A 1014 cells were injected in C57BL/6 female mice. Treatment of C57BL/6 mice with aCD40 (30 μg/mouse every 3 days, intraperitoneal) started at Day 10 post tumor cell inoculation. Analysis of CD40 levels by flow cytometry of CD45 + CD19 + B cells prepared from tumor samples at day 22 post-treatment ( n = 5 per group) using a one-sided Mann–Whitney U test. B Splenocytes were isolated from C57BL/6 mice by magnetic separation, serum-free starved for 4hrs, and stimulated with or without 12.5 μg/ml aCD40. After 4 days of culture, splenic B cells were isolated by magnetic separation and stained for flow cytometric analysis ( n = 6 per group). C , D Tumor volume of 1014 melanoma in C57BL/6 female mice. Treatment with 200 μg/mouse αPD1 (every 3 days, intraperitoneal), 100 μg/mouse αCTLA4 (every 3 days, intraperitoneal), 30 μg/mouse agonist CD40 (aCD40, every 3 days, intraperitoneal), or IgG control antibody, starts at day 10 post tumor cell inoculation.

F Flow cytometric analysis of CD45 + CD19 + B cells in the tumor microenvironment of 1014 melanoma after 3 weeks treatment of aCD40. Data were replicates from one experiment ( n = 5 mice per group). G C57BL/6 mice were intravenously injected with formalin-fixed 2 × 10 6 metastatic <t>B16F10-Luc2</t> cells via the tail vein. Splenic CD8 + T and total B cells were isolated by magnetic separation after 2 days of tumor antigen priming. Total B cells were stimulated with 12.5 μg/ml aCD40 for 2 days and CD11b + B cells were isolated by magnetic separation. CD8 + cytotoxic T cell killing assay were performed via co-culturing CD11b + B cells, CD8 + T cells and B16F10-Luc2 cells in the conditioned RPMI complete medium containing 0.5 μg/ml of IL-7, 30U/ml of IL-2, and CD3/CD28 Dynabeads at a bead-to-cell ratio 2:1. Dead cells were removed and the luciferase activity of remaining live tumor cells was quantified to calculate % inhibition of CTL killing capacity. ( n = 3 independent experiments).
