Liver X receptors (LXRs) are important regulators of cholesterol, fatty acid, and glucose homeostasis.
The Benefits of LXR
Low LXR activity is thought to be a cause of atherosclerosis.
Mice without LXRα are healthy when fed with a low-cholesterol diet. However, they develop enlarged fatty livers, degeneration of liver cells, high cholesterol levels in the liver, and impaired liver function when fed a high-cholesterol diet.
LXRs also regulate lipid homeostasis in the brain. Mice without LXR develop neurodegenerative changes in brain tissue.
LXR activators are effective for treatment in mouse models of atherosclerosis, diabetes, inflammation, and Alzheimer’s disease.
LXR activators lower cholesterol level in blood and liver. They improve glucose tolerance in mice by decreasing insulin resistance. In mice, they decrease amyloidal beta production in Alzheimer’s.
LXR activators were also shown to suppress the proliferation of prostate cancer and breast cancer cells as well as delay progression of prostate cancer .
LXR represses a set of inflammatory genes after activation by bacterial components or cytokines .
Less LXR is thought to play a causal role in Ulcerative Colitis .
Loss of LXR function compromised innate immunity in an animal model, which shows the importance of LXR for a normal functioning immune system .
LXR plays an anti-microbial role and protects against Tuberculosis .
LXR can help prevent amyloid beta formation, which causes Alzheimer’s .
The Negatives of LXR
LXR and Weight
It’s not clear exactly what the effect of Liver X Receptors (LXR) on weight is, but it has an effect depending on a variety of environments and factors.
Mice without LXR are resistant to certain protocols of diet-induced obesity, but they have shown increased fat tissue mass .
Over-expression and activation of LXRα in mouse white fat cells increased the release of free fatty acids. LXR activators increased free fatty acids in the blood, suggesting an increased release of fat from fat cells (dependent on the decreased PLIN1) .
Activation of LXR in white fat cells increased the expression of the enzyme (Elovl3) that correlates with fatty acid oxidation .
LXR activation shifts oxidation toward the utilization of fats instead of carbohydrates .
In contrast to findings in white fat cells, LXR prevents the oxidation and energy expenditure in brown fat cells .
In sum, while activation of LXR seems to increase fat oxidation in white fat cells, it suppresses energy dissipation in brown fat cells .

Inflammation blocks LXR production of genes. LXR inhibits Nf-kB.
LXR and PPAR gamma bidirectionally activate each other.
