We observed significant induction of IL-8, IL-13, IL-1β, and IL-6 in both HT-29 and Caco2 cell lines with wild-type 600239 infection (Fig. 4A through E and 5A through E); IFN-γ was significantly induced with wild-type infection in the HT-29 cells only (Fig. 4C). This evidence concerns the gene CXCL8 and infection.
