Effect of EhJAB1 binding on EhMIF activity. (A) EhJAB1 inhibits EhMIF interaction with the human MIF receptor CD74 by GST pull-down competition assay. Input (lane 1) and GST control (lane 2). EhMIF was preincubated with or without EhJAB1 at increasing doses before mixing with GST-CD74 (lanes 3–6). (B,C) EhJAB1 inhibits EhMIF-induced IL-8 production in a dose-dependent manner. Human colonic epithelial cells HCT116 and Caco2 were incubated with EhMIF with or without EhJAB1 at increasing doses. Culture supernatants were collected after 8 h and IL-8 was quantified by ELISA. Data represent mean and SD of triplicates from 1 experiment and are representative of 3 independent experiments. *P < 0.01; **P < 0.001. ns, not significant.
