Macrophage signaling lead to activation of CREB and AP-1 transcription factors. A Phosphorylation of CREB S133 and c-Jun S63 sites in primary human bronchial epithelial cells grown in ALI culture after 30 min of basolateral stimulation with vehicle media, LPS only or conditioned media from LPS activated alveolar macrophages from two lung resection tissue donors (d1, d2). B Quantification of mean pixel intensities from duplicate spots in each donor
