LBP treatment prevented the increase of CD4+ CD25 high Tregs while promoted the infiltration of CD8+ T cells in tumor tissue. (a) Representative dot plots of CD4+ CD25 high Tregs percentages gated on CD4+ T cells in TDLN, spleen, and tumor tissue. (b) Statistical analysis of the percentage of CD4+ CD25 high Tregs in TDLN, spleen, and tumor tissue. (c) Immunohistochemical analysis of CD8 (red arrows) in the tumor tissue (magnification 200x). Data are represented as mean ± SD, in each group. versus model group. TDLN: tumor draining lymph node.
