Thrombospondin‐4 is upregulated in abdominal aortic aneurysm: A vasoprotective response with potential therapeutic relevance

British Journal of Pharmacology, Volume 183, Issue 12, Page 3321-3339, June 2026.
TSP4 is upregulated in human and experimental AAA. TSP4 knockdown accelerated AAA formation and exacerbated both vascular inflammation and remodelling, emphasizing that TSP4 upregulation may represent a protective response against AAA. Our findings suggest that preserving TSP4 could be a useful strategy in the clinical management of AAA.
