b'Th17, and Th2. The Th1 and Th17 cells are said to be inammatory in nature and are relatively overrepresented in people with MS. During a relapse, Th1 and Th17 cells may be moving across the blood-brain barrier more easily, resulting in damage to myelin and nerve bers (axons). B-cells are immune cells that have two major roles in inammation. B-cells can become plasma cells, which produce antibodies. Antibodies are crucial in protecting us from foreign invaders like bacteria. They can also be problematic in autoimmune diseases such as MS, where they create autoreactive antibodies (antibodies which falsely identify your own cells as a danger). B-cells also regulate T-cell production and can trigger proinammatory cytokines.Finally, macrophages also play a role in the inammatory damage of an MS relapse. Macrophage comes from the Greek words makro meaning big and phagein meaning to eat. So, macrophages are big eaters. Think of them as gobbling up bacteria or other undesirable things in your body. Again, this normally helpful cell can be turned against healthy tissue, such as myelin, in the setting of an autoimmune disease. Supporting Immune FunctionIf your immune system is on the attack, why would you want to take action that improves immune function? Its important to understand we are not suggesting using immune boosters to increase or stimulate your bodys immune response. Rather, supporting your immune system means giving your body what it needs to have a healthy and balanced immune response. This will not only help your immune system perform its intended function by protecting you from viruses and bacteria, but can help increase the immune systems anti-inammatory actions. This can help regulate your immune health. Immune BoosterA supplement thats meantNot recommended for people to increase the activity ofwith MS the immune system (such as echinacea or astragalus)Immune Support A nutrient needed for theStrongly recommended for immune system to function people with MS optimally, or an action that helps regulate the immune systemImmune supports fall in five major areas: nutrition, exercise, sleep, stress management, and medication. Lets examine each of these areas and how it supports your immune health.Diet and Nutrition Every cell in your body needs nutrients to function, including your immune cells. New immune cells cannot be created without proteins and essential fatty acids. Certain vitamins are essential for the growth of immune cells; others play a role in regulating immune response. Minerals such as iron and selenium contribute to 3'
