Peritoneal adhesions are fibrous tissues formed after surgery. Both cytokines and transforming growth factors (TGFs) are involved in this process. The objective of this study was to investigate the cross talk between these entities. Peritoneal drainage fluid after surgery from patients and rodent models was examined by enzymelinked immunosorbent assay and fluorescence-activated cell sorter. Data showed that the concentrations of interferon (IFN)-gamma and interleukin (IL)-17 reached their peaks 6-12 hours after surgery, whereas TGF-beta 1 concentrations showed two postoperative peak time points at 2 and 72-96 hours. By neutralizing IFN-gamma, IL-17 6-12 hours, and TGF-beta 1 72-96 hours after surgery, the degree of adhesion reduced significantly. However, neutralizing TGF-beta 1 2 hours after surgery did not affect adhesion formation. Furthermore, in vitro studies showed that compared with the fibroblasts that were directly stimulated with TGF-beta 1, the prestimulation of IL-17 promoted plasminogen activator inhibitor-1 production while inhibiting tissue-type plasminogen activator production. Moreover, additional stimulation with IFN-gamma enhanced this effect. Together, these data indicate that IL-17 may promote adhesion formation by increasing the reaction of fibroblasts against TGF-beta 1. Blocking IL-17 might have a therapeutic potential in preventing adhesion formation after surgery.
