Schematic representation of IL-12 and IL-23, and their receptors and downstream signaling pathways.
Cua and colleagues discuss the cellular and molecular rationale for targeting IL-12 and IL-23 for therapeutic purposes in inflammatory diseases; they also review existing clinical data, discuss potential side effects, and propose future directions for targeting these cytokines in additional disorder…

IL23 is an upstream cytokine in the Th17 axis, while IL12 is part of the Th1 immune response.
Immune diseases and Infections are seldom neatly partitioned into a specific T-helper dysfunction or response.

Ustekinumab, which targets both IL12 and IL23, may prove particularly useful in the treatment of certain diseases with considerable Th1-Th17 interplay.


The heterodimeric cytokines IL-12 and IL-23 play a key role in T helper cell and innate lymphocyte cell differentiation and expansion. They are composed of…
