Summary

Story summary

Researchers Mathias Schmidt and Juan Pablo Lopez gave the FKBP51 inhibitor SAFit2 to mice during stress, preventing social-rank deficits childhood adversity normally causes in male offspring.
Treated offspring behaved socially like control mice raised without hardship.
Gene-activity analysis showed SAFit2 normalized the medial prefrontal cortex and nucleus accumbens, the most affected of six stress-related regions.
The drug was effective only when given during stressor.
The experiment used only male mice.
