6) 🌟 Conclusion:

ELS impacts stress-related neurobiology differently in males & females.
HPA-axis dysregulation, altered fear memory, & brain metabolism may inform sex-specific interventions for stress-related disorders.
Check out the full study for details!

5) Brain metabolism alterations by ELS:

ELS altered purine & glutamate metabolism pathways in the BLA, dHIP, & vHIP.

Sex differences in these pathways might explain distinct behavioral outcomes.

Linking brain metabolism to stress response is key!

4) 🚀 Using the open-source package DeepOF, we performed unsupervised analysis of fear behaviors. This revealed novel sex-specific patterns, in which females showed more active fear response (darting-like behavior) via explorative behaviors, that males did not show.

3) 🔍 Fear memory formation is altered on freezing:

ELS exposure reduces freezing behavior during fear retrieval especially in males.

2) 🧬 We show that ELS affects HPA-axis regulation differently in males & females:

Females: Persistent body weight effects & elevated baseline CORT early on

Males: Altered adrenal weight & delayed recovery of HPA-axis function

Sex matters in stress response!

1) Early life stress (ELS) increases vulnerability to stress-related disorders, such as PTSD, often with sex-specific impacts. Using a mouse model, we explored how ELS alters:
- HPA-axis regulation
- Fear memory acquisition & retrieval using
- Brain metabolomic pathways

Sex-specific fear acquisition following early life stress is linked to amygdala and hippocampal purine and glutamate metabolism - Communications Biology This study models early life stress (ELS) to observe sex-specific effects on fear memory formation using innovative unsupervised classification together with cellular metabolism alterations in key str...

We've uncovered sex-specific effects of early-life stress (ELS) exposure on fear memory, HPA-axis regulation, and brain metabolism🧠. Unsupervised clustering shows that fear responses are more than only freezing.

Deep phenotyping reveals CRH and FKBP51-dependent behavioral profiles following chronic social stress exposure in male mice - Neuropsychopharmacology Neuropsychopharmacology - Deep phenotyping reveals CRH and FKBP51-dependent behavioral profiles following chronic social stress exposure in male mice

New paper from the lab, where we show how the co-chaperone and psychiatric risk factor FKBP5 acts in CRH-expressing neurons to shape stress- sensitive social behavior. Deep phenotyping using #DLC and #DeepOF was key to unravel these effects. www.nature.com/articles/s41...
