How Myelin Affects The Body 's Immune System Targets The Central Nervous System

Multiple sclerosis (MS) involves an autoimmune process that develops when a previous viral insult to the nervous system has occurred in a genetically susceptible individual. B lymphocytes, plasma cells, and activated T cells, along with proinflammatory cytokines, cause inflammation, oligodendrocyte injury and demyelination. Early inflammation and demyelination lead to irreversible axonal

Multiple Sclerosis (MS) is an autoimmune disease, in which the body's immune system attacks its own tissues. The disease destroys the myelin, which is the insulation that protects the nerve fibers in the spinal cord, and brain (Niino, 2008). When the myelin is damaged, the message that is traveling along that nerve may be slowed or blocked. Symptoms vary by patient, but often include: numbness or weakness in limbs, partial or complete loss of vision, lack of coordination or unsteady gait, slurred speech, fatigue, dizziness, and problems with bowel and bladder functions.

(National MS Society) (Mayo Clinic) Myelin is the fatty substance that surrounds and insulated the nerve fibers. (National MS Society) Multiple Sclerosis is also know to be an immune-mediated process that sends abnormal responses of the body’s immune system that is directed again the Central Nervous System (CNS). Myelin is compared to the insulation on electrical wires. (National Multiple Sclerosis Society) The Central Nervous System is made up of the optic nerves, brain and spinal cord. The exact antigen – or target that the immune cells are sensitized to attack remains unknown. (National Multiple Sclerosis Society) In Multiple Sclerosis immune system There is yet to be any reason as to what causes MS. Scientist believe the disease is triggered by but not yet identified by environmental factors in a person who is genetically predisposed to respond. (National MS Society) Some researchers say that it is an autoimmune disease. There is no cure for MS, but there are treatments that can help you recovery and minimize your attacks, and modify the diseases course. (Mayo Clinic)

Multiple sclerosis (MS) is an unpredictable, immune mediated disease of the central nervous system (CNS) (Definition of MS). This disease is estimated to affect more than 400,000 people in the United States alone, and about 2.5 million worldwide. In the United States, about 200 new cases of MS are discovered weekly (Pietrangelo, Anne and Higuera, Valencia) . In a healthy person, an insulation covering called myelin, coats the nerve fibers in the CNS (Article from mom). When one develops MS, the communication between their brain and other parts of his/her body is disrupted as “an abnormal immune-mediated response” attacks the myelin coating that encloses nerve fibers in the CNS. This causes a disturbance in communication between the CNS and

MS is characterized by the destruction of myelin, inflammation in the CNS and the formation of lesions in the CNS.

Multiple sclerosis, or MS, is a disease of the central nervous system. The central nervous system is made up of the brain and spinal cord. Both have nerve fibers that are wrapped in a myelin sheath. In MS, the myelin sheath becomes inflamed and gradually is destroyed. With the destruction of the myelin sheath comes an array of symptoms that may include numbness or tingling, balance problems, weakness, muscle spasms, and blurred vision.

Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system. MS affects approximately 3.0 million people globally, with about 300,000 cases in the United States. Twice as many women as men have MS. The average ages for onset of MS is 20-40 years. In MS, cells in the immune system attack and destroy myelin, the fatty tissue surrounding nerve cells (http://www.phylomed.com/MS.html). Scar tissue replaces the myelin, interfering with the transmission of nerve signals and leading to numbness, fatigue, spasticity, loss of muscle control, and various other debilitating symptoms. There are four broad theories

Multiple Sclerosis (MS) is an autoimmune disease that attacks the central nervous system. The myelinated nerve cells get attacked which results in scars and lesions that destroy the myelin sheath. The reason for the body attacking its own nerve cells is unknown. Many believe that the cause of MS is from a virus, a deficiency in Vitamin D, or genetics. Studies are being done to find out what is the real cause of MS.

Multiple Sclerosis (MS) a disease which the immune system attacks the protective sheath also known as the myelin that covers the nerves. Damages myelin disrupts the communication between the brain and the rest of the body. The nerves itself may weaken, process that is currently irreversible.

Multiple Sclerosis, commonly known as MS is an autoimmune disease of the central nervous system. Scientists have been studying MS since the 19th century. In MS, the body’s immune system produces cells and antibodies that attack myelin in your brain which is essential for the nerves in your brain and spinal cord to conduct electricity to perform its function. The attack on myelin results in vison loss, paralysis, numbness, muscle weakness, difficulty walking, stiffness, spasms, and bladder and bowel problems. MS has varying degrees of severity and affects people between the ages of 20-50, mostly women. Although there are treatments, there is no cause and cure yet.

Multiple Sclerosis is an inflammatory demyelinating neurodegenerative disorder of the central nervous system that has the potential to cause significant disability in those affected through the body's immune system attacking and destroying the myelin sheaths surrounding the axons. Myelin is rich in lipids and proteins that form layers around the nerve fibers and acts as insulation and protection. This damage to the myelin in the CNS, and to the actual nerve fibers, has the potential to block the transmission of nerve signals between the brain and spinal cord and also other parts of the body. This disruption of the nerve signals produces the primary symptoms of MS which then possibly lead to secondary and tertiary symptoms stemming from these

The following are found in a high percentage of those affected by MS, mainly during a relapsing-remitting of the disease, or they are persistent in chronic-progressive patients. Patients with MS have inflammation in their CNS as well as oligoclonal bands in their cerebrospinal fluid. What this means is that an immune system that is no longer efficient now prevents memory T-cells from becoming activated or entering the CNS and mediating much of the damage that is associated with MS, causing more health issues for those with MS. When the immune system no longer functions properly in these patients, they also become susceptible to viral diseases. There is also a theory that exposure to a certain virus may lead to a pathology in the immune system, which then results in MS, viral infections are known to provoke relapses of the disease, making a viral infection that leads to MS a plausible

Multiple sclerosis, or MS as it is more commonly referred, is an immune mediated disease that involves the body's own defense mechanism, specialized immune cells, that ultimately attacks the central nervous system. Specifically, the myelin protein that coats axons and forms an electrically insulating layer for quicker processing of the nervous system, is attacked by cytotoxic cells that have crossed into the CNS. In a healthy patient, the blood brain barrier cannot be crossed by cytotoxic cells and it is speculated that an environmental component or outside source mediates this crossing. When the myelin is attacked, it forms scars in the CNS, as multiple sclerosis literally translates to “many scars,” which is the direct result of the disease. The scars disrupt the normal nerve impulses that travel through the central nervous system, and can cause a variety of symptoms including loss of cognition, fatigue, or numbness in the body (Evidence).

Multiple sclerosis, also known as MS, is an autoimmune and inflammatory disease that is very painful for both the patient and care giver. In the disease, there is inflammation and neurodegeneration acting at the same time. There is currently no known primary cause of multiple sclerosis. The disease is however characterized by damaged fatty myelin sheaths around the axons of the brain and the spinal cord. Myelin is a mixture of proteins and phospholipids that protects many nerve fibers enabling speed at which impulses are conducted. It is pathologically characterized as the presence of glial scars all over in the central nervous system. The disease was discovered by the French neurologist Jean-Martin Charcot in 1868 when he examined the brain
