Human mesenchymal stem cells (MSC) derived from perirenal adipose tissue (PV) of living kidney donors were cultured under various conditions, namely (1) control (medium+foetal bovine serum(FBS)) or (2) control (medium+heat-inactivated FBS); (3) with mixed-lympohocyte reactions (MLR) in transwell culture systems for 4 days; (4) with mixed-lympohocyte reactions (MLR) in transwell culture systems for 7 days; or (5)with pro-inflammatory cytokines(IFNgamma, TNFalpha and interleukin 6).

View SamplesAnimal models have enhanced our understanding of the pathogenesis of autoimmune diseases. For these models, genetically identical, inbred mice have commonly been used. Different inbred mouse strains, however, show a high variability in disease manifestation. Identifying the factors that influence this disease variability could provide unrecognized insights into pathogenesis. We established a novel antibody transfer-induced model of epidermolysis bullosa acquisita (EBA), an autoimmune disease characterized by (muco)-cutaneous blistering caused by anti-type VII collagen (COL7) autoantibodies. Blistering after anti-COL7 IgG (directed against the von-Willebrand-factor A like domain 2) transfer showed clear variability among inbred mouse strains; i.e. severe cutaneous blistering and inflammation in C57Bl/6J, and absence of skin lesions in MRL/MpJ mice. The transfer of anti-COL7 IgG into irradiated, EBA-resistant MRL/MpJ mice, rescued by transplantation with bone marrow from EBA-susceptible B6.AK-H2k mice, induced blistering. To the contrary, irradiated EBA-susceptible B6.AK-H2k mice that were rescued using MRL/MpJ bone marrow were devoid of blistering. In vitro, immune complex activation of neutrophils from C57Bl/6J or MRL/MpJ mice showed an impaired ROS release from the latter, whereas no differences were observed after PMA activation. This finding was paralleled by divergent expression profiles of immune-complex activated neutrophils from either C57Bl/6J or MRL/MpJ mice. Collectively, we demonstrate that radiosensitive cells determine the varying extent of skin inflammation and blistering in the end-stage effector phase of EBA.

View Samples10 adult participants of dose group 3x10^6 pfu, and 10 participants of dose group 20x10^6 pfu. Reads were aligned to the human reference assembly (GRCh38.p7) using STAR software (v2.4.2a; option ''--quantMode GeneCounts''). Gene annotation was obtained from Ensembl (release 79, ensemble.org). VOOM+Limma analysis (R software, version 3.2.2) was used to assess differential gene expression at each post-vaccination day (d1, d3 and d7) against baseline (d0). Next, we intergreted gene expression data and antibody response using an sPLS algorithm, in order to down-select genes correlating with multivariate antibody responses at days 28, 54, 84,180. Overall design: 56 samples from D0, D1, D3 and D7 were analysed. Data from samples with low RIN (RIN <8, 17 samples), low RNA or library concentration (2 samples), missing samples (5 samples) were set to missing.

View SamplesThe goal of this study was to identify the molecular characteristics and putative markers distinguishing IL-10eGFP+CD138hi and IL-10eGFP-CD138hi plasmocytes. To this end, IL-10eGFP B-green mice were challenged intravenously with Salmonella typhimurium (strain SL7207, 10e7 CFU), and IL-10eGFP+CD138hi as well as IL-10eGFP-CD138hi plasmocytes were isolated from the spleen on the next day. For this, single cell suspensions were prepared, cells were treated with Fc block (10 g/ml, anti-CD16/CD32, clone 2.4G2), and then stained with an antibody against CD138 conjugated to PE (1/400; from BD Pharmingen) followed by incubation with anti-PE microbeads (Miltenyi Biotech). CD138+ cells were then enriched on Automacs (Miltenyi Biotech) using the program possel_d2. Cells were then stained with anti-CD19-PerCP, anti-CD138-PE, and antibodies against CD11b, CD11c, and TCR conjugated to APC as a dump channel to exclude possible contaminants. DAPI was added to exclude dead cells. Live IL-10eGFP+CD138hi and IL-10eGFP-CD138hi cells were subsequently isolated on a cell sorter. The purity of the samples was always above 98%. This led to the identification of LAG-3 as a cell surface receptor specifically expressed on IL-10eGFP+CD138hi cells but not on IL-10eGFP-CD138hi cells.
