Summary

Story summary

PM2.5 exposure disrupts brown adipose tissue (BAT), increasing insulin resistance and revealing BAT vulnerability.
In a controlled mouse model, researchers exposed subjects to concentrated PM2.5 for 24 weeks.
The study links epigenetic changes in brown adipose tissue to HDAC9 and KDM2B, impairing metabolism and pointing to potential therapeutic targets.
The findings support policies to cut airborne pollutants.
