Summary
This review explores how advanced transcriptomic technologies, like single-cell RNA sequencing, help unravel the complex neurobiology of stress adaptation. It highlights challenges and future directions for understanding stress responses and psychiatric disorders.
Area of Science:
- Neurobiology
- Genomics
- Psychiatry
Background:
- Excessive or chronic stress is linked to most psychiatric disorders.
- Understanding the neurobiology of stress adaptation is crucial but challenging.
- Transcriptomic methods offer new insights into stress responses.
Purpose of the Study:
- To review technologies for studying the stress transcriptome.
- To identify key questions regarding stress heterogeneity.
- To explore how different data types can be integrated.
Main Methods:
- Review of high-throughput transcriptomic technologies (e.g., single-cell RNA sequencing).
- Analysis of postmortem transcriptome studies and preclinical animal models.
- Discussion of integrating genomic, neuroimaging, and other datasets.
Main Results:
- Transcriptomic approaches are advancing the study of stress neurobiology.
- Converging evidence from studies points to common molecular pathways for stress adaptation.
- Methodological and analytical advances are improving our understanding.
Conclusions:
- Integrating diverse datasets is key to a comprehensive understanding of stress.
- Further research is needed to unravel shared and separate transcriptional programs for stress adaptation.
- This work provides a framework for stress neurobiologists and those applying transcriptomic approaches.
