Inhibition of IL-8 secretion by nCUR versus sCUR. IL-8 secretion by Detroit cells preincubated for 0, 15, 30 or 60 minutes with nCUR (green) or sCUR (red) and subsequently infected for 4 hours with live M. catarrhalis strain 25238 (MOI 100). □ indicates the positive control (0 μM CUR, MOI 100). (200 μM nCUR, MOI 0) and ■ (200 μM sCUR, MOI 0) are negative controls. At no time point there is was a statistically significant difference between nCUR and sCUR for a given concentration.
