Outline of Final Research Achievements |
We show evidences that constitutive existence of IL-27 controls threshold of sensation that induce aversive behavior in physiological and pathological conditions. Mice lacking IL-27 signaling possessed chronic pain-like hypersensitivity without any treatments. Reconstitution of IL-27 in these mice reversed hypersensitive threshold of aversive behavior. Furthermore, these mice showed additional hypersensitivity when subjected to commonly used chronic pain models suggesting that the mechanism of hypersensitivity induced by ablation of IL-27 signaling was different from ones underlying known chronic pain models.
