    Article Snippet: .. THP-1 cells were differentiated into macrophages by incubating with 100 ng/mL phorbol-12-myristate-13-acetate (PMA, HY-18739, MedChemExpress, USA) for 48 h. To induce foam cell formation, the harvested macrophages were cultured in serum-free medium containing 100 ng/mL ox-LDL (HY-NP013, MedChemExpress) for 24 h. .. Cells were treated as indicated, the cell counting kit-8 (CCK-8; HY-K0301, MedChemExpress) reagent was subsequently added in the culture medium and the cells were then incubated for 1 h. The microplate reader (Thermo Fisher Scientific) was used to measure the absorbance at 450 nm.

Continuous variables were expressed as mean ± standard deviation. Comparisons between two groups were performed using Student's t -test, and comparisons among multiple groups were evaluated using one-way ANOVA. Single-cell data analysis was based on R (version 4.4.2) and was mainly completed using R packages such as “Seurat” and “Harmony”. Statistical analysis and visualization were performed in R software and GraphPad Prism 10.1.2. ns: no statistical difference, **: p < 0.01, ***: p < 0.001, ****: p < 0.0001.
