Zymosan- or thioglycollate-induced experimental peritoneal inflammation in mice may serve as a convenient model for investigations of involvement of opioid peptides derived from exudatory leukocytes in the inflammatory processes. During peritonitis, the influx of neutrophils and monocytes/macrophages correlated with a sequential appearance of proinflammatory cytokines (IL-1beta and TNFalpha). After both kinds of stimulation, the expression of PENK mRNA was much higher in exudatory peritoneal leukocytes than its basal level in steady state.
