In the present study, we have investigated the expression of the cell-surface molecules CD11b, CD62L, CD18 and CD35 on resting and stimulated neutrophils, together with respiratory burst activity, myeloperoxidase and neutrophil elastase release, and IL-8 cytokine levels from blood cells in different categories of patients with asthma. Here, CXCL8 is linked to asthma.
