Supplementary Figures 1 through 8 from A Multifunctional Role for Adjuvant Anti-4-1BB Therapy in Augmenting Antitumor Response by Chimeric Antigen Receptor T Cells

Supplementary Figure S1. Expression of activation and memory markers on transduced mouse T cells. Supplementary Figure S2. CAR T cell cytotoxic responses are not modulated by anti-4-1BB mAb therapy. Supplementary Figure S3. Her2 expression level on the mouse breast cancer cell line e0771-Her2 is comparable to the Her2-overexpressing human breast cancer cell line SKBR3. Supplementary Figure S4. Tumor weight is significantly reduced following CAR T cell and alpha-4-1BB therapy. Supplementary Figure S5. Anti-4-1BB therapy does not modulate the frequency of transferred or endogenous CD8+ tumor-infiltrating T cells. Supplementary Figure S6. Anti-4-1BB therapy modulates the frequency of mature dendritic cells in tumors and draining lymph nodes. Supplementary Figure S7. Anti-4-1BB does not modulate the frequency of MDSCs and DCs in RAG -/- mice. Supplementary Figure S8. Anti-4-1BB therapy drives maturation of NK cells.
