A, Experimental design of the study. When MCa-M3C tumors
reached ~100 mm3, mice underwent ExTr (60% of Vmax ExTr, for
14 days) or kept sedentary and were treated with anti-PD-1 plus anti-CTLA-4
(ICB) or isotype control IgG (i.p., every 4 days; black arrow heads).
B, ICB effects on tumor volume. C, The effect of
ExTr on MCa-M3C tumor growth with ICB. D–I,
TCR+CD8+ T-cell infiltration and function. (D)
Relative and (G) absolute numbers of CD8+ T cells. (E) Relative and
(H) absolute number of granzyme B+CD8+ T cells. (F)
Relative and (I) absolute number of IFNγ+CD8+ T
cells with ICB and ExTr. Statistical differences by (B, D-F) one-way or (C)
Two-way ANOVA, or (G-I) Kruskal-Wallis test. n=7-16 mice per group, pooled data
from 2-3 independent experiments. Data presented as mean ± SEM or median
± interquartile range and distribution (violin plot, G-I).
