The effect of CD4⁺CD25⁺ T cell depletion from LN cells of dual APL-treated mice on the secretion of TGF-β and IFN-γ. LN cells of the tested mice (5 × 10⁶ cells per ml) were stimulated with p195–212 (5 μM) for 48–72 h. Supernatants were collected, and the concentrations of TGF-β (A) and IFN-γ (B) were determined by ELISA.
