Pep and CD45 are tyrosine phosphatases whose targets include the Src-family kinases, critical mediators of Ag receptor signaling. A polymorphism in PTPN22, the gene that encodes the human Pep orthologue Lyp, confers susceptibility to multiple human autoimmune diseases in the context of complex genetic backgrounds. However, the functional significance of the(More)
OBJECTIVE To investigate the rate of seropositivity of anti-JC virus (JCV) antibodies in a German multiple sclerosis (MS) cohort treated with natalizumab in the postmarketing setting and to assess anti-JCV serostatus in samples obtained before diagnosis of progressive multifocal leukoencephalopathy (PML). METHODS This was a blinded, retrospective(More)
STUDY OBJECTIVES To compare the craniofacial morphological phenotype of subjects with and without obstructive sleep apnea (OSA) using a quantitative photographic analysis technique. DESIGN Case-control study; subgroup matched for body mass index (BMI) and sex. SETTING Sleep investigation unit in a university teaching hospital. PATIENTS 114 subjects(More)
STUDY OBJECTIVES We hypothesized that the facial phenotype is closely linked to upper airway anatomy. The aim of this study was to investigate the relationship between surface facial dimensions and upper airway structures using magnetic resonance imaging (MRI) in subjects with obstructive sleep apnea (OSA). DESIGN Cohort study. SETTING Sleep(More)
STUDY OBJECTIVES To develop models based on craniofacial photographic analysis for the prediction of obstructive sleep apnea (OSA). DESIGN Prospective cohort study. SETTING Sleep investigation unit in a university teaching hospital. PATIENTS One hundred eighty subjects (95.6% Caucasian) referred for the initial investigation of OSA were recruited(More)
OBJECTIVE To find biomarkers identifying patients at risk for the development of progressive multifocal leukoencephalopathy (PML) during natalizumab treatment. METHODS Patients were recruited from 10 European and US cohorts. Of 289 patients with multiple sclerosis (MS), 224 had been treated with natalizumab (18-80 months), 21 received other(More)
The diagnosis of primary central nervous system lymphoma (PCNSL) depends on histopathology of brain biopsies, because disease markers in the cerebrospinal fluid (CSF) with sufficient diagnostic accuracy are not available yet. MicroRNAs (miRNAs) are regulatory RNA molecules that are deregulated in many disease types, including cancer. Recently, miRNAs have(More)
Idiopathic pulmonary fibrosis (IPF) is a progressively fibrotic interstitial lung disease that is associated with a median survival of 2-3 years from initial diagnosis. To date, there is no treatment approved for IPF in the United States, and only one pharmacological agent has been approved outside of the United States. Nevertheless, research over the past(More)
BACKGROUND Huntington disease (HD) is an inherited neurodegenerative disease caused by an abnormal expansion of a CAG repeat in the huntingtin HTT (HD) gene. The primary genetic determinant of the age at onset (AO) is the length of the HTT CAG repeat; however, the remaining genetic contribution to the AO of HD has largely not been elucidated. Recent studies(More)
The present study investigates the immunological effects of a combination treatment of mitoxantrone and the cardioprotector dexrazoxane in experimental autoimmune encephalomyelitis (EAE). Mitoxantrone, an anthracycline-derived immunosuppressive drug has been approved recently for treatment of very active multiple sclerosis (MS). Its prolonged use is limited(More)
