5">Administration of IL-24 increased the number of IFN-γ-producing CD8+T cell and especially enhanced the cytotoxicity of CD8+T cells.
The number and activity of CD8+T cells in TILs were increased, while the number of Treg cells in TILs was decreased greatly by IL-24.
5">The anti-tumor effect of IL-24 as an immunological regulatory molecule was dependent on CD8+T cells and not CD4+ T cells.
IL-24 promoted IFN-γ production via the CD8+ T cells and that IL-24 expression correlated inversely with metastasis and clinical tumor stages.
