  • FunctionAssociates with IL12B to form the IL-23 interleukin, an heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to an heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.
  • Tissue specificitySecreted by activated dendritic and phagocytic cells and keratinocytes. Also expressed by dermal Langerhans cells (at protein level).
  • Sequence similaritiesBelongs to the IL-6 superfamily.
  • Developmental stageExpressed by newborns dendritic cells.
  • Cellular localizationSecreted. Secreted upon association with IL12B.
  • Information by UniProt

Recombinant human IL23 protein images

  • IL17 secretion by Mouse splenocytes
    Mononuclear cells isolated from Mouse spleen were cultured with Mouse IL23 in presence or absence of various concentrations of ab109153 for 3 days. Levels of IL17 accumulated in culture supernatants were measured using ELISA.
