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. Here, BCL10 is linked to pancreatitis.
