FIG. 7.

Inhibition of adhesion or invasion of type II rFimA-MS by anti-integrin antibody. (A) Effects of anti-integrin antibodies on adhesion of type II rFimA-MS to HEp-2 cells. (B) Effects of anti-integrin antibodies on adhesion of type II rFimA-MS to HGF. Different concentrations of antibodies were added 30 min before the addition of rFimA-MS. The amounts of MS that adhered to or invaded cells are expressed as the areas in the field of a confocal microscope (magnification, ×400), and at least five fields were analyzed in each experiment. The values are means and standard errors of the means based on three individual experiments. An asterisk indicates that a P value is <0.01. IgG, immunoglobulin G.
