Monocyte-associated chemokine expression in cells from subcutaneous adipose tissue isolated from operation material in patients during abdominoplasty

Abstract

Aim: we study the relationship between chemokines and intensity of the inflammatory process in the subcutaneous adipose tissue (SAT) in individuals with obesity and normal body weight. Objective: we determined the expression levels of chemokines associated with monocyte/macrophages, as well as their receptors on the cells of SAT, that were obtained during abdominoplasty. Patients. In this work we have used the biological material of 262 women to whom has been performed an abdominoplasty in the Clinic of plastic and aesthetic surgery from 2013 to 2017 years. Methods. Body composition and the weight of body fat were determined by bioimpedance analysis. SATs have been obtained during abdominoplasty surgery. SAT cells were isolated followed by the staining with fluoresceine labeled antibodies which fluorescence was analyzed using a flow cytometer FACSCalibur according to the program SimulSet. Statistical analysis was carried out using ANOVA. Results. It has been shown that the progressing obesity may affect the SAT cellular composition. The expression of chemokines from CC family and its receptors (CCR1, CCR2 and CCR5) on cells from SAT were significantly higher in patients with obesity compared to the normal body weight patients. Conclusions. Differences in the chemokine expression on SAT cells between patients with obesity and with normal body weight may reflect the functional features of SAT itself and can modify the complication developments after abdominoplasty.
