The expression of caveolin-1, -2, and -3 in the spinal cords of Lewis rats with experimental autoimmune encephalomyelitis (EAE) was analyzed. Western blot analysis showed that three isotypes of caveolins including caveolin-1, -2 and -3 increased significantly in the spinal cords of rats during the early stage of EAE, as compared with the levels in control(More)
The pathological hallmarks of secondary progressive (SP) multiple sclerosis (MS) include slowly expanding demyelination and axonal damage with less inflammation. To elucidate the pathomechanisms of secondary progressive (SP) multiple sclerosis (MS), we have investigated the expression of chemokines, chemokine receptors, matrix metalloproteinase-9 (MMP-9)(More)
Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system that can be induced by immunization with myelin basic protein (MBP)/complete Freund's adjuvant and serves as a model for multiple sclerosis. Recent studies have suggested that cytokines play a crucial role in the clinical course of EAE. To clarify the(More)
Preliminary observations of humoral immunity against the myelin oligodendrocyte glycoprotein (MOG) in experimental allergic encephalomyelitis (EAE) and human multiple sclerosis (MS) suggest that a subset of anti-MOG autoantibodies directed against conformational epitopes is of pathogenic predominance. Here, we provide proof that in marmoset EAE,(More)
To elucidate the role of NK cells and TCR gamma delta+ T cells in acute experimental autoimmune encephalomyelitis (EAE) induced in Lewis rats, the distribution, number and function of these cells were studied using several methods. Immunohistochemical and flow cytometric analysis revealed that a certain number of NK cells (17 of the total inflammatory(More)
To characterize the phenotype of inflammatory cells in the central nervous system (CNS) in experimental autoimmune encephalomyelitis (EAE), Lewis rats were immunized with guinea pig myelin basic protein and frozen sections of the spinal cord with EAE were examined immunohistochemically using a panel of monoclonal antibodies against T cells and adhesion(More)
Myelin/oligodendrocyte glycoprotein (MOG) is a surface-exposed antigen of myelin and an important target for autoimmune responses which mediate inflammatory demyelination in the central nervous system. Experimentally, MOG induces strong pathogenic T cell responses in many strains of laboratory animals. Immunological studies in humans also identify MOG as a(More)
To elucidate the factor(s) accelerating the autoimmune disease processes, we induced two types of experimental autoimmune encephalomyelitis (EAE), severe and very mild, in F344 rats by immunization with myelin basic protein (MBP) plus pertussis toxin (PT) (PT+) or with MBP alone (PT-) and compared the differences between the two. Immunohistochemical(More)
Dentatorubral-pallidoluysian atrophy (DRPLA) is one of the CAG-repeat diseases, and is classified into juvenile and early adult types showing progressive myoclonus epilepsy (PME) in addition to late adult type. We immunohistochemically examined accumulation of oxidative products and expression of superoxide dismutase (SOD) in autopsy cases of DRPLA.(More)
Experimental autoimmune encephalomyelitis (EAE) is a disease model of multiple sclerosis (MS) that is characterized by remittance and relapse of the disease and autoimmune and demyelinating lesions in the central nervous system (CNS). To better understand the mechanism of disease relapse, we induced acute and chronic relapsing (CR)-EAE in Lewis rats and(More)
