Abstract

Psoriasis is a common, autoimmune, chronic inflammatory skin disease. It has been demonstrated that cutaneous T17 cells play an important pro-inflammatory role in the pathogenesis of psoriasis, through the production of various Th17-related cytokines. Our previous studies have demonstrated that CD30L/CD30 signal plays a pivotal role in the differentiation of CD4+ Th17 cells and Vγ6+γδ T17 cells in the gut-associated lymphoid tissues of mouse. However, its effect on the pathogenesis of psoriasis is unknown. Here, we fully prove that CD30L/CD30 signaling plays a novel protective role in the development of psoriasis in mice, through selective inhibition of CCR6 expression and Th17-related cytokine synthesis in the Vγ4+γδ T17 cell subset. Meanwhile, treatment with agonistic anti-CD30 mAb had a significant therapeutic effect on our psoriasis mouse model. Therefore, the CD30L/CD30 signaling pathway is an ideal target for antibody therapy, which may become a new approach for the immunobiological treatment of psoriasis.
