Summary

Story summary

Researchers identified how a Shank3 gene mutation disrupts vasopressin release, affecting social behavior in mice.
Vasopressin is essential for sociability and aggression, acting through AVPR1a and AVPR1b receptors.
Mutant mice exhibited reduced sociability and defensive aggression due to limited vasopressin in the lateral septum.
Activating AVPR1a enhanced social interaction without increasing aggression, indicating potential for autism therapies.
The study, funded by various organizations, was published in Nature Communications and may inform drug development.
