Summary

Story summary

Karolinska Institutet and Yale University researchers developed a molecular atlas of postnatal mouse brain development, showing developmental genes can be reactivated during neuroinflammation.
The study uses a novel spatial tri-omics technique that measures gene expression, epigenetic regulation, and protein synthesis.
Results indicate neuroinflammation can spread beyond local injury, suggesting an interregional signaling network.
The findings have implications for demyelinating diseases like multiple sclerosis by guiding therapies targeting reactivated developmental pathways.
