Adipokines are substances secreted by white adipose tissue of auto-, para- and endocrine functions. They play part mainly in maintaining energy balance. Aging influences the profile of secreted adipokines, what is caused probably by increasing visceral fat, intensified low grade systemic inflammation (LGSI) and the change in adipocyte size. In this article we focus on some selected adipokines (leptin, adiponectin, visfatin, vaspin, omentin, chemerin and retinol binding protein 4 – RBP4) paying special attention to the impact of aging on their blood concentrations and functions. Blood concentrations of leptin, vaspin, chemerin and RBP4 increase with age. It is associated with adverse lipid profile, insulin resistance and the increased risk of cardiovascular diseases, type 2 diabetes, malignancies and autoimmunity. It has been proved that long-lived people have more beneficial adipokines profile i.e. low leptin and especially high adiponectin concentrations what is additionally connected with higher concentration of HDL cholesterol, lower concentrations of HbA1C hemoglobin and C-reactive protein, lower waist-to-hip ratio and fat mass. Moreoer, it seems that maintaining high adiponectin and omentin blood concentrations with low fat mass and preserved insulin sensitivity promote longevity. Furthermore, it has been proved that intensive exercises in old age lead to beneficial changes in adipokines profile, decrease in visceral fat, better insulin sensitivity and lipid profile.

Key words: adipokines, adipose tissue, aging
