Oxytocin (OT) plays a key role in the process of labor. This study investigates the effect of IL‐1β and IL‐6 on intra‐and extracellular OT in human smooth muscle cells and evaluates IL‐1β induced changes in IL‐6 production.

Intra‐ and extracellular OT peptide concentrations were measured by radioimmunoassay and IL‐6 mRNA and protein were evaluated by reverse transcription polymerase chain reaction and enzyme‐linked immunosorbent assay. RESULTS: Both, IL‐1β and IL‐6 led to an increase in OT secretion, which was accompanied by a reduction of the intracellular OT peptide pool. IL‐1β significantly induced IL‐6 mRNA expression and protein secretion, which did not further enhance IL‐1β induced OT secretion.
