Figure 3.
Mechanical allodynia was assessed in mice that were untreated (DMM), treated with IgG2c isotype control mAb (+IgG2c), or treated with ADAMTS-5 mAb (+anti-ADAMTS-5) through 16 weeks after surgery (A). A decrease in withdrawal threshold from the baseline at time 0 indicates development of mechanical allodynia. A subset of mice (n=5) was tested 24 hours after the first injection to rule out an acute analgesic effect (B). mean+95%CI. DMM+anti-ADAMTS-5 vs DMM: +7 weeks, p=0.0051; +9 weeks, p=0.0001; +11 weeks, p=0.0109. DMM+anti-ADAMTS-5 vs DMM+IgG2c: +7 weeks, p<0.0001; +9 weeks, p<0.0001; +11 weeks, p=0.0024; black vs DMM; grey vs DMM+IgG2c.
