Rethinking Treatment Goals in Psoriasis: Leveraging IL-17 Inhibitors to Move Beyond Skin Clearance Toward PsA Prevention - Episode 6
Targeting IL-23 and IL-17 in Psoriatic Disease: Pathways to Inflammation Control and PsA Prevention
In this episode, the panelists focus on the IL-23 and IL-17 pathways and their influence on inflammation control and psoriatic arthritis (PsA) prevention. The experts explain that IL-23 sits at the top of the inflammatory cascade, driving Th17 cell activation and downstream cytokine release. They note that inhibiting IL-23 can lead to long-term immunologic remission and possibly modify PsA progression, given its infrequent dosing and favorable safety profile. The discussion compares IL-23 and IL-17 inhibition, highlighting that while IL-23 blockade targets disease upstream, IL-17 acts as the “enforcer” cytokine driving local joint and skin inflammation. The panelists review emerging data showing that dual inhibition of IL-17A and IL-17F, as achieved with newer biologics, may provide more robust and durable skin clearance than targeting IL-17A alone. They conclude that deeper inflammation control through these pathways could reduce PsA risk and sustain long-term disease remission.
