Bullous pemphigoid (BP) is an autoimmune and inflammatory skin disease associated with subepidermal blistering and autoantibodies directed against the hemidesmosomal components BP180 and BP230. Animal models of BP were developed by passively transferring anti-BP180 IgG into mice, which recapitulates the key features of human BP. By using these in vivo model systems, key cellular and molecular events leading to the BP disease phenotype are identified, including binding of pathogenic IgG to its target, complement activation of the classical pathway, mast cell degranulation, and infiltration and activation of neutrophils...

Among T helper (Th) cell subsets differentiated from naive CD4+ T cells, IL-17-producing Th17 cells are closely associated with the pathogenesis of autoimmune diseases, including multiple sclerosis (MS) and the MS animal model, experimental autoimmune encephalomyelitis (EAE). The modulation of Th17 differentiation offers a potential avenue for treatment. Although a series of microRNAs (miRNAs) that modulate autoimmune disease development have been reported, further studies on miRNA roles in Th17 differentiation and MS pathogenesis are still warranted...

BACKGROUND: Although several disease-modifying treatments are available for relapsing multiple sclerosis, treatment effects have been more modest in progressive multiple sclerosis and have been observed particularly in actively relapsing subgroups or those with lesion activity on imaging. We sought to assess whether natalizumab slows disease progression in secondary progressive multiple sclerosis, independent of relapses. METHODS: ASCEND was a phase 3, randomised, double-blind, placebo-controlled trial (part 1) with an optional 2 year open-label extension (part 2)...

BACKGROUND: Monitoring neuronal injury remains one key challenge in early relapsing-remitting multiple sclerosis (RRMS) patients. Upon axonal damage, neurofilament - a major component of the neuro-axonal cytoskeleton - is released into the cerebrospinal fluid (CSF) and subsequently peripheral blood. OBJECTIVE: To investigate the relevance of serum neurofilament light chain (sNfL) for acute and chronic axonal damage in early RRMS. METHODS: sNfL levels were determined in 74 patients (63 therapy-naive) with recently diagnosed clinically isolated syndrome (CIS) or RRMS using Single Molecule Array technology...

BACKGROUND: Restriction spectrum imaging (RSI) is a recently introduced magnetic resonance imaging diffusion technique. The utility of RSI in multiple sclerosis (MS) is unknown. OBJECTIVE: To investigate the association between RSI-derived parameters and neurological disability in MS. METHODS: Seventy-seven relapsing-remitting MS patients were scanned with RSI on a 3-T scanner. RSI-derived parameters: fast and slow apparent diffusion coefficient (sADC), fractional anisotropy, restricted fractional anisotropy, neurite density (ND), cellularity, extracellular water fraction, and free water fraction, were obtained in white matter lesions (WML) and normal appearing white matter (NAWM)...

OBJECTIVES: Multiple sclerosis (MS) is a chronic demyelinating disorder affecting young adults. Environmental factors and lifestyle behaviors are pivotal in MS pathophysiology. Smoking has been considered as an important risk factor in MS. Various recent studies have been conducted to measure the role of smoking on worsening disability in patients with MS, thus we intended to systematically assess effect of smoking on evolution of disability in this study. MATERIALS & METHODS: We queried MEDLINE, EMBASE and Cochrane Library with following keywords "Multiple Sclerosis, Smoking, Tobacco Use, Disability" on December 1st 2016...

Recently, we reported a positive correlation between Klotho, as an anti-aging protein, and the total antioxidant capacity (TAC) in cerebrospinal fluid (CSF) of multiple sclerosis (MS) patients. However, there is no information about the Klotho and TAC changes within the central nervous system (CNS). Thus, the current study aimed to employ an experimental autoimmune encephalomyelitis (EAE) model in C57BL/6 mice using MOG35-55 peptide to examine the relationship between Klotho and TAC within the CNS. To this end, the brain and spinal cord were obtained at the onset and peak stages of EAE as well as non-EAE mice (sham/control groups)...

INTRODUCTION: Antigen-specific immunotherapy could provide a targeted approach for the treatment of multiple sclerosis that removes the need for broad-acting immunomodulatory drugs. ATX-MS-1467 is a mixture of four peptides identified as the main immune-dominant disease-associated T-cell epitopes in myelin basic protein (MBP), an autoimmune target for activated autoreactive T cells in multiple sclerosis. Previous animal studies have shown that ATX-MS-1467 treatment prevented the worsening of signs of disease in experimental autoimmune encephalitis (EAE) in the humanized (DR2 × Ob1)F1 mouse in a dose-dependent fashion...

Background: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system which has no any known definitive treatment. Studies have shown that thyroid hormones (THs) in addition to their roles in the development of the nervous system and the production of myelin have important roles in the adult's brain function. Since the only way to treat MS is the restoration of myelin, the aim of this study was to evaluate the effects of levothyroxine on visual evoked potential (VEP) impairment following local injections of lysolecithin into the rat optic chiasm...

Tuberous sclerosis complex (TSC) is a genetic disorder characterized by tumor formation in multiple organs, with over 80% of TSC patients developing angiomyolipomas (TSC-AMLs). However, the molecular events that contribute to TSC-AMLs are not well understood. Recent reports have demonstrated that microRNAs (miRNAs) are critical in TSC cortical tubers. However, little is known about the role of miRNAs in TSC-AMLs. In the current study, we analyzed changes in the miRNA and mRNA profiles in TSC-AMLs and matched normal adjacent tissues...

Oligodendrocytes are the myelin-producing cells of the central nervous system (CNS). A variety of brain disorders from "classical" demyelinating diseases, such as multiple sclerosis, stroke, schizophrenia, depression, Down syndrome and autism, are shown myelination defects. Oligodendrocyte myelination is regulated by a complex interplay of intrinsic, epigenetic and extrinsic factors. Gpr17 (G protein-coupled receptor 17) is a G protein-coupled receptor, and has been identified to be a regulator for oligodendrocyte development...
