| Outline of Final Research Achievements |
Social mammals recognize and discriminate their conspecifics to make pair bonding, to maintain species, to create social hierarchy, and to live in the society to which they belong. We investigated whether kallikrein 8 (KLK8)-neuregulin1-ErbB4 signaling is crucial for the social behavior. Using social discrimination paradigm of a three chamber behavioral task, we found neuregulin1-deactivated mouse (klk8-knockout mouse) impaired social discrimination, while this mouse exhibited normal social approach. Intraventricular injection of NRG1 177-246 (active domain of neuregulin1) into the brain of klk8-knockout mouse recovered the impairment into the level of wild type mouse and thus, KLK8 is one of the key regulator through NRG1-ErbB4 signaling, and contributes to social discrimination behavior.
