Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). So far, immunological mechanisms responsible for demyelination have been the focus of interest. However, mechanisms regulating axon maintenance as well as glial precursor-cell proliferation and oligodendrocyte survival might also influence disease outcome. The(More)
Monocyte/macrophage differentiation was studied in biopsy samples of multiple sclerosis (MS) lesions obtained in the early course of the disease. Macrophages were identified by immunocytochemistry using a panel of antibodies recognizing different macrophage-activation antigens. The number of cells stained with each antibody was related to the demyelinating(More)
Inflammation has always been thought of as detrimental in the pathophysiology of multiple sclerosis (MS). However, emerging genetic data, magnetic-resonance-imaging studies, and immunopathological evidence challenge this simplistic view. The evidence leads to the conclusion that inflammation is tightly regulated, and that its net effect may be beneficial in(More)
Alzheimer's disease (AD) probably involves several pathobiochemical mechanisms and this may be reflected by changes in different serum components. The present study investigated whether the combined analysis of serum molecules related to different mechanisms improves the discrimination of AD patients from healthy controls. Serum of patients with AD was(More)
BACKGROUND Immune-mediated demyelination and axonal damage lead to early functional impairment in multiple sclerosis (MS). Ciliary neurotrophic factor (CNTF) is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. SUBJECTS AND METHODS We screened 288 unselected patients(More)
BACKGROUND Mitochondrial DNA (mtDNA) polymorphism is a possible factor contributing to the maternal parent-of-origin effect in multiple sclerosis (MS) susceptibility. METHODS AND FINDINGS In order to investigate the role of mtDNA variations in MS, we investigated six European MS case-control cohorts comprising >5,000 individuals. Three well matched(More)
BACKGROUND Primary progressive multiple sclerosis (PPMS) carries the worst prognosis of the multiple sclerosis (MS) subtypes and is currently untreatable. A previous analysis of the British Columbia MS database challenged the view that disability progression is rapid in PPMS, but identified few predictors of disease progression. Here, we extend previous(More)
BACKGROUND On the basis of various clinical and MRI measurements, the phase 3 Cladribine Tablets Treating Multiple Sclerosis Orally (CLARITY) study in patients with relapsing-remitting multiple sclerosis (RRMS) showed that short-course oral treatment with cladribine at cumulative doses of 3·5 and 5·25 mg/kg over 96 weeks was more effective than placebo.(More)
CONTEXT Brain atrophy is an indicator of diffuse brain pathology that appears even in the early stages of multiple sclerosis (MS). Magnetic resonance imaging (MRI) techniques used in clinical trials suggest a correlation between ventricular enlargement and axonal pathology and clinical disability in MS. OBJECTIVE To evaluate by transcranial sonography(More)
