Intratumoral activation of tumor-infiltrating CD4⁺CD8⁺ T cells. (A) Representative image of immunofluorescence staining of the tumor sections from all groups showing infiltrated CD4⁺ T cells and CD8⁺ T cells. The nucleus were imaged at blue channel, CD4⁺ T cells were imaged at red channel, CD8⁺ T cells were imaged at green channel. Scale bar = 20 μm. (B) Quantification of fluorescence intensity of (A). Data are given as mean ± SD (n = 3). ∗∗∗P < 0.001.
