While DENV–NS3‐specific T cells that produced a combination of CD107a/IFNγ/MIP‐1β were significantly higher in patients with DHF (P = .049), DENV–NS3‐specific T cells that produced TNF‐α alone was significantly higher (P = .02) in patients with DF (Figure 2A). This evidence concerns the gene KRAS and Dengue hemorrhagic fever.
