Figure Lengend Snippet: The treatment model with low-dose radiation in the mouse model. (A) Diagram of treatment procedures after LLC cell inoculation in mice. (B) Mice injected with LLC cells were categorized into control, MEKi, RT, and MEKi+RT groups, with tumor sizes measured on the left and right side. (C) Tumor growth curves for four groups. (D) Tumor weight comparison post-excision. (E, F) Flow cytometry analysis of CD8+ and CD4+ T lymphocyte proportions in infiltrating immune cells of the tumor on the left side. (G, H) Flow cytometry analysis of CD8+ and CD4+ T lymphocyte proportions in spleen cells. (I–L) Flow cytometry analysis of CD107a+, granzyme B, and IFN-γ+ CD8+ T lymphocytes and IFN-γ+ CD4+ T lymphocytes. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001. IFN, interferon; MEK inhibitor; RT, radiotherapy.
Article Snippet: The resultant cell suspension was either collected directly or isolated using the Mouse Tumor Infiltrating Lymphocyte Isolation Kit (Solarbio, Beijing, China; Cat. No. P9000) in accordance with the manufacturer’s protocol.
