Sex-opposed inflammatory effects of 27-hydroxycholesterol are mediated via differences in estrogen signaling.

ABSTRACT: Despite the increased awareness of differences in the inflammatory response between men and women, only limited research has focused on the biological factors underlying these sex differences. The cholesterol derivative 27-hydroxycholesterol (27HC) has been shown to have opposite inflammatory effects in independent experiments using mouse models of atherosclerosis and non-alcoholic steatohepatitis (NASH), pathologies characterized by cholesterol-induced inflammation. As the sex of mice in these in vivo models differed, we hypothesized that 27HC exerts opposite inflammatory effects in males compared to females. To explore whether the sex-opposed inflammatory effects of 27HC translated to humans, plasma 27HC levels were measured and correlated with hepatic inflammatory parameters in obese in
