Characterization of the interleukin-17 isoforms and receptors in lesional psoriatic skin

This study characterizes the mRNA profile of the IL-17 isoforms and receptors in psoriatic skin lesions. Furthermore, we demonstrate for the first time augmented protein levels of IL-17A, IL-17C and IL-17F in psoriatic skin lesions, indicating a possible role for IL-17C in addition to IL-17A and IL-17F in the pathogenesis of psoriasis.
