LCN2 and Erythema: In addition to markedly exacerbated erythema and scaling in IMQ-treated murine skin, LCN2 increased the mRNA expression of interleukin (IL)-17A, IL-17F, IL-22, IL-23, CC-chemokine ligand (CCL)20, TNF-α, chemokine (C-X-C motif) ligand (CXCL)1, CXCL2, LCN2, and S100A7 while it did not affect the mRNA levels of IFN-γ, or CXCL10 in the skin.
