Experiment Type: Cytokine detection by flow cytometry
On the day of testing the cells were washed twice (5 min at 925 × g) with PBS and 0.1% (wt/vol) saponin (Sigma) (PBS-S) supplemented with 1% plasma from the animal under investigation. These fixed and saponin-treated cells were then transferred to U-bottom microtiter plates (0.2 × 106 to 1 × 106 cells in a volume of 50 μl), and the plates were incubated for 1 h at room temperature with 500 ng of MAbs. B. Aasted et al. used the following four MAbs: a cross-reactive anti-ovine IL-8-specific MAb (Serotec MCA 1660; immunoglobulin G2a [IgG2a] isotype), a cross-reactive anti-bovine IL-4-specific MAb (Serotec MCA 1820; IgG2a isotype), a cross-reactive anti-bovine γ-IFN-specific MAb (Serotec MCA 1783; IgG1 isotype), and an anti-porcine TNF-α-specific MAb (Endogen MP-390; IgG1 isotype). Nonreactive MAbs of the IgG1 isotype (DAK-G01; Dako) and the IgG2a isotype (DAK-G05; Dako) were used to stain the isotype controls. The cells were then washed twice with PBS-S and incubated with 500 ng of a fluorescein isothiocyanate-conjugated F(ab′)2 fragment of a rabbit anti-mouse immunoglobulin (F313; Dako). The cells were then washed once in PBS-S and once in FACS sheath fluid (J. T. Baker, Deventer, The Netherlands) and analyzed with a Calibur flow cytometer (Becton Dickinson, San Jose, Calif.). The results presented in this study were based on lymphocyte gating on a forward scatter-versus-side scatter diagram. All cells outside the lymphocyte gate (region 1) are named and regarded as monocytes (named macrophages in the lymph node preparations). Fluorescent histogram markers were defined and quantitated positively from negatively stained cells. The percentage of cytokine-positive cells was calculated after subtraction of eventual positive signals from the isotype control immunoglobulin preparations. The values for all animals in a group were plotted and were found to be normally distributed. Student's t test was used for statistical evaluations.
1. Single-cell bronchial lymph node preparations exhibited very much the same cytokine profiles as peripheral blood mononuclear cells except for a lack of IL-8 production. 2. It should also be noted that the IL-8-positive cells almost exclusively belong to the monocyte cell population, while cells positive for γ-IFN and TNF-α fall in both gated cell populations. 3. The PMA and ionomycin treatment had a slight suppressive effect on IL-8 production by monocytes.
