In the present work, animal models as well as cell lines were used to characterize the molecular mechanisms involved in the inhibition of pro-inflammatory processes in intestinal epithelial cells, with especial emphasis in the downregulation of the nuclear factor kappaB signaling pathway. This study focused on cell activation induced by pro-inflammatory cytokines as well as both colitogenic and probiotic bacteria. Inhibitory mechanisms, including blockage of signal transduction events and abrogation of the recruitment of nuclear factors to chromatin, were shown for a variety of flavonoids and host-derived anti-inflammatory mediators, such as the prostanoid 15-deoxy-delta12,14-prostaglandin J2 and the suppressive cytokines transforming growth factor beta and interleukin 10.
