Frequencies of peripheral blood Vδ1⁺ and Vδ2⁺ T cells in early- and late-stage breast cancer patients. a Dot plots of PBMC from breast cancer patients stained for expression of CD3 and Vδ1 or Vδ2. PBMC derived from 80 patients were analyzed by two-color flow cytometric analysis. Values shown are the percent of CD3⁺ T cells. Dot plots of three representative patients are shown (BC01: stage II; BC02: stage II; BC03: stage I). b Frequency of Vδ1⁺ and Vδ2⁺ T cells in early- (stage 0–II) and late-stage (stage III, IV) breast cancer patients. The percentages of Vδ1⁺ and Vδ2⁺ T cells were calculated based on the dot plots and are depicted in the scatter plots
