Anti-hIL31RA antibodies attenuate scratching behaviors in human IL31-induced pruritus model
Anti-hIL31RA antibodies attenuate the scratching behaviors in IL31-induced murine pruritus model. Human IL31 was administered to the B-hIL31/hIL31RA/hOSMR mice (female, 12-week-old, 6 mice/group) to induce the scratching behaviors. Meanwhile, the mice were treated with nemolizumab analog (in-house) or PBS. Scratching behavior was recorded on day 1 (A), day 4 (B) and day 10 (C). Summary of the mouse Itching frequency in different groups shown in figure (D). As shown, IL31-treated mice show significantly increased scratching bouts. In the nemolizumab treatment group, blockade of IL-31 signaling with anti-hIL-31RA antibodies significantly attenuates scratching behaviors. Values are expressed as mean ± SEM. Significance was determined by the 2way ANOVA. (*P < 0.05, **P < 0.01, ***P < 0.0001)
