Butyrate Inhibits NF-κB Activation in Lamina Propria Macrophages of Patients with Ulcerative Colitis

The decrease in DAI and mucosal inflammation in butyrate-treated patients is associated with a reduction of NF-kappaB translocation in lamina propria macrophages. Since the inflammatory process in UC is mainly sustained by macrophage-derived cytokines, the known anti-inflammatory effects of butyrate may in part be mediated by an inhibition of NF-kappaB activation in these macrophages.
