Figure 3From: Ambient particulate air pollution induces oxidative stress and alterations of mitochondria and gene expression in brown and white adipose tissues PM 2.5 exposure increases macrophage infiltration in the eWAT. A. Immunochemistry for macrophage-specific marker F4/80 in sections of eWAT from FA- and PM2.5-exposed mice. B. Quantification of adipose tissue macrophages in eWAT. n = 4. **P < 0.001 vs. FA. Arrow shows F4/80+ macrophages.Back to article page
