Figure 3. Effects of Erk inhibitor on the KLH-induced NF-κB activation. THP-1 reporter cell was stimulated with 0.1 µg/ml LPS or 50 µg/ml KLH in the presence or the absence of 5 µM Erk inhibitor (Nimbolide). Values represent mean ± SD of six assays.

**Significantly different from values in the absence of the inhibitor, P < 0.0001 (one-way ANOVA and Student's t-test).
