues. Sometimes the immune system will cease to recognize one or more of the body's normal constituents as "self" and will create autoantibodies – antibodies that attack its own cells, tissues, and/or organs. This causes inflammation and damage and it leads to autoimmune disorders. In the case of MS, RA (Rheumatoid Arthritis), Chron's disease and other autoimmune diseases, our bodies are being attacked by friendly fire (immune system) in an attempt to get to the enemy (virus).
MS therapies are designed to weaken the immune system or modify the disease. Tysabri, my current choice of therapy, prevents white blood cells from crossing the blood brain barrier where they attack nerve cells. This helps to slow the progression of MS. The downside to this gives the JC virus an opportunity to cross the blood brain barrier as well and cause worse damage than the white blood cells. This causes a rare infection of the brain called PML (Primary Multifocal Leukoecephalopathy) which I have written about in some of my past postings. Tysabri is a bit of a double edged sword but a risk that I am willing to take until a cure for MS has been found. That is why I am so passionate about sharing my world with the world. I believe a cure for MS can and will be found and the more awareness we raise about MS, the better off we will be in creating a world free of MS.
The human body is a magnificent wonder of many systems designed to collaborate and work together for the common good. Like soldiers in the military the cells in our body do their best to protect human life. But as we know, nothing or no one is perfect except God who knows the plans that He has for us all. Whether we have MS, Cancer, ALS or any other disease of the body, put all your trust in God, who causes ALL things to work together for the good of those who love Him.
