Foxp3 and IDO expression in the sentinel lymph nodes of breast cancer patients and controls. The expression of Foxp3 is shown as the median percentage of positive cells in the sentinel lymph nodes of breast cancer patients and controls (a), and of node-positive, node-negative breast cancer patients and controls (b). The expression of IDO is shown as the median percentage of positive cells in the sentinel lymph nodes of breast cancer patients and controls (c), and of node-positive, node-negative breast cancer patients and controls (d).
