Abstract
Aging is widely regarded as an irreversible arrest of cellular growth and proliferation, often accompanied by systemic metabolic organ abnormalities, ultimately reducing quality of life and increasing mortality in the elderly. Multi-organ transcriptomic analyses suggest that adipose tissue is among the earliest organs to respond to aging, characterized by changes in fat content and redistribution of adipose tissue, decline in thermogenic adipose function, reduced proliferation and differentiation capacity of adipose progenitor and stem cells, accumulation of senescent cells, and immunosenescence. These alterations may act synergistically and play a role in abnormalities in metabolic organs including the cardiovascular, liver, skeletal muscle, and brain. Studies have demonstrated that exercise ameliorates the effects of adipose tissue aging on metabolic organ abnormalities by inhibiting inflammation, reducing the accumulation of ectopic lipids, enhancing the browning of white adipose tissue and thermogenesis in brown adipose tissue, improving lipid metabolism, regulating the secretion of adipokines, and mitigating immunosenescence. This review summarizes the main characteristics of adipose tissue aging, the effects of adipose tissue aging on metabolic organ abnormalities, and the potential mechanisms by which exercise ameliorates the effects of adipose tissue aging on metabolic organ abnormalities. It provides theoretical support for basic and clinical research on exercise-based prevention and treatment of aging-related diseases.
期刊介绍：
Lipids in Health and Disease is an open access, peer-reviewed, journal that publishes articles on all aspects of lipids: their biochemistry, pharmacology, toxicology, role in health and disease, and the synthesis of new lipid compounds.
Lipids in Health and Disease is aimed at all scientists, health professionals and physicians interested in the area of lipids. Lipids are defined here in their broadest sense, to include: cholesterol, essential fatty acids, saturated fatty acids, phospholipids, inositol lipids, second messenger lipids, enzymes and synthetic machinery that is involved in the metabolism of various lipids in the cells and tissues, and also various aspects of lipid transport, etc. In addition, the journal also publishes research that investigates and defines the role of lipids in various physiological processes, pathology and disease. In particular, the journal aims to bridge the gap between the bench and the clinic by publishing articles that are particularly relevant to human diseases and the role of lipids in the management of various diseases.
