Mechanism of action

Ustekinumab binds to the p40 subunit shared by both IL-12 and IL-23, preventing these interleukins from activating T cells and other immune cells that drive inflammation. By inhibiting these pathways, it reduces pathogenic Th1 and Th17 cell differentiation and proliferation, thereby suppressing the inflammatory cascade underlying autoimmune and inflammatory diseases.
