Intracellular flow cytometry (Figures 2D–F) demonstrated a significantly higher percentage of IL-17-producing NKT cells in ARDS patients in comparison to HCs (median 24.1% vs. 3.50%, P < 0.005; Figure 2E), while the levels of IFN-γ+ and IL-4+ NKT cells did not differ significantly between the groups (Figures 2D, F). The gene discussed is IFNG; the disease is acute respiratory distress syndrome.
