Comparison of the CD69 expression of peripheral blood eosinophils with BALF eosinophils after SAP. Purified eosinophils (0.5 × 105/ml) of peripheral blood obtained from healthy donors or from asthmatics 10 min before and 18 h after SAP and BALF eosinophils from asthmatics obtained 18 h after SAP were incubated with 50 ng/ml NGF, BDNF, NT-3, or NT-4, respectively, or with cell culture medium alone (control). After 4 h, the CD69 expression was measured by flow cytometry. The figures show representative histograms of at least four independent experiments.
