FOXP3 and neoplasm: The expression of FOXP3+ Treg in the tumor microenvironment and the main inhibitory factors in the peripheral blood across different mouse groups: The results (Figure 10) show that the proportion of Treg cells (7.02% ± 0.45%), TGF-β1 (547.84 ± 7.25 pg/mL), and IL-10 (127.21 ± 2.07 pg/mL) in the model group were at the highest levels compared to the other groups.
