The central role of IL-23 in psoriasis has been elucidated as a result of the rapidly evolving understanding of the underlying disease pathogenesis.

In summary, the IL-23/T17 signaling pathway is central to the immunopathogenesis of psoriasis by stimulating the proliferation of IL-17-producing lymphocytes and sustaining the inflammatory milieu found in psoriatic plaques. IL‐23 is a key cytokine involved in protective immune responses to bacterial and fungal infections 59;. It is a heterodimeric cytokine consisting of a p19 subunit and a p40 subunit that is shared with IL-12, another cytokine implicated in the development of psoriasis.

Psoriasis is a chronic, inflammatory multisystem disease, which affects up to 3.2% of the U.S. In announcing the approval this morning, Janssen said IL-23 is a naturally occurring cytokine involved in normal inflammatory and immune responses associated with symptoms of psoriatic arthritis. Pivotal trials and postmarketing data also suggest that IL‐17 and IL‐23 blockers are safer than tumor necrosis factor alpha blockers.

Th17 lymphocytes are pathogenetic mainly through the release of their effector cytokine, interleukin 17.1 Although Th17 cells infiltrating psoriatic plaques release other pathogenetic cytokines.
