Figure Lengend Snippet: ( A to G ) CD8 + T cells isolated from healthy donor were cultured in the plate coated with anti–human CD3/CD28 (10 μg/ml) for indicated days in the presence of vehicle control (control), IFN-α (100 ng/ml), IL-6 (100 ng/ml), IL-12 (100 ng/ml), or the combination. (A) Summaries of the percentage of CD38 + CD127 − CD8 + T cells at days 1 and 5. (B) MFI of CD69 (day 5). (C) MFI of CD25 (day 5). (D) Activated CD8 + T cells were restimulated with PMA, ionomycin, and monensin for 5 hours; expression of granzyme B and IFN-γ in CD8 + T cells was examined. [(E) to (G)] CD8 + T cells were cultured for 5 days. MFIs (all relative to those under control condition) of MTDR (E), MTG (F), and GluCy5 (G) were summarized. ( H to L ) CD4 + T cells were isolated from HC, cultured in the plate coated with anti–human CD3/CD28 (10 μg/ml) for indicated days in the presence of IFN-α (100 ng/ml), IL-6 (100 ng/ml), IL-12 (100 ng/ml), control, or the combination of them. (H) Activated CD4 + T cells were restimulated with PMA, ionomycin, and monensin for 5 hours, and IL-21 level was examined in the CD45RA − CD4 + T cells. (I) Activated CD4 + T cells were restimulated with plate-coated anti–human CD3/CD28 (10 μg/ml) with monensin for 6 hours, and expression of CXCL13 was measured in CD45RA − CD4 + T cells. (J) CD38 and CXCR5 were examined on CD4 + T cells at day 5. (K) Percentage of CXCL13 + cells in indicated T cells at day 5. (L) Percentage of IL-21 + cells in indicated T cells at day 5. Data in graphs represent mean ± SEM. Significance was tested by one-way ANOVA.
Article Snippet: For CXCL13, IL-21, and CX3CL1 measurements, the following kits were used: Human CXCL13/BLC/BCA-1 Quantikine Enzyme-Linked Immunosorbent Assay (ELISA) (R&D Systems, catalog no. DCX130), Human IL-21 DuoSet ELISA (R&D Systems, catalog no. DY8879-05), and Human CX3CL1/Fractalkine DuoSet ELISA (R&D Systems, DY365); all steps were performed according to the manufacturer’s instructions.
Techniques: Isolation, Cell Culture, Control, Expressing
