Blocking C5aR signaling in combination with RT could produce synergistic effect in antitumor efficacy. (A) Mice were inoculated subcutaneously with LLC tumor cells and treated with 8 Gy of local RT daily for 3 times. After RT, mice were intraperitoneally injected with 5.0 mg/kg/day C5aR1 inhibitor (W-54011) every other day. (B) The body weight change of LLC tumor-bearing mice in RT+W-54011 group, RT group, W-54011 group and control group (n=4 or 5 mice). (C) Representative images of tumors from mice of every group collected on day 24. (D,E) Tumor growth kinetics and (F) tumor weight of LLC tumor-bearing mice in RT+W-54011 group, RT group, W-54011 group and control group (n=4 or 5 mice). *, P<0.05; **, P<0.01; ***, P<0.001; ****, P<0.0001.
