sT_RM cells expanded after tumor rechallenge. (A) T cells infiltrate the skin after tumor rechallenge (n = 5). (B-E) The number of CD69⁺CD103⁻ activated T cells and CD69⁺CD103⁺ T_RM cells infiltrated in the skin (n = 5). (F-G) The representative results of skin infiltrating CD4⁺ and CD8⁺ T cells analysis by flow cytometry. (H-I) ELISA analysis of cytokines level in skin macroenvironment. An unpaired Student’s t-test was used. **p < 0.01, *p < 0.05. Error bars represent mean \(\pm\) SEM. See also Fig. S4.
