Cytokine profiles induced by bacteria taken from each vessel of the CCS (with or without B. longum) after addition to Caco-2 cells at retention times of 60 and 20 h. (A) IL-6 and CCS. (B) IL-6 and CCS with B. longum. (C) IL-18 and CCS. (D) IL-18 and CCS with B. longum. (E) TNF-α and CCS. (F) TNF-α and CCS with B. longum. The results are mean values from three separate experiments plus standard deviations and are normalized against hBD-1. The asterisks denote significant differences from the control (C). Significant differences between vessels and retention times are indicated by arrows connecting bars. *, P ≤ 0.05; **, P ≤ 0.01; ***, P ≤ 0.001.
