Intrathecal injection of anti-MCP-1 neutralizing antibody attenuated mechanical allodynia in MTBP rats. (A) PWL and (B) TWL values were measured between days 1–18 after cell inoculation. Morphine was intrathecally injected between days 9 and 18 in all BM groups. A single intrathecal administration of anti-MCP-1 antibody (in groups BM+Ab and B+Ab), or control IgG (10 µg; in groups BM+IgG and B+IgG) was performed on day 15 after inoculation of Walker 256 cells. Values are presented as the mean ± standard error (n=8 rats in each group). ‘//’ in the x-axis indicates the time at which morphine administration was initiated. *P<0.05 vs. BM and BM+IgG groups. PWT, paw withdrawal threshold; TWL, thermal withdrawal latency; B, bone cancer pain group; BM, morphine tolerance and bone cancer pain group.
