Intrathecal antibody production is a hallmark of multiple sclerosis and humoral immunity is thought to play an important role in the inflammatory response and development of demyelinated lesions. The presence of lymphoid follicle-like structures in the cerebral meninges of some multiple sclerosis patients indicates that B-cell maturation can be sustained locally within the CNS and contribute to...

Multiple sclerosis is a chronic inflammatory disease of the central nervous system, associated with demyelination and neurodegeneration. The mechanisms of tissue injury are poorly understood, but recent data suggest that mitochondrial injury may play an important role in this process. Mitochondrial injury can be triggered by reactive oxygen and nitric oxide species, and we recently provided evi...

Multiple sclerosis is an inflammatory demyelinating disease of the central nervous system and a leading cause of neurological disability. The complex immunopathology and variable disease course of multiple sclerosis have limited effective treatment of all patients. Altering the metabolism of immune cells may be an attractive strategy to modify their function during autoimmunity. We examined the...

Multiple sclerosis is characterized by demyelination and chronic inflammation of the central nervous system. Extensive studies in the animal model experimental autoimmune encephalomyelitis have suggested that multiple sclerosis is an autoimmune disorder mediated by myelin-specific CD4 T cells secreting T helper type 1 cytokines and tumor necrosis factor alpha. This concept has been widely used ...

This investigation was conducted to determine whether or not plasma galactosyl ceramides were elevated in patients with stroke and multiple sclerosis, and to determine glycosyl ceramide concentrations in older, normal subjects. It was hypothesized that central nervous system destruction, like that which occurs in stroke or in the demyelination characteristic of multiple sclerosis, might be refl...

Multiple sclerosis is a chronic demyelinating disease of the central nervous system. Tumor-like manifestation of multiple sclerosis is one of the rare clinical variants and it is frequently misdiagnosed. This is a report on a 45-year-old man who presented with right-sided hemiparesis. Initial computed tomography and magnetic resonance imaging studies of the brain revealed a large hyperintense s...

Recent studies suggest that increased T-cell and autoantibody reactivity to lipids may be present in the autoimmune demyelinating disease multiple sclerosis. To perform large-scale multiplex analysis of antibody responses to lipids in multiple sclerosis, we developed microarrays composed of lipids present in the myelin sheath, including ganglioside, sulfatide, cerebroside, sphingomyelin and tot...

Multiple sclerosis and its preclinical model, experimental autoimmune encephalomyelitis, are marked by perivascular inflammation and demyelination. Myeloid cells, derived from circulating progenitors, are a prominent component of the inflammatory infiltrate and are believed to directly contribute to demyelination and axonal damage. How the cytotoxic activity of these myeloid cells is regulated ...
