The fold change (FC) induced by different TLR agonists, calculated from the area under the curve for the <i>IL8</i> gene expression in a time course over 8 hours in healthy and polyp derived airway epithelium.

The value represents an average cumulative gene expression response to the TLR agonists in epithelial cells isolated from 6 healthy controls and 5 polyps with a standard deviation. Statistical significance comparing the differences in cumulative gene expression levels between normal or polyp epithelium is indicated as p value.
