Figure 1. IL-17-induced neutrophil recruitment in CF.
Production of Interleukin (IL)-6, transforming growth factor (TGF)-β and IL-23 by airway dendritic cells (DC) following activation by bacterial pathogens promotes Th17 cell differentiation. The release of IL-17A and IL-17F from these cells acts on airway epithelial cells to release neutrophil chemokines IL-6. IL-8 and growth related oncogene (GRO)-α. ICAM-1, intracellular adhesion molecule-1; MPO, myeloperoxidase; MMP, matrix metalloprotease.
