Summary

Story summary

Weill Cornell Medicine researchers identified free radicals in astrocytes as a potential contributor to dementia.
The study, published on November 4 in Nature Metabolism, found that blocking these radicals reduced inflammation and protected neurons.
The team developed S3QEL compounds to target harmful reactive oxygen species at mitochondrial sites.
In mouse models of frontotemporal dementia, S3QEL treatment decreased astrocyte activation and inflammatory gene expression, even after symptoms began.
