Figure 6. Skin IL-1 family cytokine levels after fracture.
IL-1β (A), IL-18 (B), IL-33 (C) and NGF (D) protein levels all increased in hindpaw skin at 4 weeks post-fracture but the increase in IL-33 did not reach significance. Systemic treatment with the SP NK1 receptor antagonist LY303870 for 8 days blocked the increased hindpaw skin expression of IL-1β, IL-18, and NGF after fracture. *p<0.05, **p<0.01 for fracture (n=8) vs control values (n=8). ###P<0.001, #p<0.05 for fracture (n=8) vs fracture+LY303870 (n=7).
