Short-Chain Fatty Acids Suppress Inflammatory Reactions in Caco-2 Cells and Mouse Colons

Hung, Tran Van, Suzuki, Takuya·2018·Journal of Agricultural and Food Chemistry

Abstract

Short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate, play an important role in the maintenance of intestinal homeostasis. In the present study, anti-inflammatory effects of SCFAs were examined in human intestinal Caco-2 cells and mouse colonic cultures. Stimulation of Caco-2 cells with tumor necrosis factor (TNF)-α induced interleukin (IL)-8 (TNF-α, 17.1 ± 7.2 vs Control, 1.00 ± 0.26, P < 0.01) and IL-6 expression (TNF-α, 21.7 ± 10.0 vs Control, 1.00 ± 0.28, P < 0.01) through the activation of nuclear factor κB p65, spleen tyrosine kinase, and mitogen-activated protein kinase pathways. Pretreatment of cells with acetate (5 mM, IL-8 1.23 ± 0.40, IL-6 2.19 ± 0.92, P < 0.01 ), propionate (2.5 mM, IL-8 2.45 ± 2.10, IL-6 2.19 ± 0.92, P < 0.01), or butyrate (0.625 mM, IL-8 1.44 ± 0.70, IL-6 2.31 ± 0.32, P < 0.01) suppressed inflammatory responses induced by TNF-α. Pharmacological inhibition of monocarboxylate transporter (MCT)-1 attenuated the suppression of inflammatory signals by SCFAs. High expression levels of CXC motif chemokine ligand 2 (CXCL2, an IL-8 homologue, DSS, 31.7 ± 9.8 vs Control, 1.00 ± 0.70, P < 0.01) and IL-6 (DSS, 17.5 ± 7.2 vs Control, 1.00 ± 0.68, P < 0.01) were observed in BALB/c mouse colonic cultures exposed to dextran sodium sulfate, whereas treatments with mixtures of SCFAs decreased these elevated expression levels (CXCL2 4.14 ± 2.88, IL-6 0.58 ± 0.28, P < 0.01). Our results suggest that SCFAs transported by MCT-1 suppress TNF-α-induced inflammatory signaling in intestinal cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
