What is the mechanism of action of Abrocitinib?
Abrocitinib is an oral small molecule that selectively inhibits Janus kinase 1 (JAK1). JAK1 is a key mediator in the signaling pathways of several pro-inflammatory cytokines implicated in the pathogenesis of atopic dermatitis. By inhibiting JAK1, abrocitinib reduces the signaling of these cytokines, leading to a decrease in inflammation and immune cell activity associated with AD. [9]
The JAK-STAT pathway is crucial for the function of immune cells and the production of cytokines. In AD, overactive signaling through this pathway contributes to skin barrier dysfunction, inflammation, and the characteristic intense pruritus. Selective JAK1 inhibition aims to dampen these pathways with potentially fewer off-target effects compared to broader JAK inhibitors.
