IL-23 is a pro-inflammatory cytokine such as IL-17 and IL-22that mediate the inflammation and Epidermal hyperplasia of psoriasis, IL-23 is heterodimer of a p40 subunit, the major regulator of the Th17 pathway in treating psoriasis .IL-23 is primarily produced by antigen-presenting cells and stimulates the differentiation of T cells to Th17 and Th22 cells, the stimulation leads to an increase in the release of IL-17 and IL-22 that mediate the inflammation and epidermal hyperplasia of psoriasis.

IL-23 antagonism inhibit the effect of cytokines that play an important role in regulation of the adaptive and innate immune systems also develop the treatment of moderate-to-severe plaque psoriasis such as such as IL-17A, IL-17F, IL-22 and TNF secreted by T cells, natural killer cells, type 3 innate lymphoid cells, neutrophils, and mast cells. Drugs targeting IL-23 include BI 655066, briakinumab, guselkumab, tildrakizumab, andustekinumab
