The Food and Drug Administration (FDA) have approved three types of IL-23 inhibitor for the treatment of moderate-to-severe psoriasis in adults. Guselkumab (Tremfya) Tremfya is a type of self. Therapies targeting either IL-23 or IL-17 have shown great efficacy in psoriasis and have helped augment our understanding of psoriasis pathogenesis. Therapies such as ustekinumab and guselkumab inhibit IL-23.
Ustekinumab targets the p40 subunit common to both IL-23 and IL-12 while guselkumab targets the p19 subunit found in IL-23. While antibodies to IL-12 and IL-23 have been approved in psoriasis treatment for several years, robust evidence on the key role of IL-23 has led to the newest class of biologics for the treatment. An anti-IL-12p40 antibody downregulates type 1 cytokines, chemokines, and IL-12/IL-23 in psoriasis. J Immunol. 2006 Oct 01;177(7):4917-26.

Guselkumab is a fully human monoclonal antibody that binds to the p19 subunit of IL-23. 9 Guselkumab was the first IL-23 antagonist to receive FDA approval for the treatment of moderate to severe plaque psoriasis in adults who are candidates for phototherapy or systemic therapy.
The monoclonal antibody was approved in 2017 based on results from 2 double-blind, placebo. Major advances have been made in the past 30 years in elucidating the pathogenesis of psoriasis, including the identification of T-helper 17 (Th17) lymphocytes as key players in psoriatic inflammation. 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. IL-12 is a heterodimer composed of a p40 and p35 subunit.
Research showed that the p40 subunit of IL-12 also paired with a unique p19 subunit. This new, additional cytokine was classified as IL-23, 11 and it was later discovered to play a more central role in psoriasis than IL-12. 9 Thus, research shifted from the inhibition of IL-12 to IL-23. Two approved and two pending anti-IL 23 drugs offer an opportunity for moderate to severe psoriasis patients to regain their lives, according to researchers presenting at.
The role of current biologic therapies in psoriasis predicates on the pathogenic role of upregulated, immune-related mechanisms that result in the activation of myeloid dendritic cells, which release IL-17, IL-23, and other cytokines to activate T cells, including helper T cell T H 17. Along with other immune cells, T H 17 produces IL-17. This proinflammatory cascade results in keratinocyte. The efficacy of interleukin (IL)-23 targeted drugs for the treatment of moderate to severe psoriasis found support in results from a meta-analysis published in Dermatologic Therapy.
Pooled outcome data from 14 randomized clinical trials revealed that guselkumab and risankizumab were associated with the greatest improvements in psoriasis area and severity.
