Type II innate lymphoid cells (ILC2s), as potential effector cells of IL-25, may contribute to the pathogenesis of CRSwNP. However, their specific role in nasal polyp (NP) tissues, particularly in Chinese patients, remains insufficiently understood.Methods: Nasal polyp (NP) tissue and turbinate mucosa (TM) were collected from 37 Chinese CRSwNP patients undergoing surgery. TM samples from 7 patients with pituitary tumors were used as controls. IL-25 expression, Th2 cytokines, phosphorylated STAT3 (p-STAT3), and ILC2 levels were assessed via immunohistochemistry, flow cytometry, and ELISA. Isolated ILC2s from NP tissues were stimulated with IL-25, with or without limonin treatment, to evaluate downstream cytokine production and STAT3 activation.Results: Compared to control TM, both NPs and TM from CRSwNP patients showed elevated IL-25 expression. NP tissues exhibited increased p-STAT3 levels and overexpression of Th2 cytokines. ILC2s were significantly more abundant in NPs and TM of CRSwNP patients. Upon IL-25 stimulation, NP-derived ILC2s produced higher levels of IL-5 and IL-13, accompanied by enhanced STAT3 phosphorylation. Limonin treatment significantly reduced both STAT3 activation and Th2 cytokine production in IL-25-stimulated NP tissues.Conclusion: ILC2s function as key effector cells of IL-25 in CRSwNP, promoting type-2 inflammation via the STAT3 signaling pathway. Limonin attenuates this response and may serve as a promising therapeutic agent for CRSwNP by targeting IL-25/STAT3-driven ILC2 activation.
