Figure Lengend Snippet: Figure 1 RT-PCR analysis of CXCL10, CXCL9, and CXCL11 gene expression in freshly isolated Langerhans cells (fLC), 48 h cultured LC (cLC), interferon-c (IFN-c)-stimulated cLC (c-cLC), freshly isolated splenic dendritic cells (fDC), 48 h cultured splenic DC (cDC), and IFN-c- stimulated cDC (c-cDC). LC and splenic DC were purified and cul- tured for 48 h in the absence or presence of 100 ng per mL of IFN-g. Samples from fresh and cultured LC and splenic DC were collected and mRNA expression was analyzed using specific primers for each chemokine. CXCL10, CXCL9, and CXCL11 mRNA expression was hardly detectable in fLC. In cLC, mRNA expression of CXCL10 and CXCL11, but not CXCL9, was induced. CXCL9 mRNA was strongly expressed only in g-cLC. In addition, mRNA for CXCL10 and CXCL11 was also strongly expressed in g-cLC. In splenic DC, mRNA for these T helper 1(Th1)-type chemokines was almost undetectable both in fDC and cDC. When stimulated with IFN-g, CXCL10, CXCL9, and CXCL11 mRNA expression was induced. Data are representative of three inde- pendent experiments.

Figure Lengend Snippet: Figure 2 Production of T helper 1-type chemokines during culture of Langerhans cells (LC) and splenic dendritic cells (DC). Purified LC and splenic DC were cultured with or without interferon-g (IFN-g), and the concentration of CXCL10, CXCL9, and CXCL11 was measured at different time points (0, 12, 24, 36, 48 h) in the supernatants by ELISA. Representative data of three independent experiments.

Figure Lengend Snippet: Figure 3 Chemotaxis of mCXCR3-transfected 2B4 T cells. Langerhans cells (LC) and splenic dendritic cells (DC) were cultured for 48 h with 100 ng per mL of interferon-g (IFN-g) and the supernatants were collected. The culture supernatants were preincubated with or without neutralizing anti-chemokine monoclonal antibody (mAb) indicated in the figure for 30 min, and assessed for chemotactic activity to CXCR3 transfectant. RPMI 10 medium alone served as a negative control. RPMI 10 medium containing recombinant chemokine served as a positive control. The supernatants of IFN-g-stimulated LC and splenic DC exhibited chemo- tactic activity to CXCR3 transfectant, which is mediated at least by CXCL10 and CXCL9. Mean (SD) (n ¼ 3). Data are representative of three independent experiments.

Figure Lengend Snippet: Figure 7 Regulation of T helper 1-type chemokines produced by La- ngerhans cells (LC) and splenic dendritic cells (DC). LC (&) and splenic DC (’) were purified and cultured (1.5 106 cells per mL per 200 mL in each well) for 48 h with or without various stimuli. The supe- rnatants were collected and the concentration of CXCL10 (a), CXCL9 (b), and CXCL11 (c) was measured by ELISA. CXCL10 production by LC was induced by interferon-g (IFN-g), interleukin (IL)-12, lipopoly- saccharide (LPS), Staphylococcus aureus Cowen 1 (SAC), and poly- inosinic–polycytidylic acid (Poly(I:C)). In the case of CXCL9 and CXCL11, only IFN-g induced their production by LC. In the case of splenic DC, the production of CXCL10, CXCL9, and CXCL11 was in- duced by IFN-g, IL-18, LPS, and Poly(I:C). Results are the mean (SD) (n ¼ 4). Significant increase (po0.05) compared with the unstimulated group. Data are representative of four independent experiments.
