Rauch et al. show that loss-of-function mutations in the epigenetic regulator Dnmt3a lead to accelerated atherosclerosis, as previously shown for Tet2, and that loss of either gene leads to similar changes in atheroma composition, with the emergence of a distinct population of chemokine-enriched, resident-like macrophages infiltrating the adventitia, as revealed by single-cell transcriptomics and spatial proteomic analyses.
