Human IL-23R Cytokine-Binding Homology Region-Fc Fusion Protein Ameliorates Psoriasis via the Decrease of Systemic Th17 and ILC3 Cell Responses

Interleukin (IL)-23 is considered an effective therapeutic target for the treatment of psoriasis because of the crucial role of the IL-23/IL-17 axis in the pathogenesis of psoriasis, and it has recently been reported to be involved in ILC3 cell differentiation. In this study, we report that eukaryotically expressed rhIL23R-CHR/Fc, as an endogenous extracellular receptor analogue, could be a natural antagonist in an imiquimod (IMQ)-induced...
