NFKB1 and pancreatitis: These results suggested that CARD9 participate in early inflammation of pancreatitis by activating NF‐κB and p38MAPK in peritoneal macrophages Meanwhile, co‐immunoprecipitation assays showed that CARD9 could form a CARD9/Bcl10 complex in peritoneal macrophages to activate the inflammation signalling pathways of NF‐κB and p38MAPK, consistent with previous reports on fungal and viral reactions.19, 20
