Mechanism of action

Ustekinumab binds to the p40 subunit shared by IL-12 and IL-23, preventing these cytokines from activating T cells and other immune cells that drive inflammation. By inhibiting these pathways, it reduces pathogenic Th1 and Th17 cell responses implicated in autoimmune and inflammatory diseases. This mechanism has proven effective in conditions like psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis.
