Purpose of review: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory disorder with a poorly understood pathophysiology. Recent findings show that epithelial-derived cytokines, including thymic stromal lymphopoietin, IL-33, and IL-25, can exacerbate Th2 immune responses, ultimately leading to recalcitrant chronic rhinosinusitis and nasal polyps. Although IL-25 is increased in CRSwNP, the targeting of IL-25 as a therapeutic strategy remains largely unexplored. In this review, we outline the many recent advances in our understanding of the association between IL-25 and CRSwNP.
