Figure 2. Changes of phenotype in CD4⁺CD25⁺ Tregs induced by APS.

The ratios of CD4⁺CD25⁺/CD4⁺, CD4⁺CD25⁺Foxp3⁺/CD4⁺, CD4⁺CD25^low/CD4⁺, CD4⁺CD25^high/CD4⁺ and Foxp3⁺/CD4⁺CD25⁺ of sham burn mice, burn control mice, burn plus P. aeruginosa and burn plus P. aeruginosa with APS (50,100, and 200 mg/kg) treatment on PBD 1, 3, 5 and 7 were detected with FACS analysis. * P<0.05 compared with the burn plus P. aeruginos group by the one-way ANOVA test. †P<0.05 compared with mice received APS (50 mg/kg) by the one-way ANOVA test.
