Abstract:
Diseases such as atherosclerosis involve large blood vessel narrowing and hardening, an increase in activated and inflammatory cells, and an accumulation of lipids such as cholesterol. The farnesoid X receptor (FXR) is a recently identified steroid-like receptor. Bile acids are FXR ligands, which use FXR feedback to limit their own biosynthesis in the liver from cholesterol. FXR ligands have been proposed as novel targets in cardiovascular disease, as they affect lipid metabolism in the liver and gastrointestinal tract and lower circulating triglycerides and cholesterol. Recent evidence also suggests that FXR is expressed in the vasculature, implicating FXR as a novel potential 'direct' target for cardiovascular diseases. This review aims to introduce the FXR literature and discuss the mechanisms by which FXR may both directly and indirectly affect the progression of cardiovascular disease.
Insights
Farnesoid X receptor (FXR) ligands show promise for treating cardiovascular diseases like atherosclerosis. They impact lipid metabolism and may directly target vascular pathways, offering new therapeutic avenues.
Area of Science:
- Cardiovascular Science
- Endocrinology
- Metabolic Disease
Background:
- Atherosclerosis involves blood vessel narrowing, inflammation, and lipid accumulation.
- Farnesoid X receptor (FXR), a nuclear receptor, regulates bile acid synthesis.
- FXR ligands influence lipid metabolism and are explored for cardiovascular disease.
Purpose of the Study:
- To review the literature on FXR.

About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Antianginal Drugs: Calcium Channel Blockers and Ranolazine
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
