Abstract: Background: Adipose tissue plays a role in the storage of excess energy as triglycerides
(TGs). Excess fat accumulation causes various metabolic and cardiovascular diseases. It has been reported
that ectopic fat deposition and excess TG accumulation in non-adipose tissue might be important
predictors of cardiometabolic and vascular risk. For example, ectopic fat in perivascular tissue
promotes atherosclerotic plaque formation in the arterial wall.
Objective: Recently, it has been reported that ectopic fat (adipocyte) in the vascular wall of an abdominal
aortic aneurysm (AAA) is present in both human and experimental animal models. The
pathological significance of adipocytes in the AAA wall has not been fully understood. In this review,
we summarized the functions of adipocytes and discussed potential new drugs that target vascular adipocytes
for AAA treatment.
Result: Previous studies suggest that adipocytes in vascular wall play an important role in the development
of AAA.
Conclusion: Adipocytes in the vascular wall could be novel targets for the development of AAA
therapeutic drugs.
