Systemic inflammatory toxicity mainly derived from IL-2-Fc rather than anti-CD137. Groups of C57Bl/6 mice (n = 4/group) were inoculated with 5 × 105 B16F10 tumor cells s.c. on day 0, then received i.v. injections of αCD137 and IL-2-Fc (αCD137/IL-2-Fc), Lipo-IL-2-Fc mixed with αCD137 (Lipo-IL-2-Fc/αCD137), or Lipo-αCD137 mixed with IL-2-Fc (Lipo- αCD137/IL-2-Fc) on day 8. One day later, sera were collected from peripheral blood and levels of IFNγ (a), IL-6 (b), MCP-1 (c) and TNFα (d) were assayed by luminex assays. All measurements shown are mean ± s.e.m.
