Ethyl Acetate Extract from Celastrus aculeatus Merr. Suppresses Synovial Inflammation in Adjuvant Arthritis Rats through Apoptosis Induction of CD4⁺CD25⁺FOXP3⁺ T Cells

Figure 3

Effects of EAE on peripheral regulatory T cells in AA rats induced by Mtb. After 28 days, rats were sacrificed. Blood from the abdominal aorta was incubated with PECy7-CD4, FITC-CD25, and PE-FOXP3 antibodies. The proportion of CD4⁺CD25⁺FOXP3⁺ T cells and CD4⁺CD25⁺ T cells in peripheral blood CD4⁺ T cells was detected by flow cytometry.
