The Central Nervous System

The human microbiota is composed of diverse forms of microorganisms that live on or in us and plays a crucial role in the health and development. Commensal species that reside in the intestine particularly influence host physiology at local and systemic levels. Multiple sclerosis (MS) is a debilitating autoimmune disorder of the central nervous system for which there is currently no cure. While the cause of MS is unknown, there is a growing body of evidence suggesting that the microbiota can play both pathogenic and protective roles in disease progression. In this review, we provide a brief overview, based on both animal and clinical studies, of the current understanding by which the microbiota may influence MS and discuss opportunities for therapeutic intervention that may alleviate the symptoms associated with this debilitating neuroimmunological disease.

Multiple Sclerosis Treatment

Multiple sclerosis (MS) is considered to be an autoimmune disease of the central nervous system that targets myelin but affects both white matter and gray matter. Multiple sclerosis is thought to be mediated by cells of the adaptive and innate immune systems. CD4+ T lymphocytes of the Th1 and Th17 subtypes are believed to be critical for the initiation of multiple sclerosis. Treatment with monoclonal antibodies that deplete B lymphocytes has proven that B cells are critical to relapse development in multiple sclerosis. While immunopathophysiology is clearly important in MS, whether multiple sclerosis is truly an autoimmune disorder and the target or targets of the autoimmunity remain unknown.

And Oxidative Stress

Multiple sclerosis (MS) exhibits many of the hallmarks of an inflammatory autoimmune disorder including breakdown of the blood-brain barrier (BBB), the recruitment of lymphocytes, microglia, and macrophages to lesion sites, the presence of multiple lesions, generally being more pronounced in the brain stem and spinal cord, the predominantly perivascular location of lesions, the temporal maturation of lesions from inflammation through demyelination, to gliosis and partial remyelination, and the presence of immunoglobulin in the central nervous system and cerebrospinal fluid. Lymphocytes activated in the periphery infiltrate the central nervous system to trigger a local immune response that ultimately damages myelin and axons. Pro-inflammatory cytokines amplify the inflammatory cascade by compromising the BBB, recruiting immune cells from the periphery, and activating resident microglia. inflammation-associated oxidative burst in activated microglia and macrophages plays an important role in the demyelination and free radical-mediated tissue injury in the pathogenesis of MS. The inflammatory environment in demyelinating lesions leads to the generation of oxygen- and nitrogen-free radicals as well as proinflammatory cytokines which contribute to the development and progression of the disease. Inflammation can lead to oxidative stress and vice versa. Thus, oxidative stress and inflammation are involved in a self-perpetuating cycle.

Stem Cells Transplantation

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system. Umbilical cord derived mesenchymal stem cells are immunosuppressive. We transplanted mesenchymal stem cells in a patient with refractory progressive MS, and the disease course was stabilized after the transplantation. We postulate that mesenchymal stem cells have a potent immunosuppressive effect in vivo.

Spectrum Disorders

Neuromyelitis optica (NMO), a chronic inflammatory, demyelinating autoimmune disorder of the central nervous system with a predilection for the optic nerves and spinal cord, has long been confused with classical multiple sclerosis. In this chapter, we review the important clinical and radiographic distinctions of NMO and NMO spectrum disorders, and summarize promising new concepts in pathophysiology and therapeutic approaches.

The Central Nervous System

Multiple sclerosis (MS) is the most common cause of nontraumatic disability in young adults. It is a chronic inflammatory demyelinating disease of the central nervous system. Traditionally, MS has been considered an autoimmune disorder consisting of myelin autoreactive T cells that drive an inflammatory process, leading to secondary macrophage recruitment and subsequent myelin destruction. However, accumulating data based on increasing numbers of probes that can be effectively applied to MS tissue have indicated that the events involved in the immunopathogenesis of MS may be more complicated.

Damage is caused to the myelin sheath surrounding nerves, thus impairing the conduction of impulses. The condition varies from a relapsing/remitting pattern (∼80% patients) to a progressive form that may be fatal within a few years. Nutritional considerations relate to:...

AbstractAcquired demyelinating syndromes (ADS) present with acute or subacute monofocal or polyfocal neurologic deficits localizing to the central nervous system. The clinical features of distinct ADS have been carefully characterized including optic neuritis, transverse myelitis, and acute disseminated encephalomyelitis. These disorders may all be monophasic disorders. Alternatively, optic neuritis, partial transverse myelitis, and acute disseminated encephalomyelitis may be first presentations of a relapsing or polyphasic neuroinflammatory disorder, such as multiple sclerosis or neuromyelitis optica. The clinical features of these disorders and the differential diagnosis are discussed in this article.
