We adopted the LCWE‐induced KD murine model to mimic human KD vasculopathy.[3, 23] LCWE‐injected mice exhibited vasculopathy of the abdominal aorta (Figure S3A,C, Supporting Information) and coronary arteries (Figure S3B,D, Supporting Information), which was characterized by immune cell infiltration, elastin degradation, and medial thickening. This evidence concerns the gene ELN and vascular disorder.
