G cytokines was replenished on day 3. Mo-DCs were further treated with either DMSO or 0.001M to- 10 M BaP in DMSO, or with polyinosinic:polycytidylic acid (Poly I:C) (12.5g/ ml) for 24 hr. Purity and maturation of DCs was assessed by staining with monoclonal antibodies to CD14, CD11c and CD83 (BD Biosciences, San Jose, California, USA) and FACS analysis. Immature mo-DCs were CD14-, CD11c+, CD83low and as expected became CD14-, CD11c+, CD83high upon PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/11011031 maturation induced by Poly I:C stimulation.Quantitation by real-time polymerase chain reaction (RT-PCR)sequence detection system. The SYBR Green primers (Invitrogen) were AHR (sense): 5'-TTC AGT TCT TAG GCT CAG CGT -3', AHR (antisense): 5'-TGC TGC TCT ACA GTT ATC CTG G -3' and GAPDH (sense): 5'- TGC ACC ACC AAC TGC TTA GC -3', GAPDH (antisense): 5'GGC ATG GAC TGT GGT CAT GAG -3'. Commercially available Taqman assays (Applied Biosystems, Foster City, California, USA) were used to measure CYP1A1 (Hs00153120_m1), AHRR (Hs01005075_m1), IL17A (Hs00174383_m1), 1-Hexanol IL17F (Hs00369400_m1), IFNG (Hs00174143_m1), IL22 (Hs01574154_m1), IL23A (Hs00372324_m1), IL23R (Hs00332759_m1), FOXP3 (Hs00203958_m1), IL6 (Hs00985639_m1), IDO1 (Hs00984148_m1), TBX21 (Hs00203436_m1) and GAPDH (Hs99999905_m1) gene expression. All samples were assessed in triplicate. Samples were considered negative for gene expression when threshold cycle (Ct) values were <40. Positive, test sample Ct values were extrapolated to standard curves obtained from human tonsil or lung standards, to calculate the mean amount of gene-specific RNA in each sample. Results are expressed as the mean ?SEM ng RNA for each gene of interest, relative to the expression of glyceraldehede-3-phosphate dehydrogenase (GAPDH) RNA.Double immunofluorescenceTotal RNA was purified from rheumatoid nodule and synovial tissues or from cultured cells, and reverse transcribed using Superscript III (Invitrogen, Carlsbad, California, USA) as previously described [31]. Gene expression was assessed by RT-PCR using SYBR Green or TaqMan gene expression assays on an Applied Biosystems ABISeven-m sections of frozen synovial tissues were cut and fixed in acetone for 10 minutess at 4 . After blocking with 5 goat immunoglobulins (IgGs; Sigma, Saint Louis, Missouri, USA) for 30 minutes at room temperature, the sections were incubated separately with cell-specific mouse monoclonal anti-CD3 (T cells; clone UCHT1), anti-CD20 (B cells; clone L26; DAKO, Glostrup, Denmark), anti-CD14 (monocytes/macrophages; clone FMC17), anti-DCs (clones CMRF44 [32] and CMRF56 [33,34]), anti-CD303(BDCA-2) (pDCs; clone AC144; Miltenyi Biotec), anti-CD1 (imDC; clone Na134), or anti-prolyl 4hydroxylase (fibroblast; clone 5B5; Abcam, Cambridge, UK) overnight at 4 , followed by incubation withKazantseva et al. Arthritis Research Therapy 2012, 14:R208 http://arthritis-research.com/content/14/5/RPage 4 ofAlexaFluor568-conjugated goat anti-mouse antibody (diluted 1:1500; Invitrogen) for 1.5 hr at 4 . The sections were then blocked with 5 mouse IgGs for 30 minutes at room temperature following by incubation with biotinylated mAbs either against AHR (clone RPT9; Abcam) or CYP1A1 (clone b-2; Santa Cruz Biotechnology, Santa Cruz, California, USA) overnight, at 4 with subsequent incubation with AlexaFluor488-conjugated streptavidin (10g/ml; Invitrogen) for 30 minutes, at RT. Cell nuclei were identified by counterstaining with Hoechst 33342 (2.5 g/ml). Negative controls included the omission of primary antibodies an.
