Progress in Study on Relationship between Autoantigens of PAB and Crohn 's Disease / 胃肠病学

It is reported that zymogen granule membrane glycoprotein 2 (GP2 )and CUB and zona pellucida-like domain-containing protein 1 (CUZD1 )are the major autoantigens of autoantibodies against exocrine pancreas (PAB).GP2 is mainly expressed in the pancreatic acinar cell and M cells in small intestine follicle-associated epithelium,and CUZD1 is mainly expressed in uterus,ovary and pancreatic acinar cell.PAB is a relatively specific antibody for Crohn's disease (CD).The article reviewed the progress in study on autoantigens of PAB in CD.
