Supplementary figures 1-10. Figure S1. IL-2c increases conventional CD4 T cell in ascites three weeks after final IL-2c, but does not affect ascites Treg and effector T cell numbers at one week after final IL-2c administration. Figure S2. IL-2c treatment increases CD8+ central and effector memory T cells in the ascites, and central memory T cells in TDLN. Fig S3. Additional Treg phenotype in ascites and TDLN after IL-2c treatment. Fig S4. IL-2c directly inhibits Treg suppression specifically in the tumor microenvironment. Fig S5. IL-2 signaling is not impaired in TDLN after IL-2c treatment. Figure S6. Specific Treg depletion is highly effective against ID8agg. Figure S7. αCD25 attenuates IL-2c-induced tumor rejection and T cell function in ID8agg OC. Figure S8. IL-2c promotes intratumoral T cell infiltration. Figure S9. IL-2c reduces intratumoral Treg activation and functional molecules in B16 melanoma. Figure S10. IL-2c increases TIGIT+LAG-3+PD-1+ CD8+ T cells in B16 tumors.
