CCL7 and neoplasm: We have shown that mice immunized by bombardment of gold particles coated with plasmids encoding either of two chemokines – interferon inducible protein 10 (IP-10), or monocyte chemotactic protein 3 (MCP3) – fused with scFv, but not scFv alone, mounted protective antitumor immunity against a large tumor challenge (20 times the minimum lethal dose).
