MUC2 and pancreatic intraductal papillary-mucinous neoplasm: We investigated how the known pathological phenotypic factors of IPMN, such as ductal involvement, subtype, expression of mucins (MUC1, MUC2, MUC5AC, MUC6) and CDX2, and invasiveness, are associated with the expression pattern of the NLRP3 inflammasome proteins.
