A strong transcription enhancer was identified in the genomic DNA (235 kb) of human cytomegalovirus (HCMV), a ubiquitous and severe pathogen of the herpesvirus group. Cotransfection of enhancerless SV40 DNA with randomly fragmented HCMV DNA yielded two SV40-HCMV recombinant viruses that had incorporated overlapping segments of HCMV DNA to substitute for the(More)
Matrix metalloproteinase-9 (MMP-9) was investigated by enzyme-linked immunosorbent assay (ELISA) and zymography in 111 paired CSF and serum samples from patients with various neurological disorders. In 20 patients with blood-brain barrier (BBB) impairment but normal CSF cell count, elevated levels of MMP-9 were not observed by ELISA measurement. Another 11(More)
OBJECTIVE To study the longitudinal dynamics of anti-myelin oligodendrocyte glycoprotein (MOG) autoantibodies in childhood demyelinating diseases. METHODS We addressed the kinetics of anti-MOG immunoglobulins in a prospective study comprising 77 pediatric patients. This was supplemented by a cross-sectional study analyzing 126 pediatric patients with(More)
The early transmembrane glycoprotein E19 of adenovirus-2 binds to class I antigens of the major histocompatibility complex (MHC). The association is initiated in the endoplasmic reticulum of infected cells and abrogates the intracellular transport of the class I molecules. To examine which parts of the E19 molecule are responsible for the association with(More)
BACKGROUND Lymphocytic infiltration of the skin (LIS) is a disorder in which photosensitivity has been suspected but never proven. OBJECTIVES To carry out a systematic photobiological investigation in patients with LIS and to compare the photobiological features of LIS with those of other photosensitive disorders. METHODS We performed provocative(More)
Using the simian virus 40 "enhancer trap" approach, we have identified a transcription enhancer located just upstream of the major immediate early gene of murine cytomegalovirus. This enhancer has several striking properties. (i) Together with the enhancer of human cytomegalovirus, it is the strongest transcription enhancer found to date. (ii) It is an(More)
OBJECTIVE To compare CSF filtration (CSFF) and plasma exchange (PE) in the treatment of patients with Guillain-Barré syndrome (GBS). METHODS In a prospective controlled clinical trial, 37 patients with acute GBS were randomized to receive either CSFF or PE. Inclusion criteria were fulfillment of National Institute of Neurological and Communicative(More)
Lymphotoxin (LT) and tumor necrosis factor-alpha (TNF-alpha) play an important role in the pathogenesis of multiple sclerosis (MS). MS is associated with the HLA-DR2, Dw2, DQ6 HLA class II haplotype. Because both LT and TNF-alpha are encoded in the HLA region, the HLA association of MS may be related to the production of these cytokines. To test this(More)
Subcutaneous application of interferon-beta1b (IFN-beta1b) is an established therapy for patients with relapsing-remitting multiple sclerosis (RRMS), but early side effects are still a major concern. In vitro studies with myelin basic protein (MBP)-specific T-cell lines revealed a synergistic suppressive effect of IFN-beta1b and the phosphodiesterase(More)
The soluble form of the CD14 molecule (sCD14), a macrophage activity marker, was measured in the plasma of 17 patients with primary progressive multiple sclerosis (PPMS) and 20 patients with relapsing remitting MS (RRMS). In patients with PPMS, sCD14 levels were determined before and after treatment with interferon beta (IFNB). In both PPMS and in RRMS,(More)
