Comparison of i.v. dosed BBB targeting hIgG1TM-IL-1RA fusions in reversal of mechanical hyperalgesia in the Seltzer model of neuropathic pain. Compares the effect of i.v. dosed BBB-IgG and BBBt0626-IL-1RA fusion antibodies on reversal of PNL induced mechanical hyperalgesia by following the ratio of pressure applied to ipsilateral and contralateral hind paws. Sham + Control 40 mg/kg (•), Op + control 40 mg/kg (♦), Op + PBS 10 mg/kg (▾), Op + BBB 40 mg/kg (▪) and Op + BBBt0626 40 mg/kg (▴). Sciatic nerve ligation surgery occurred at base (day 0) and IgG-IL-1RA fusion was administered 13 days post-surgery. Ipsilateral/contralateral ratio followed for a further 4 days. N = 10 per group. Data analyzed using 2-way ANOVA with time and treatment as dependent factors. Subsequent statistical significance obtained using Bonferroni's Post-Hoc test. **p < 0.01 to PNL/NIP-228/Kin control.
