The percentage of CD69+ hILCs, when compared to that of the healthy donors (median 3.56, IQR 2.38 - 5.04), were significantly higher in both febrile DF (median 21.95, IQR 10.72 - 32.13, p < 0.001) and febrile DHF (median 21.55, IQR 12.58 - 33.05, p < 0.001) (Figure 2B, upper panel). This evidence concerns the gene CD69 and Dengue hemorrhagic fever.
