IL-17A and IL-22 induce not only keratinocyte proliferation, but also tumor necrosis factor (TNF)-α, chemokine (C-X-C motif) ligand (CXCL)1 and CXCL8 production. TNF-α accelerates the infiltration of inflammatory cells, including lymphocytes, monocytes and neutrophils, from the peripheral blood into skin with dendritic cell activation.
