The Fas/Fas ligand (FasL) system is suggested to be correlated to the onset of inflammation and apoptosis in various diseases. However, whether Fas and FasL are expressed in chronic pancreatitis is unknown. The aim of this study was to examine the expression of the Fas/FasL system and to analyze its correlation with apoptosis in a spontaneous chronic pancreatitis model (the WBN/Kob rat). Four-week-old male WBN/Kob rats were fed a special pellet diet (MB-3). Different groups of rats were killed every four weeks, and pancreata were histopathologically examined. Fas and FasL mRNAs in the pancreas were detected with a reverse transcription-polymerase chain reaction method. The cellular localization of Fas and FasL mRNA and protein was determined with in situ hybridization (ISH) and immunohistochemistry (IHC). Apoptosis was detected with a terminal deoxynucleotidyltransferase-mediated method. Fas and FasL mRNA were expressed when the pancreas was still pathologically normal, and showed a biphasic peak at 12 and 20 weeks. ISH and IHC confirmed that Fas and FasL are expressed in the cytoplasm of acinar cells, ductal cells, and lymphocytes. An apoptotic index in acinar cells correlated to the expression of Fas and FasL mRNAs. These results suggest that the expression of the Fas/FasL system is involved in acinar cell apoptosis and the onset and progression of chronic pancreatitis in the WBN/Kob rat.
