Our bodies expend countless amounts of energy to fight and defend against harmful diseases. Diseases come in many shapes and sizes and significantly affect our body's systems. One of the most important systems in our body is the nervous system. The nervous system is made up of a complex network of neurons that allows our body to take in information from the outside world, integrate and perceive this information. In addition, the nervous system allows us to act through motor control. Fundamentally, the nervous system is essential to our understanding and ability to interact with the world. Multiple sclerosis (MS) is a major disease that adversely affects the nervous system. This debilitating demyelinating disease attacks the human body's primary method of transmitting and communicating information, through inflammation of the central nervous system (CNS) of the brain and spinal cord. Normally, neurons in the CNS are insulated by a substance called myelin, which helps action potentials spread. These myelin sheaths are attacked by the body's immune system. This leads to degeneration of essential bodily functions such as walking, breathing and even thinking. We believe that the nervous system is one of the most important systems in our body. It not only controls our sensory, motor, and autonomic responses to the environment, but it is also arguably the system that makes us human. We were fascinated that a simple change in the myelination of cells could have such a profound effect on the body as a whole. Additionally, we have also had personal experiences with people who have unfortunately been diagnosed with MS. MS is a unique disease based on its etiology, which causes a... middle of paper ......acerbations of symptoms. Current research focuses on the differentiation capacity of mesenchymal stem cells which could potentially be used for immunomodulatory effects (Hoogduijn, 2010). However, there are many controversies associated with stem cell research. Additionally, researchers are exploring gene therapy possibilities by looking at “susceptibility genes,” or genes in an individual that increase the risk of developing MS. In this way, these sensitive genes can be studied in more detail and used as therapeutic targets. (NINDS, 2013; Mowry, 2013). One way to advance our knowledge and understanding of MS is through continued research based on current understanding of the disease. Many hope that more information about MS will be researched so that one day, even when a person is diagnosed with MS, the consequences are not devastating or life-threatening..
