Background: Atherosclerosis is an arterial blood vessel disease that begins and progresses by turning macrophages into foam cells. Uptake of oxidized low-density lipoprotein (ox-LDL), cholesterol esterification and cholesterol efflux are the most important factors in the formation of foam cells and play an important role in atherosclerosis.
Methods: The present study is based on the data obtained from the PubMed database (1961-2024) using the MeSH search terms "Atherosclerosis", "Macrophages" and "Foam cells". Reviews for writing the main text and non-English-language articles were excluded.
Result: The interaction between ox-LDL and macrophages plays an important role in plaque initiation and promotion processes. Macrophages abnormally digest ox-LDL, resulting in the accumulation of lipids and formation of foam cells. This is an important step in the development of atherosclerosis. Also, several other factors such as inflammatory factors, growth factors, hormones, etc. can play an important role in the development of atherosclerotic lesions or counteract it by affecting the formation of foam cells.
Conclusion: Several factors can affect the progression of atherosclerosis by affecting macrophage activity or its conversion to foam cells. Also, some of these factors play a protective role against the development and atherosclerosis progression. In this paper, we reviewed some of these factors and their effect on atherosclerosis.

Osteoarthritis, a major global cause of pain and disability, is driven by the irreversible degradation of hyaline cartilage in joints. Cartilage tissue engineering presents a promising therapeutic avenue, but success hinges on replicating the native physiological environment to guide cellular behavior and generate tissue constructs that mimic natural cartilage. Although electrical stimulation has been shown to enhance chondrogenesis and extracellular matrix production in 2D cultures, the mechanisms underlying these effects remain poorly understood, particularly in 3D models.

OxLDL is increased during aging and stimulates monocyte transformation into foam cells and induces metabolic reprogramming and pro-inflammatory responses, accelerating atherosclerosis progression and contributing to other age-related diseases. This study investigated the effects of Mdivi-1, a mitochondrial fission inhibitor, and S1QEL, a selective complex I-associated reactive oxygen species (ROS) inhibitor, on OxLDL-induced responses in monocytes.

The accumulation of oxidized low-density lipoprotein (oxLDL) in macrophages leads to the formation of foam cells and atherosclerosis development. Reducing the uptake of oxLDL in macrophages decreases the incidence and progression of atherosclerosis. Four distinct single-strand DNA sequences, namely, AP07, AP11, AP25, and AP29, were selected that demonstrated specific binding to distinct regions of oxidized apolipoprotein B100 (apoB100; the protein component of oxLDL) with low HDOCK scores.

DNA methylation modifications are an important mechanism affecting the process of atherosclerosis (AS). Previous studies have shown that Galectin-8 (GAL8) DNA methylation level is associated with sudden death of coronary heart disease or acute events of coronary heart disease. However, the mechanism of GAL8 DNA methylation and gene expression in AS has not been elucidated, prompting us to carry out further research on it.
