Insights
High-density lipoprotein (HDL) plays a crucial role in preventing atherosclerosis by removing cholesterol and reducing inflammation. Research into HDL-related proteins may lead to new therapies for cardiovascular disease.
Area of Science:
- Cardiovascular Science
- Lipid Metabolism
- Molecular Biology
Background:
- Atherosclerosis is a major global cause of death, with increasing prevalence in Japan.
- High-density lipoprotein (HDL) is known for its protective role against atherosclerosis, attributed to reverse cholesterol transport and anti-inflammatory properties.
- Current HDL-modulating therapies for cardiovascular risk reduction are unavailable.
Purpose of the Study:
- To investigate the function of HDL-related proteins, including those regulating HDL production (ATP-binding cassette transporters) and HDL-binding proteins.
- To explore the potential of apolipoprotein A-I (apoA-I) binding protein (AIBP) in enhancing HDL function.
- To identify potential prognostic and therapeutic strategies for cardiovascular disease.
Main Methods:
- Focus on the function of HDL-related proteins.
- Investigate ATP-binding cassette transporters involved in HDL production.
- Analyze HDL-binding proteins and their role in HDL function.
Main Results:
- Apolipoprotein A-I (apoA-I) binding protein (AIBP) may enhance HDL function by promoting lipid release and reducing inflammation.
- Studies on HDL-related proteins provide insights into HDL's protective mechanisms.
- Research highlights the importance of HDL-binding proteins in cellular lipid regulation.
Conclusions:
- Understanding HDL-related proteins is crucial for developing novel cardiovascular disease therapies.
- Targeting HDL function presents a promising avenue for reducing atherosclerosis burden.
- Further research into HDL-binding proteins and their regulatory roles could yield significant clinical benefits.
Abstract:
Atherosclerosis is a vascular disease responsible for acute heart attacks and stroke, which are leading causes of death not only in industrialized countries but also worldwide, and the number of patients afflicted by this disease has been increasing in Japan. High-density lipoprotein (HDL) is the plasma lipoprotein that carries what is often called your "good cholesterol" through the blood. This good cholesterol moniker is associated with HDL because higher circulating levels of this lipoprotein are associated with a well-known reduction in the risk of arteriosclerosis. Moreover, many protective mechanisms by which HDL could reduce atherosclerosis are described, including reverse cholesterol transport, along with anti-oxidant, anti-inflammatory and anti-thrombosis activities. However, HDL-modulating therapies to lower cardiovascular risk are not yet available. It has recently been proposed that apolipoprotein A-I (apoA-I) binding protein (AIBP) enhances HDL function by accelerating lipid release from cells and reducing associated inflammatory processes. In this context, our research is focused on the function of HDL-related proteins, such as proteins that regulate HDL production (ATP-binding cassette transporters), and HDL-binding proteins. We expect that these studies could eventually help in the development of HDL-related prognostic and therapeutic strategies to reduce the burden of cardiovascular disease in the future.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
