Figure 2. Flow cytometry analysis of CD4+CD25+Foxp3+ Treg cells and CD4+IL17+ T cells in HF patients and healthy controls. All of the values were gated on CD3+CD4+ T cells. The values shown in the each upper right quadrant represent the ratio of Treg cells (A) or Th17 cells (B) for the corresponding CD4+ cells. (C) The statistical histogram shows the changes in Tregs and Th17+ cells and the ratio of Treg/Th17 cells in HF patients and healthy controls.
