Insights

Failed atherosclerosis drug trials necessitate new screening models. Developing models that mimic human disease, including hyperlipidemia and inflammation, is key for effective anti-atherosclerotic drug discovery.

Area of Science:

  • Cardiovascular Research
  • Drug Discovery
  • Animal Models

Background:

  • Recent failures of cholesterol ester transfer protein (CETP) and acyl-CoA:cholesterol acyltransferase (ACAT) inhibitors highlight limitations in current anti-atherosclerotic drug development.
  • A revised approach is needed for screening and developing new anti-atherosclerotic drugs.

Purpose of the Study:

  • To emphasize the importance of understanding disease mechanisms within specific models.
  • To advocate for the development of advanced atherosclerosis models that incorporate hyperlipidemia, inflammation, and complications of diabetes and hypertension.
  • To highlight the need for multi-level analysis (in vivo, in vitro) of candidate molecules across atherosclerosis progression.

Main Methods:

  • Utilizing models that simultaneously exhibit hyperlipidemia, inflammation, and complications of diabetes and hypertension to better mimic clinical conditions.
  • Employing various cell-based and process-based models relevant to atherosclerosis.
  • Leveraging genomic sequencing, single nucleotide polymorphism (SNP) databases, and in silico quantitative trait loci (QTL) linkage analysis.

Main Results:

  • The study identifies the need for comprehensive models that recapitulate key features of human atherosclerosis.
  • It stresses the importance of analyzing therapeutic candidates across different stages and environments of the disease.
  • Genomic and computational tools offer potential for enhanced understanding and target identification.

Conclusions:

  • Developing sophisticated atherosclerosis models is crucial for effective anti-atherosclerotic drug screening.
  • Bridging the gap between small animal and human-like models is a significant challenge.
  • Genomic and in silico approaches hold promise for advancing atherosclerosis research and therapeutic target discovery.

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
