Differential regulation of LFA-1 and Mac-1 in lymphoid transfectants by SDF-1α. (A and B) Surface expression of LFA-1 and Mac-1 on Jurkat J-β2.7 transfectants. J-β2.7/αL and J-β2.7/αM transfectants were stained with mAbs to αL (TS1/22) or αM (CBRM1/29), respectively (solid line), and isotype control (dotted line). Shown is one representative experiment. (C–F) Adhesion of Jurkat J-β2.7 transfectants to ICAM-1. Cells were subjected to adhesion assays on ICAM-1 at 37°C with or without stimulation with PMA (100 ng/ml) for 30 min (C and D) or in the presence of SDF-1α (300 ng/ml) for the indicated periods (E and F). For mAb inhibition assays, cells were preincubated with saturating concentrations of mAbs for 30 min on ice. Data are mean ± SD of three independent experiments performed in triplicate. *, p < 0.05 versus unstimulated control.
