The immune system is composed of organs, tissues, cells, and chemical messengers that interact to protect the body from external invaders and its own internally altered cells. The chemical messengers arecytokines which are secreted by cells of the immune system that direct immune cellular interactions. Lymphocytes (leukocytes that are categorized as either B cells or T cells) secrete lymphokines.Approximately 2.5 million people worldwide are afflicted with MS , a chronic neuroinflammatory disease of the brain and medulla spinalis that's a standard explanation for serious physical disability in young adults1, especially women. MS poses a serious personal and socioeconomic burden: the typical age of disease onset is 30 years — a time that's decisive for work and birth control.Two decades of clinical experience with the immunomodulatory treatment of MS points to distinct immunological pathways that drive disease relapses and progression. Although the immunomodulatory drugs reduce the frequency of relapses, the trade-off of efficacy may be a range of side effects, and therefore the long-standing drugs approved for MS don't ultimately halt neurodegeneration.
