Background/Aims: Pancreatitis goes along with changes in exocrine enzyme synthesis and secretion in pancreatic acini. The multi-KH domain protein vigilin is supposed to play an important role in t-RNA trafficking especially in cells with high protein synthesis rates and may reflect the degree of stimulation of translational machinery during pathological processes. In relation to these phenomena we explored in this connection the impact of two different inflammation mediators in a system of isolated rat pancreatic acini. Methods: Acini were prepared from male Sprague-Dawley rats by collagenase digestion and incubated with mellitin or gamma interferon. Secretion and cytosolic cell content of pancreatic trypsin and amylase as well as the expression of vigilin were determined. Results: The phospholipase A2 activator mellitin caused morphological alterations and increased release of trypsin and amylase, while vigilin expression and the intracellular content of these enzymes decreased. Gamma-interferon, a cytokine which is involved at different steps in inflammation processes, selectively inhibits the release of trypsin(ogen) while not affecting amylase secretion and vigilin expression. Conclusion: Mellitin as well as gamma interferon causes alterations in pancreatic enzyme secretion. Additionally, mellitin seems to influence the expressed gene pattern of pancreatic acini while interferon-γ has no effect on protein synthesis but enzyme secretion.
