Key result
Perivascular adipose tissue dysfunction worsens obesity-related hypertension and organ damage via inflammation and dysregulated adipokines.
Why the study?
Obesity increases susceptibility to hypertension, and the role of perivascular adipose tissue in modulating vascular function and contributing to obesity-related hypertension requires clarification.
This review highlights the mechanistic role of perivascular adipose tissue dysfunction, inflammation, and immune cell infiltration in the pathogenesis of obesity-related hypertension.

“The mechanistic links between obesity and cardiometabolic diseases is poorly understood because the solution is obvious, right? 'Just go on a diet'. But we all know that weight loss is incredibly difficult, and keeping the weight off is a continuous battle. So, there is a desperate need to fully understand how obesity causes these diseases, so that we can develop better treatments.”
Highlights perivascular adipose tissue as potential therapeutic target in obesity-related hypertension; hypothesis-generating and requires prospective validation before practice change.
Background: Obesity and hypertension (HTN) are two of the most prevalent and pressing current global health issues due to their associated morbidity and mortality. Obese individuals are more susceptible to developing HTN. Perivascular adipose tissue (PVAT) has been posited to be the fourth layer of the normal arterial wall. PVAT can modulate vascular tone, vascular endothelial function, and vascular smooth muscle cell growth and proliferation, contributing to HTN. Results: In obesity-related HTN, PVAT exhibits abnormal vasoactive adipokine production and immune cell recruitment as well as enhanced inflammation, which exacerbate blood pressure elevation and lead to target organ damage. Distinct immune cell populations have been identified to infiltrate PVAT, which can become potential therapeutic targets. Conclusion: This paper reviews PVAT dysfunction in obesity-related HTN, highlighting the vasoactive factor release, immune cell infiltration, and inflammation, as well as implications for therapeutic approaches.

Nguyen et al. (2026) conducted a review in Obesity-related hypertension. Perivascular adipose tissue (PVAT) dysfunction was evaluated. Perivascular adipose tissue dysfunction in obesity-related hypertension exacerbates blood pressure elevation and target organ damage via abnormal adipokine production and immune cell infiltration.
