An important role of interleukin-10 in counteracting excessive immune response in HT-29 cells exposed to Clostridium butyricum

Background Clostridium butyricum has become increasingly important in preventing and treating intestinal inflammation. In the intestine it may increase the resistance of the gut to pathogen invasion via inducing the secretion of anti-inflammatory cytokines. Interleukin 10 (IL-10) plays a central role in preventing certain inflammatory diseases by down-regulating inflammatory cascades. In a previous study, we observed that the level of IL-10 mRNA was modulated by C. butyricum. The aim of this study was to investigate whether C. butyricum achieves its beneficial effects through IL-10.
