Leucine supplementation decreases adipose tissue inflammation in Aymice. A: messenger RNA levels of aP2, leptin, monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor alpha (TNF-alpha), and F4/80, a macrophage-specific marker, in the epididymal adipose tissue of leucine-treated and control young Aymice at the end of 4 month study period. The expression levels in leucine-treated mice are expressed relatively to the levels of the control mice. * and ** indicate p < 0.05 and 0.01, respectively, control vs. leucine-treated, n = 8. B. Immunohistochemical staining of F4/80 of epididymal adipose tissue of leucine-treated and control young Aymice. The arrows indicate the nuclei positive for F4/80 staining.
