Growing evidence suggests that interleukin (IL)-17 and IL-17-secreting CD4(+)T (Th17) cells are involved in the pathogenic mechanisms of multiple sclerosis (MS). IL-17-secreting CD8(+)T cells were recently identified as a novel subset of CD8(+)T cells. We aimed to analyze the role of Th17 and IL-17 secreting CD8(+)T cells in the pathogenesis of(More)
Soluble egg antigen (SEA) is strongly antigenic and inherently induces Th2-biased immune responses. In this study, we tested whether SEA from Schistosoma japonicum is able to prevent experimental autoimmune encephalomyelitis (EAE) induced by MOG(35-55) peptide, an established animal model of multiple sclerosis (MS). Intraperitoneal administration with SEA(More)
Lysosomes are acidic organelles that have a crucial role in degrading intracellular macromolecules and organelles during the final stage of autophagy. Tetrandrine (Tet), a bisbenzylisoquinoline alkaloid, was reported as an autophagy activator. Here, in contrast with previous studies, we show that Tet is a potent lysosomal deacidification agent and is able(More)
Ulinastatin has previously been used as a drug for patients with acute inflammatory disorders. The goal of the present study was to investigate the protective effects of ulinastatin on myelin sheaths and oligodendrocytes in experimental autoimmune encephalomyelitis (EAE), and to explore the possible underlying mechanism. Mice were divided into an(More)
OBJECTIVES To determine the frequency of hypothalamic lesions in patients with multiple sclerosis (MS) using conventional MRI (cMRI) protocols. METHODS Brain cMRI (1.5 Tesla) scans of 105 Caucasian patients with classical MS (50 with stable and 55 with more active disease) and 12 patients with longitudinal extensive myelopathy (LEM) were reviewed(More)
OBJECTIVES To analyze the role of HLA-DRB1 and -DPB1 alleles in the pathogenesis of neuromyelitis optica (NMO) and multiple sclerosis in Southern Han Chinese. METHODS Thirty serum anti-aquaporin 4 antibodies (AQP4-Ab)-positive NMO patients, 53 conventional multiple sclerosis (C-MS) patients, and 93 controls (CTLs) were enrolled. The HLA-DRB1 and -DPB1(More)
BACKGROUND IL-6 is a proinflammatory cytokine which is involved in the maintenance of the humoral response in various autoimmune disorders. Cerebrospinal fluid (CSF) IL-6 has shown to be increased in neuromyelitis optica (NMO). The soluble form of IL-6 receptor (sIL-6R), which links to IL-6, can activate biological responses in cells. Whether or not sIL-6R(More)
The apoptosis of glomerular mesangial cells (GMCs) in rat Thy-1 nephritis (Thy-1N), a model of human mesangioproliferative glomerulonephritis (MsPGN), is accompanied by sublytic C5b-9 deposition. However, the mechanism by which sublytic C5b-9 induces GMC apoptosis is unclear. In the present studies, the effect of X-linked inhibitor of apoptosis-associated(More)
OBJECTIVE To determine the Helicobacter pylori infection status in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO) spectrum. METHODS H. pylori infection was certified by indirect immunofluorescence assay. Aquaporin-4 (AQP4) antibody was detected by cell-based assay. H. pylori seroprevalence was measured in 118 patients with NMO (n =(More)
Uric acid (UA) has been reported to be reduced in the serum of patients with multiple sclerosis (MS) and optic neuritis (ON). However, the relationship between UA and neuromyelitis optica (NMO) was unknown. NMO was claimed to be a distinct nosologic entity from MS. The aim of our study was to investigate the correlation between serum UA level and the(More)
