Abstract Title:
Formononetin ameliorates mast cell-mediated allergic inflammation via inhibition of histamine release and production of pro-inflammatory cytokines.
Abstract:
Various allergic diseases cause allergic inflammation, which is mediated by mast cells. The current study investigated the anti-allergic inflammatory effects of formononetin and its mechanism of actionusing mast cells. Levels of histamine and pro-inflammatory cytokines, including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6, were measured to assess the effects of formononetin on allergic inflammation. The activation of intracellular calcium and nuclear factor (NF)-κB, as well as the activity of caspase-1, were assessed to determine the mechanism of action. It was determined that difference concentrations of formononetin (0.1, 1 and 10 µM) suppressed histamine release and secretion of TNF-α, IL-1β and IL-6. Further investigations indicated that the effects of formononetin were associated with a reduction of intracellular calcium, suppression of NF-κB activation and upstream IκKα phosphorylation and inhibition of caspase-1 activity. Therefore, the results of the current study demonstrated that formononetin ameliorated mast cell-mediated allergic inflammation.
