Oxidized low-density lipoproteins and their contribution to atherosclerosis

Lipoprotein oxidation is a critical early stage in the development of atherosclerosis, a disease characterized by the formation of plaque in arterial walls. It has been well-established that the oxidation of low-density lipoprotein (LDL) is a key factor in the progression of atherosclerosis. Oxidized LDL (Ox-LDL) possesses a range of atherogenic properties, contributing to endothelial dysfunction, foam cell formation, and inflammation within the arterial wall. The interaction between Ox-LDL and specific receptors on endothelial cells plays a crucial role in these processes. In this article, we will discuss the oxidation of LDL and the pro-atherogenic role of Ox-LDL, we will delve into the different types of LDL receptors involved in the uptake and metabolism of LDL, with a focus on their role in atherosclerosis. We will explore the mechanisms by which native LDL (nLDL) and Ox-LDL interact with these receptors, leading to the development and progression of atherosclerotic plaques. Then we will go through more in-depth discussion to explore the intricate role of scavenger receptors in the uptake of oxidized low-density lipoproteins (Ox-LDL) and their significant contribution to the pathogenesis of atherosclerosis. Understanding the intricacies of these receptor-ligand interactions is essential for developing targeted therapeutic strategies to combat atherosclerosis and its associated complications.
