Abstract:
Interleukin-33 (IL-33) belongs to the IL-1 cytokine superfamily and plays a critical role in regulating immune responses and maintaining host homeostasis. IL-33 is essential for driving and enhancing type 2 immune responses and is closely associated with the pathogenesis of various inflammatory diseases, infections, and the progression and metastasis of cancers. This study aimed to provide an overview of the anti-tumor effects of IL-33 by examining its complex immunomodulatory functions within the tumor microenvironment and how it regulates immune cells to mediate these effects. We also provided perspectives on the pleiotropic roles of IL-33 in immunomodulation, its potential use in cancer immunotherapies, and possible adverse effects associated with its therapeutic application. Understanding these mechanisms is crucial for developing more effective IL-33-based diagnostic and therapeutic strategies.
