Figure 1.
Expression of both αd integrin (squares) and CD11b (circles) is upregulated rapidly in peripheral blood eosinophils incubated with PMA (50 ng/ml; filled symbols) but not with buffer alone (open symbols). Values are expressed as average MFI ± SEM, n = 3. Irrelevant isotype control antibody fluorescence (1.7 ± 0.2) was unchanged throughout these experiments. *P < 0.05 for treated vs. untreated samples.
