In this article [1], the representative images of CD4 and CD8 staining for tumor IHC were carelessly repeated in Fig. 8. The corrected Fig. 8 should have appeared as shown in this correction.

RRM2 silencing has anti-tumor effects and enhances CD8 + T cells infiltrations in Lewis mice model. Lewis mice were injected with LV-NC and LV-siRRM2 infected LLC cells. a The tumor volumes were measured every 3 days and depicted in the line chart. b, c Representative IVIS spectrum imaging for tumor-bearing mice. The fluorescence radiance comparison between LLC-LV-NC and LLC-LV-siRRM2 groups. d, e Representative fow cytometry of CD4 + and CD8 + T cells in spleens and tumors. Quantitative analysis of CD4 + and CD8 + T cells in spleens and tumors. f, g Representative image of CD4 and CD8 staining for spleens and tumors by IHC. Scale bar: 100 μm. *p < 0.05, **p < 0.01, ns: not significant
