Figure 6. T regulatory cell depletion in combination with chemotherapy extends survival.
Percent survival of CC10-TAg mice treated with control IgG or αCD25 mAb as monotherapy, or in combination with 50 mg/kg carboplatin (CBDCA). Dosing strategy is shown above the survival graph. Mice received control IgG or αCD25 mAb from 8 weeks of age until end-stage determined by 15% weight loss. Carboplatin was administered in 3 doses, 5 days apart, commencing at 13 weeks. Over 15 cohorts of mice were treated to obtain 10∓16 mice per group. p<0.05, control versus CBDCA alone; p<0.05, CBDCA alone versus αCD25/CBDCA.
