ABSTRACT
Social behavior plays a significant role in the formation of social structure and population regulation in both animals and humans. Oxytocin (OXT) and its receptor (OXTR) are well known for regulating social behaviors, but their upstream regulating factors are rarely investigated. We hypothesized that the phosphorylation of the signal transducer and activator of transcription 3 (p-Stat3) may regulate social and aggressive behaviors via the OXT system in the nucleus accumbens (NAc). To test this hypothesis, OXT, p-Stat3 inhibitor, OXTR antagonist, and OXT plus p-Stat3 inhibitor were infused, respectively, into the NAc in the brain of male Brandt's voles (Lasiopodomys brandtii) - a social rodent species in grassland of Inner Mongolia, China. Our data showed that blockage of p-Stat3-Tyr705 signaling pathway in the NAc not only increased aggressive behavior but also impaired social recognition of male Brandt's voles via its effects on the expression of local OXT and OXTR. These results have illustrated a novel signaling pathway of p-Stat3-Tyr705 in regulating social behaviors via the OXT system.
