At day 0, after stimulation, the percentage of IFN-γ+ iNKT cells of patients with DF (16.35%; 14.40–24.93%) and DHF (11.95%; 6.77–18.30%) were lower than those of healthy control (32.1%; 25.90–40.70%) (p = 0.002 and p = 0.01, respectively) (Figure 3c). The gene discussed is IFNG; the disease is dengue disease.
