IL17A and infection: To fight infection, IL-17 potentiates granulopoiesis and neutrophilia through the release of granulocyte monocyte colony stimulating factor (GM-CSF) and induces neutrophil influx through the release of neutrophil chemoattractants such as IL-8, C-X-C Motif Chemokine Ligand 8 (CXCL8) [10].
