Considering roles for GLP-1R+ cells in atherosclerosis, GLP-1R expression has been described within ECs (18) and vascular smooth muscle cells (19, 20), and within immune cell populations (21), with the highest levels of immune cell GLP-1R expression detected within intestinal intraepithelial lymphocytes (IELs) (22). The gene discussed is GLP1R; the disease is atherosclerosis.
