Up-regulation of C3H7 antigen on epithelial cells by pro-inflammatory cytokines. T84 monolayers cultured on Transwell inserts were treated with cytokines or left untreated. Surface binding of mAb C3H7 to control and cytokine-stimulated T84 monolayers was assessed by enzyme-linked immunosorbent assay after incubation for 48 and 72 h as detailed under “Experimental Procedures.” The data are presented as the means ± S.D. (n = 4). IFN, interferon.
