Popis: | Interleukin (IL)-33 is a member of the IL-1 family, participating in both helper T1 (Th1)- and Th2-type immune responses, but its ambiguous effects on tumor growth and related immune mechanisms remain unclear. Here, we report that recombinant mouse IL-33 (mIL-33) significantly inhibited colon cancer growth and metastasis to lung and liver in a murine CT26 or MC38 tumor-cell engraftment model. This effect could be associated with CD4+ T cells and CD40 L signaling, as depletion of CD4+ T cells or blocking CD40 L signaling in vivo partly abolished the antitumor function of IL-33. In addition, IL-33 treatment upregulated CD40 L expression on tumor-infiltrating lymphocytes, and promoted the activation of CD4+ T, CD8+ T and natural killer cells via CD40 L signaling. Furthermore, IL-33 was sufficient to induce the ST2 expression on CD4+ T cells, but not on CD8+ T and natural killer cells, indicating that IL-33 acted on CD4+ T cells via a positive-feedback loop. Our findings shed new light on the IL-33-mediated antitumor effects and mechanisms of Th1 action, and also suggest that IL-33 may serve as an activator to boost anticancer immune responses in singular or combinatory therapies. |
