Effect of dexamethasone on TNF-α-induced IL-8 and GM-CSF release from eosinophils. Eosinophils were cultured with medium (control), or with TNF-α (20 ng/ml) (TNF-α) in the presence (Dexa) or absence (0) of dexamethasone (1 μM). IL-8 (A) and GM-CSF (B) release was evaluated by ELISA. Values are mean ± SEM (n = 5). *P < 0.05.
