Recombinant human tumour necrosis factor-alpha (rhTNF-α) stimulates IL-8 release from intestinal myofibroblasts. 18-Co human intestinal myofibroblasts were incubated with different concentrations of rhTNF-α or medium alone for 24 h. Supernatants were collected and analysed in triplicate for immunoreactive IL-8 protein by ELISA. *P < 0·05 compared with medium alone by Student's t-test. Similar results were obtained in a repeat experiment.
