NFKB1 and acute pancreatitis: In keeping with this hypothesis, when we stained pancreata from wild‐type and Cxcr2−/− mice 24 h following induction of acute pancreatitis, we found occasional cells positive for nuclear NF‐κB‐p65, indicative of NF‐κB signalling, in wild‐type, but not in Cxcr2−/− pancreata.
