Adipose tissue aging partially accounts for fat alterations in HIV lipodystrophy
ABSTRACT Lipodystrophy is a major disturbance in people living with HIV-1 (PLWH). Several systemic alterations in PLWH are reminiscent of those that occur in ageing. It is unknown whether the lipodystrophy in PLWH is the consequence of accelerated ageing in adipose tissue. We compared systemic and adipose tissue disturbances in PLWH with those in healthy elderly individuals (~80 y old). We observed similarly enhanced expression of inflammation-related genes and decreased autophagy in adipose tissues from elderly individuals and PLWH. Indications of repressed adipogenesis and mitochondrial dysfunction were found specifically in PLWH, whereas reduced telomere length and signs of senesce were specific to elderly individuals. We conclude that ageing of adipose tissue accounts only partially for the alterations in adipose tissues of PLWH.
期刊介绍：
Adipocyte recognizes that the adipose tissue is the largest endocrine organ in the body, and explores the link between dysfunctional adipose tissue and the growing number of chronic diseases including diabetes, hypertension, cardiovascular disease and cancer. Historically, the primary function of the adipose tissue was limited to energy storage and thermoregulation. However, a plethora of research over the past 3 decades has recognized the dynamic role of the adipose tissue and its contribution to a variety of physiological processes including reproduction, angiogenesis, apoptosis, inflammation, blood pressure, coagulation, fibrinolysis, immunity and general metabolic homeostasis. The field of Adipose Tissue research has grown tremendously, and Adipocyte is the first international peer-reviewed journal of its kind providing a multi-disciplinary forum for research focusing exclusively on all aspects of adipose tissue physiology and pathophysiology. Adipocyte accepts high-profile submissions in basic, translational and clinical research.
