## In brief

- Researchers at the University of California, Riverside, report an explanation for why males and females respond differently to obesity.
- The study, published in PNAS Nexus, finds certain immune cell populations in fat tissue may protect against obesity-related inflammation while others may contribute to it.
- The source reports these findings as the study's explanation; no further quantitative details are provided in the available excerpt.

## Why it matters

Sex differences in how obesity affects the body could influence how obesity-related inflammation is studied and treated, and may point to immune cell populations as targets for future research.
