Inhibiting LXRα phosphorylation in hematopoietic cells reduces inflammation and attenuates atherosclerosis and obesity in mice

Voisin et al. show that reducing phosphorylation at serine 196 of LXRα (LXRα pS196) in hematopoietic cells attenuates atherosclerosis and obesity of mice fed a high-fat diet. They find that the transcriptional activity of LXRα is reprogrammed in macrophages and T cells to promote an anti-inflammatory phenotype, thus identifying a functional role of LXRα pS196 in immune cells.
