LXR regulation of adipose tissue inflammation during obesity is associated with dysregulated macrophage function.

Objective: Liver X receptors (LXRs) play essential roles in cholesterol homeostasis and immune response. In obesity, elevated cholesterol levels trigger proinflammatory responses; however, the specific contributions of LXRs to adipose tissue (AT) macrophage (ATM) phenotype and metabolic programming are not fully understood. In this study, we determine the role of LXR isoforms in diet-induced obesity AT inflammation and insulin resistance.
