FIGURE 1.

Functional influence of mAb C3H7 on adhesion of T84 cells to immobilized CD11b/CD18 (A and B) and PMN transmigration across epithelial monolayers (C–E) and acellular Transwell filters (F), respectively. The antibody concentrations are the same (20 μg/ml IgG). PMN migration across T84 monolayers in b-to-a direction (C), HT29 monolayers in b-to-a direction (D), T84 monolayers in apical-to-basolateral direction (E), and acellular Transwell filters (F) in response to n-formyl-methionyl-leucyl-phenylalanine were performed in the presence or absence of indicated concentrations of mAb C3H7 and control mAb C1F3, respectively. The data are presented as the means ± S.D. (n = 3).
