The study was aimed at assessing the role of chemokines in inflammatory changes in tissue following abdominoplasty. The levels of neutrophil-coupled chemokines and their receptors in the serum and blood cells, as well as in cells isolated from the subcutaneous adipose tissue sampled during abdominoplasty were compared in patients with obesity and normal body weight. The levels of chemokines CCL3, CCL3, and CCL5 in blood serum and expression of chemokine receptor CXCR2 and CXCR6 on blood neutrophils were significantly higher (p<0.05) in obese patients in comparison with patients with normal body weight. Elevated expression of chemokines CCL2, CCL3, CCL4, CCL5, CCL18, and CCL20 (p<0.05) was detected in subcutaneous adipose tissue cells isolated obese patients in comparisons with persons with normal body weight. These findings attest to favorable conditions for enhanced neutrophil migration to the adipose tissue in patients with obesity, which can promote leukocyte infiltration of the suture site after abdominoplasty and serves as additional risk factor for the development of postoperative complications associated with activity of neutrophil-derived proteolytic enzymes.

Objective: The study objective was to evaluate changes in abdominal adipose tissue and ectopic fat during pregnancy and their associations with gestational weight gain (GWG) in women with overweight/obesity.
Methods: This study was a secondary analysis of a randomized controlled trial. Magnetic resonance scans were performed during gestational week (GW) 15, GW 32, and around birth to measure abdominal subcutaneous (SAT) and visceral (VAT) adipose tissues, liver fat, and muscle fat.

Complete characterization of the genetic effects on gene expression is needed to elucidate tissue biology and the etiology of complex traits. In the present study, we analyzed 2,344 subcutaneous adipose tissue samples and identified 34,774 conditionally distinct expression quantitative trait locus (eQTL) signals at 18,476 genes. Over half of eQTL genes exhibited at least two eQTL signals.

Background: For characterizing health states, fat distribution is more informative than overall body size. We used population-based whole-body magnetic resonance imaging (MRI) to identify distinct body composition subphenotypes and characterize associations with cardiovascular disease (CVD) risk.
Methods: Bone marrow, visceral, subcutaneous, cardiac, renal, hepatic, skeletal muscle and pancreatic adipose tissue were measured by MRI in n = 299 individuals from the population-based KORA cohort.

Localized lipoatrophy is a rare condition characterized by the localized loss of subcutaneous adipose tissue. It may occur idiopathically without specific triggers. The pathogenesis of idiopathic localized lipoatrophy remains largely unknown.

This study aimed to investigate the temporal accumulation of odor fatty acids (OFAs) in the dorsal subcutaneous adipose tissue, and uncover their dynamic regulatory metabolic pathways from the transcriptomic perspective in lambs from birth to market. Thirty-two Hulun Buir lambs were selected and randomly assigned to four different sampling stages following their growth trajectories: neonatal (day 1), weaning (day 75), mid-fattening (day 150), and late-fattening (day 180) stages. Results indicated that the contents of three OFAs increased progressively as lambs matured, with the most drastic change occurred at mid-fattening vs.
