Formoterol- and epinephrine-attenuated cytokine production from DCs in a β 2 adrenergic receptor and dose dependent manner. BMDCs, 1.0 ± 106/ml in complete media, were stimulated by 10 μg HDM in the presence of various concentrations of FORM or epinephrine for 24 hours. Supernatants were collected, and concentrations of (a) IL-23, (b) IL-6 and (c) IL-10 were measured by ELISA. *p < 0.01, **p < 0.05.
