Hans CP et al. [23] reported that DAPT reverted proinflammatory genes back to baseline in macrophages and increased anti-inflammatory genes, including c-Myc, Egr2, and Arg1, in LPS-stimulated macrophages, preventing the progression of active abdominal aortic aneurysm (AAA). Here, ARG1 is linked to abdominal aortic aneurysm.
