96
Q

Ustekinumab (Stelara) MOA

A

Inhibits p40 subunit of the IL-12 and IL-23 cytokines.

IL-12 is also known as natural killer stimulatory factor or cytotoxic lymphocyte maturation factor. This cytokine is made up of a 40 kDA and a 35 kDA subunit—IL-12 p40 subunit is shared by IL-23.
• IL-23 plays an important role in inflammatory response
• In conjunction with other cytokines (IL-6, TGFβ) IL-23 stimulates naïve CD4+ T cells to differentiate into TH17 cells and TH22 cells, which are distinct from TH1 and TH2 cells.

TH17 cells promote the production of IL-17 which is a pro-inflammatory cytokine that enhances T cell priming and enhance the production of IL-1, IL-6, TNFα, and chemokines

It blocks the activation of PD-1 receptors through their ligand, PD-L1–Binding of PD-L1 to PD-1 receptors causes the inhibition of T cells
PD-1, then allows the immune response to be produced in the closed vicinity of the tumor

Immune checkpoint—functions as a negative feedback for immune response (downregulate immune response)
