Figure 1. PBMCs from allergic asthma patients express high levels of LFA-1. PBMCs were isolated from whole blood by use of Ficoll hypaque density gradient separation and stained with antibody against CD11a. The samples were analyzed by flow cytometry. The percent of CD11a-positive cells (A) and MFI (geometric mean) of CD11a (B) were measured. The significance of the differences was determined by use of Student’s t-test.
