Using ELISA, we examined IL-17C protein expression in several Ps animal models of psoriasiform-like dermatitis, including the KC-Tie2 mouse model, the topical imiquimod treated C57BL/6 mice (35), the Klk6+ model (36), and a model in which Il17c is genetically overexpressed in KCs (8). This evidence concerns the gene TEK and skin disorder.
