Effects of β-Lapachone on the Production of Th1 and Th2 Cytokines in C57BL/6 Mice

In this study, we investigated the effects of β-lapachone (β-lap) on the production of cytokines in C57BL/6 mice. The culture supernatants of splenocytes exposed to β-lap plus lipopolysaccharide or concanavalin A (Con A) were harvested to determine Th1 (tumor necrosis factor-α, interferon-γ, interleukin [IL]-1β, IL-2, IL-17A, and IL-12) and Th2 (IL-4, IL-5, IL-6, and IL-10) cytokines. IL-2, a Th1 cytokine, was expressed at higher levels in...
