Figure 1. Nasal polyp tissue (n = 9) was pre-incubated with FF or MF at different concentrations for 1 hour and consequently stimulated with SEB for 24 hours (pre-challenge incubation).

% inhibition of cytokine release was calculated at a fixed concentration of 10⁻¹⁰ M; FF had a significantly higher suppressive effect on IFN-γ, IL-2 and IL-17 release vs. MF.
