Effect of monocytes from UC patients on the polarization of CD4 + cells towards TH1/2/17 cells. A The proportions of Treg cells in CD4 + T cells in HC, UC and UD patients, CD4 + CD25 + CD127- in the box was defined as Treg cells in the CD4 + T cell population; B the proportions of Th1 cells in CD4 + T cells in HC, UC and UD patients, CD4 + IFN-γ + in the box was defined as Th1 cells in the CD4 + T cell population; C the proportions of Th2 cells in CD4 + T cells in HC, UC and UD patients, CD4 + IL-4 + in the box was defined as Th2 cells in the CD4 + T cell population; D the proportions of Th17 cells in CD4 + T cells in HC, UC and UD patients, CD4 + IL-17A + in the box was defined as Th17 cells in the CD4 + T cell population. HC: healthy controls, n = 9; UC: UC patients without symptoms of anxiety/depression, n = 9; UD: UC patients with symptoms of anxiety/depression, n = 12. *P < 0.05, **P < 0.01
