For the detection of homologies between multiple short DNA and protein sequences, the ClustalW algorithm of the MacVector7.0 software or the BLAST 2 SEQUENCES LY2157299 concentration Version of the NCBI BLAST algorithm was used. Construction of phylogenetic trees. Phylogenetic trees were constructed with the EBI ClustalW tool (available at: http://www.ebi.ac.uk/clustalw/) using the CTLD sequences of the lectin-like genes starting from the first highly conserved cysteine
residue. Scanning of UTR sequences. The investigation into the human CLEC9A UTR was performed using UTRScan, UTRdb and UTRblast (all available at: http://utrsite.ba.itb.cnr.it/). Cells. Human umbilical vein endothelial cells (HUVEC) were isolated and cultured as described [13]. In short, cells were grown in M199 medium (Lonza, Basel, Switzerland) with 20% FCS, 2 ml/500 ml endothelial cell growth supplement (PromoCell, Heidelberg, Germany), 2 U/ml heparin (Roche, Mannheim, Germany) and 10 ml/500 ml PSFG (penicillin 10,000 U/ml, streptomycin 10 mg/ml, fungizon, see more 200 mmol glutamin (Lonza) in a 5% CO2 atmosphere at 37 °C. Venous peripheral blood of healthy volunteers was obtained from Red Cross (Vienna, Austria), and peripheral blood mononuclear cells (PBMC) were isolated by Ficoll-Paque™ PLUS (GE Healthcare, Freiburg, Germany) gradient centrifugation according to the manufacturer’s
instructions. Cord blood dendritic cells (CBDC) were kindly provided by Dr. Frank Kalthoff (Novartis, Vienna, Austria). Suspension cell lines used: 721.221, Mono-Mac-6, K-562, Jurkat, U-937, CCRF-CEM, P815, NK-92 and
RPMI-8866 were all grown in RPMI1640 medium (Life Technologies Ltd., Paisley, UK) containing 10% FCS and 10 mm l-glutamine (Lonza) in a 5% CO2 atmosphere at 37 °C. NK-92 cultures were supplemented in addition with 1 mm sodium pyruvate, 50 mmβ-mercaptoethanol (both Sigma-Aldrich, Gillingham, UK) and human rIL-2 (R&D Systems, Wiesbaden, Germany) at a final concentration of 20 IU/ml. Tacrolimus (FK506) Stimulation of cells. CBDC were stimulated for maturation with 100 ng/ml LPS (Sigma-Aldrich), 4 μg/ml of anti-CD40 mAb (mAb clone 626.2) cross-linked in solution by the addition of 2 μg/ml of F(ab’)2-fragments of goat anti-mouse IgG (Pierce Chemical Corp, Rockford, IL, USA), 25 μg/ml Zymosan A (Sigma-Aldrich) or 10 ng/ml IFN-γ for 6 h. Stimulation of the cells was verified by real-time RT-PCR showing the upregulation of E-Selectin mRNA in HUVEC and CCL22 (chemokine (C-C motif) ligand 22) mRNA in dendritic cells by real-time RT-PCR. RNA isolation and real-time RT-PCR. Total cellular RNA was isolated following cell lysis in Trizol (Invitrogen, Groningen, The Netherlands) by chloroform extraction and precipitation of the RNA using isopropanol. RNA were reverse transcribed into cDNA (SuperscriptTM II RT, Invitrogen) using oligo-dT primers, and real-time RT-PCR was used to monitor gene expression using a Light Cycler instrument (Roche Diagnostics GmbH, Mannheim, Germany) according to established procedures [20].
