Outline of Final Research Achievements |
This study was performed to reveal the role of cholecystokinin (CCK), a gastrointestinal hormone, in itch associated with atopic dermatitis. Pharmacologically, our behavioral analyses showed that intrathecal injection of sulfated CCK8 (CCK8S) induced alloknesis via the spinal CCK2 receptor (CCKR2). Thus, we developed a model of alloknesis, and these data suggest that the CCK8S/CCK2R system is involved in induction of alloknesis in mice.
