Abstract

Insights

Liver X Receptors (LXRs) show anti-atherosclerosis effects by promoting cholesterol transport and reducing inflammation. New LXR modulators are needed to avoid side effects like increased triglycerides.

Area of Science:

  • Cardiovascular Science
  • Molecular Biology
  • Pharmacology

Background:

  • Atherosclerosis is a major risk factor for cardiovascular disease.
  • Liver X Receptors (LXRs) are implicated in regulating cholesterol homeostasis and inflammation.
  • LXR activation presents a potential therapeutic strategy for atherosclerosis.

Purpose of the Study:

  • To review the physiological roles of LXRs.
  • To examine the link between LXR activity and atherosclerosis.
  • To discuss the therapeutic potential of LXR agonists.

Main Methods:

  • Comprehensive MEDLINE database search using keywords: "liver X receptors", "LXRs", and "atherosclerosis".
  • Manual review of references from identified key articles.

Main Results:

  • LXRs (LXRalpha and LXRbeta) promote reverse cholesterol transport and possess anti-inflammatory properties.
  • LXRalpha regulates hepatic triglyceride synthesis; LXR activation can induce lipogenesis and hypertriglyceridemia.
  • First-generation LXR ligands increase hepatic lipogenesis and plasma triglycerides, necessitating new ligand designs.

Conclusions:

  • LXR beta-selective agonists offer a therapeutic avenue.
  • LXR modulators acting as agonists in macrophages and antagonists in the liver represent a promising approach to treat atherosclerosis and cardiovascular diseases.

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
