Figure 2. Induction of cytokines by ITF I, in a dose range of 0 to 100 µg/ml.

Statistical significance levels were determined with a parametric Student’s t-test for unpaired observations (two-tailed). Mean and SEM of cytokine production is plotted as percentage of controls, which were set to 100% (n = 4). Panels A to F show the results for IL-1Ra, IL-1β, IL-6, IL-10, IL-12, and TNF-α respectively.
