Figure Lengend Snippet: T26 enhances antitumor immunity through DC activation. (A) Experimental workflow for analyzing immune cell populations. C57BL/6 and BALB/c mice were subcutaneously inoculated with 1 × 10 6 MC38 and CT26 cells, respectively, into the right flank on day 0. Once tumors reached approximately 80 mm 3 , mice were randomly assigned to receive either JHU083 or MSA‐2 at 1 mg kg −1 day −1 or T26 at 1.5 mg kg −1 day −1 from day 7 to 11. After treatment, tumors, spleens, and draining lymph nodes were harvested for flow cytometry analysis. (B) Experimental design for ELISA quantification of pro‐inflammatory cytokines in serum and tumors in MC38 or CT26 bearing mice following PBS, JHU083, MSA‐2, or T26 treatment. (C) Flow cytometry analysis of mature DCs (CD80⁺CD86⁺) in MC38 tumors ( n = 3). (D) Flow cytometry analysis of CD8⁺ T cells (CD3⁺CD8⁺) in MC38 tumors ( n = 3). (E) Flow cytometry analysis of GZMB expression in tumor‐infiltrating CD8⁺ T cells in MC38 tumors ( n = 3). (F) Flow cytometry analysis of mature DCs (CD80⁺CD86⁺) in spleens ( n = 3). (G) Flow cytometry analysis of CD8⁺ T cells (CD3⁺CD8⁺) in spleens ( n = 3). (H) Flow cytometry analysis of mature DCs (CD80⁺CD86⁺) in TDLNs ( n = 3). (I–M) Tumor and serum levels of IFN‐α, IFN‐β, IFN‐γ, TNF‐α, IL‐6 in MC38‐bearing mice ( n = 3). (N) C57BL/6 mice with MC38 tumor were pretreated (i.v.) with either 5 mg per mouse of Cytc or PBS before other treatment and maintained the injection every other day for two weeks to deplete DCs. (O,P) Tumor growth of MC38 tumors in C57BL/6 mice with different treatment ( n = 6). Error bars represent means ± SD. Differences between groups were tested using one‐way ANOVA followed by Tukey's multiple comparisons test, or unpaired Student's t ‐test.
