As previously reported [19], the content in both CD3+ and FOXP3+ T lymphocytes was higher in TN (median FOXP3+ cells/mm2 = 22.9) and HER2 (median FOXP3+ cells/mm2 = 23.8) BC than in LumA (median FOXP3+ cells/mm2 = 7.7) BC (Supplementary Figure S1D,E). This evidence concerns the gene FOXP3 and breast cancer.
