FIG 5 .
Immunomodulation capacities of F. prausnitzii supernatant and identified molecules in vitro. IL-8 production in TNF-α-stimulated HT-29 cells is shown. Experiments were done in triplicate. Results are expressed as picograms of IL-8 per milligram of protein and have been normalized with the IL-8 produced after the coincubation with PBS or LYBHI medium. SN, F. prausnitzii supernatant (20%). ***, P ≤ 0.001.
