Abstract Background Airway smooth muscle contributes to the pathogenesis of pulmonary diseases by secreting inflammatory mediators such as interleukin-8 IL-8 . IL-8 production is in part regulated via activation of Gq-and Gs-coupled receptors. Here we study the role of the cyclic AMP cAMP effectors protein kinase A PKA and exchange proteins directly activated by cAMP Epacl and Epac2 in the bradykinin-induced IL-8 release from a human airway smooth muscle cell line and the underlying molecular mechanisms of this response. Methods IL-8 release was assessed via ELISA under basal condition and after stimulation with bradykinin .
