ABSTRACT Introduction Liver X receptors (LXRs) are master regulators of atherogenesis. Their anti-atherogenic potential has been attributed to their role in the inhibition of macrophage-mediated inflammation and promotion of reverse cholesterol transport. Owing to the significance of their anti-atherogenic potential, it is essential to develop and test new-generation LXR agonists, both synthetic and natural, to identify potential LXR-targeted therapeutics for the future. Areas covered This review describes the role of LXRs in atherosclerotic development, and provides a summary of LXR agonists and future directions for atherosclerosis research. We searched PubMed, Scopus, and Google Scholar for relevant reports, from last 10 years, using atherosclerosis, liver X receptor, and LXR agonist as keywords. Expert opinion LXRα has gained widespread recognition as a regulator of cholesterol homeostasis and expression of inflammatory genes. Further research using models of cell type‐specific knockout and specific agonist‐targeted LXR isoforms is warranted. Enthusiasm for therapeutic value of LXR agonists has been tempered due to LXRα-mediated induction of hepatic lipogenesis. LXRα agonism and LXRβ targeting, gut-specific inverse LXR agonists, investigations combining LXR agonists with other lipogenesis-mitigating agents, like IDOL antagonists and synthetic HDL, and targeting ABCA1, M2 macrophages, and LXRα phosphorylation remain as promising possibilities.
