Ustekinumab was generated via recombinant human IL-12 immunization of human Ig (hu-Ig) transgenic mice. Ustekinumab binds to the p40 subunit common to IL-12 and IL-23 and prevents their interaction with the IL-12 receptor β1 subunit of the IL-12 and IL-23 receptor complexes.
What is the role of IL-23?
Interleukin-23 (IL-23) is a member of the IL-12 family of cytokines with pro-inflammatory properties. Its ability to potently enhance the expansion of T helper type 17 (Th17) cells indicates the responsibility for many of the inflammatory autoimmune responses.

IL-23 functions in innate and adaptive immunity, and is a key cytokine for promoting inflammatory responses in a variety of target organs. The most important function ascribed to IL-23 is its role in the development and differentiation of effector Th17 cells via activation of STAT3.
What produces il17?
