CD14 and atherosclerosis: To screen lncRNA candidates related to atherosclerosis and macrophage polarization, we interrogated human lncRNAs collated from the atherosclerosis progression dataset (GSE120521) and the three datasets on the M1 and M2 macrophage, activated from the human CD14+ monocyte-derived macrophage (GSE55536, GSE146028, GSE140026) in the GEO database (Figure 1A, see Section 4) [19,20,21,22].
