Figure Lengend Snippet: a Schematic illustration of the treatment and analysis schedule for mice bearing orthotopic LLC tumors. b – f Representative flow cytometric analysis profiles and relative quantifications of CD8 + T cells (CD45 + CD3 + CD8 + ) ( b ), Treg cells (CD45 + CD4 + FOXP3 + ) ( c ), MDSCs (CD45 + CD11b + Gr-1 + ) ( d ), IFN-γ-secreting CD8 + T cells (CD45 + CD3 + CD8 + IFN-γ + ) ( e ), and CD8 + T cell proliferation (CD45 + CD3 + CD8 + Ki67 + ) ( f ) within the TME following the indicated treatments. g – i Quantification of the infiltration of CD45 + immune cells ( g ), CD4 + T cells ( h ), and CD8 + T cells ( i ) into lung tumors using flow cytometry. j – n ELISA analysis of IFN-γ ( j ), IL-2 ( k ), IL-12p70 ( l ), TNF-α ( m ), and IL-10 ( n ) levels in lung tumors of mice following the indicated treatments. Flow cytometry gating strategies are shown in Supplementary Fig. . All data are from n = 5 mice and are presented as mean ± s.d. Statistical analysis was performed using one-way ANOVA with Bonferroni’s multiple comparisons test. P values as indicated. Source data are provided as a Source Data file.
Article Snippet: The isolated CD8 T cells were resuspended in RPMI 1640 supplemented with 10% FBS, 1% penicillin/streptomycin, and 0.1% 2-mercaptoethanol (Thermo Fisher Scientific) and then cultured in a 48-well plate pretreated with anti-mouse CD3 and CD28 antibodies (Bio X Cell).
