[Regulation of HDL lipoprotein plasma levels in relation to atherogenesis]
1Interní klinika FN, Praha-Motol.
Insights
High-density lipoprotein (HDL) cholesterol plays a key role in preventing atherosclerosis. This review details HDL metabolism and factors influencing its plasma levels, including lifestyle and genetics.
Area of Science:
- Lipid metabolism and cardiovascular disease research.
- Biochemistry of lipoproteins and their role in atherosclerosis.
Context:
- Atherogenesis, the development of atherosclerotic plaques, is significantly influenced by high-density lipoprotein (HDL) levels.
- Understanding HDL metabolism is crucial for developing targeted therapies against cardiovascular diseases.
Purpose:
- To review the metabolic pathways governing HDL lipoprotein synthesis and catabolism.
- To elucidate the internal and external factors that regulate plasma levels of HDL and its subclasses.
Summary:
- The review examines the intricate metabolic relationships of HDL lipoproteins, focusing on their synthesis and breakdown.
- It identifies key internal factors (genetics, sex, age, obesity) and external factors (diet, exercise, alcohol, smoking, drugs) affecting HDL levels.
Impact:
- Provides a comprehensive overview of HDL regulation, aiding researchers in understanding its role in atherogenesis.
- Highlights modifiable factors influencing HDL levels, offering insights for clinical interventions and lifestyle recommendations.
Abstract:
There is no doubt nowadays on the importance of HDL lipoproteins in atherogenesis. In the submitted review the author presents information on the regulation of HDL lipoprotein plasma levels and their sub-classes. First he deals with metabolic relations, in particular synthesis and catabolism of HDL lipoproteins. He mentions then factors which influence plasma levels of HDL lipoproteins and their sub-classes--external and internal factors. As to internal factors the author discusses genetic predisposition, sex, age, obesity, adipose tissue distribution; as to external factors the effect of diet, exercise, alcohol, smoking and drugs.
