Published 2000Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Pemphigus vulgaris (PV) is an autoimmune blistering disease characterized by circulating pathogenic IgG antibodies against desmoglein 3 (Dsg3). The purpose of this study was to develop chimeric molecules for specific recognition and elimination of autoimmune B cells in PV. Mouse hybridoma cell lines producing anti-Dsg3 antibody (5H10, 12A2) were developed as an in vitro model system for targeting B cells. Dsg3-GFP, a baculoprotein containing the entire extracellular domain of Dsg3 fused with green fluorescence protein, recognized and targeted the hybridoma cells through their surface immunoglobulin receptors in an antigen-specific way. The epitopes of these monoclonal antibodies were mapped on the amino terminal EC1 and part of EC2, a region considered functionally important in cadherins. Chimeric toxin molecules containing the mapped region (Dsg3ΔN1) and modified Pseudomonas exotoxin were produced in bacteria (Dsg3ΔN1-PE40-KDEL, PE37-Dsg3ΔN1-KDEL) and tested in vitro on hybridoma cell lines. The chimeric toxins, but not Dsg3ΔN1 alone, showed dose-dependent toxic activity with a reduction in hybridoma cell number to 40–60% of toxin-negative control cultures, compared with little or no effect on anti-Dsg3-negative hybridoma cells. Furthermore, these toxins showed toxic effects on anti-Dsg3 IgG-producing B cells from Dsg3ΔN1-immunized mice, with a 60% reduction in cell number compared with Dsg3ΔN1 alone. Thus, specific recognition and targeting of antigen-specific B cells in PV was demonstrated; this strategy may hold promise as a future therapeutic option for PV and other autoimmune diseases.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1365-2230Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Eosinophilic pustular folliculitis (EPF) is characterized by erythematous patches of large follicular papules and pustules involving mainly the face. Although various treatments have been attempted for EPF, including systemic and topical steroid, diaphenylsulphone, colchicine, minocycline as well as UVB phototherapy, there is no consensus on the first choice of treatment. We report a typical case and summarize 25 patients with EPF treated in our hospital between 1978 and 1998. Indomethacin was most frequently used (12/25) and showed clinical improvement in the majority of the cases (11/12). The effect of indomethacin was usually observed within 1–2 weeks after initiation of treatment. Decrease of peripheral blood eosinophils accompanied the clinical improvement. Thus, indomethacin should be considered as a first choice of treatment for EPF.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1440-1738Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesNotes: Abstract Ultrahigh-pressure metamorphic (UHPM) rocks of the Kokchetav Massif of Kazakhstan contain metamorphic microdiamond and coesite inclusions inside rigid capsules such as garnet and zircon. Precambrian protoliths of the UHPM rocks were metamorphosed at around 530 Ma, at pressures of about 7 GPa, which suggests that crustal protoliths were subducted to depths of over 200 km. Primary UHPM minerals are poorly preserved due to partial obliteration by subsequent Barrovian overprint during exhumation and later collision events in Caledonian times. We report the results of detailed mapping of the Kokchetav Massif and use structural data to propose intrusion and exhumation mechanisms for the UHPM rocks. Detailed mapping revealed that many subvertical structures in the ultrahigh-pressure–high-pressure (UHP–HP) units were formed due to later folding. The primary structure appears to be subhorizontal and the total thickness of the UHP rocks is estimated at around 2 km. The first order structure is sandwich-like; that is, the UHP–HP units are separated from underlying low-P metamorphic rocks of the Daulet Series and from feebly metamorphosed to unmetamorphosed sedimentary strata on the top by subhorizontal faults. Kinematic indicators show top-to-the-south sense of shear along the top, and top-to-the-north displacement along the bottom boundaries. These shear senses, together with the observed metamorphic gradients, suggest that the thin UHPM sheet was extruded toward the north. We consider wedge extrusion to have been the most effective mechanism for the exhumation of the UHPM rocks.Type of Medium: Electronic ResourceURL: -

Published 2004Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Pemphigus vulgaris (PV) is an autoimmune blistering disease caused by antidesmoglein3 (anti-Dsg3) IgG autoantibodies. Recently, we developed a PV mouse model by adoptive transfer of splenocytes from recombinant Dsg3-immunized Dsg3–/– mice to Rag2–/– immunodeficient mice that expressed Dsg3.Objectives We determined whether the adoptive transfer of naive splenocytes from nonimmunized Dsg3–/– mice induces the anti-Dsg3 IgG production and the PV phenoytpe in recipient mice.Methods We adoptively transferred naive Dsg3–/– splenocytes into Rag2–/– mice and compared their PV phenoytpe with those mice receiving immunized Dsg3–/– splenocytes. The numbers of splenocytes and their subpopulations required for anti-Dsg3 IgG production were examined.Results Mice that received naive Dsg3–/– splenocytes produced anti-Dsg3 IgG, which bound to keratinocyte cell surfaces in vivo, and developed the PV phenotype, including oral erosions with suprabasilar acantholysis. Antibody production and the appearance of the PV phenotype were delayed by approximately 2 weeks in mice that received naive splenocytes compared with mice that received immunized splenocytes. However, once the PV phenotypes developed, there were no apparent differences in disease severity between the two models. Interestingly, the anti-Dsg3 IgG titres were significantly lower in mice that received naive splenocytes than in mice that received immunized splenocytes, suggesting that the former antibodies were more potent than the latter. The frequency of anti-Dsg3 IgG production depended on the number of transferred naive splenocytes. Both CD4+ T cells and B220+ B cells from naive Dsg3–/– mice were essential for the production of anti-Dsg3 IgG antibodies.Conclusions Dsg3-specific naive lymphocytes in Dsg3–/– mice can be primed and activated by the endogenous Dsg3 in recipient mice to produce pathogenic anti-Dsg3 IgG without active immunization. This approach using naive lymphocytes provides a unique model to dissect immunological mechanisms of tolerance against peripheral autoimmune targets.Type of Medium: Electronic ResourceURL: -
