Subpopulations of CD4-positive T cells in the blood. CD4⁺ blood lymphocytes were gated to analyze expression levels of interferon- (IFN-) γ, interleukin- (IL-) 4, and IL-17A by flow cytometry (a, b, and d). The ratio of IFN-γ- and IL-4-expressing T helper (Th) cells was calculated (c). (e) Percentage of CD4⁺CD25⁺Foxp3⁺ regulatory T cells (Treg) among CD4⁺ lymphocytes. Data are presented as the mean ± SEM. Significantly different from the sham group (). ^†Significantly different from the saline group ().
