PANoptosis in vascular smooth muscle cells regulated by TNF-α/IL-1β can be a new target for alleviating the progression of abdominal aortic aneurysm.

Clinical samples of patients with AAA, angiotensin II (ANG II)-induced AAA mouse model, and ANG II-induced vascular smooth muscle cells (VSMCs) in vitro model were used for investigation on PANoptosis features.

Endothelial HuR deletion reduces the expression of proatherogenic molecules and attenuates atherosclerosis.

Atherosclerosis is a chronic inflammatory disease of arterial wall, and the proatherogenic molecules derived from endothelium and leukocyte recruitment are major contributors to its pathogenesis.
