AbstractMorphological characteristics and source of adipose tissue as well as adipokines may increase cardiometabolic risk. This study aimed to explore whether adipose tissue characteristics may impact metabolic and atherogenic risks. Subcutaneous Adipose Tissue (SAT), Visceral Adipose Tissue (VAT) and peripheral blood were obtained from obese patients submitted to bariatric surgery. Adipose tissue (morphometry), plasma adiponectin, TNF-α, resistin (multiplexing) and biochemical chemistry were analyzed; as well as endothelial dysfunction (Flow Mediated Dilation, FMD) and atherogenesis (Carotid Intima Media Thickness, CIMT). Subgroups divided by adipocyte size and source were compared; as well as correlation and multivariate analysis. Sixty patients 36.6% males, aged 44 years-old, BMI 46.7 kg/m2 were included. SAT’s adipocytes showed a lower range of size expandability than VAT’s adipocytes. Independent from their source, larger adipocytes were associated with higher glucose, lower adiponectin and higher CIMT. Particularly, larger adipocytes from SAT were associated with higher blood pressure, lower insulin and HDL-cholesterol; and showed positive correlation with glucose, HbA1c, systolic/diastolic values, and negatively correlated with insulin and adiponectin. VAT’s larger adipocytes particularly associated with lower resistin and lower FMD values. Gender and Diabetes Mellitus significantly impacted the relation of adipocyte size/source with the metabolic and atherogenic risk. Multivariable analysis suggested hypertension-resistin-HbA1c interactions associated with SAT’s larger adipocytes; whereas potential insulin-adiponectin associations were observed for VAT’s larger adipocytes. Adipocyte morphology and source are differentially related with cardiometabolic and atherogenic risk in population with obesity, which are potentially affected by gender and Diabetes Mellitus.

Abstract Obesity is defined as increased adiposity, which leads to metabolic disease. The growth of adipose tissue depends on its capacity to expand, through hyperplasia or hypertrophy, in order to buffer energy surplus. Also, during the establishment of obesity, adipose tissue expansion reflects adipose lipid metabolism (lipogenesis and/or lipolysis). It is well known that dietary factors can modify lipid metabolism promoting or preventing the development of metabolic abnormalities that concur with obesity. Trans-palmitoleic acid (TP), a biomarker of dairy consumption, has been associated with reduced adiposity in clinical studies. Thus, we aimed to evaluate the effect of TP over adiposity and lipid metabolism-related genes in a rodent model of diet-induced obesity (DIO). To fulfil this aim, we fed C57BL/6 mice with a Control or a High Fat diet, added with or without TP (3g/kg diet), during 11 weeks. Body weight and food intake were monitored, fat pads were weighted, histology of visceral adipose tissue was analysed, and lipid metabolism-related gene expression was explored by qPCR. Results show that TP consumption prevented weight gain induced by high fat diet, reduced visceral adipose tissue weight, and adipocyte size, while increasing the expression of lipolytic molecules. In conclusion, we show for the first time that TP influences adipose tissue metabolism, specifically lipolysis, resulting in decreased adiposity and reduced adipocyte size in a DIO mice model.

Abstract Context Gestational diabetes mellitus (GDM) is accompanied by subclinical inflammation; however, little is known about local inflammation in adipose tissue and placenta. Objective To analyze systemic and local subclinical inflammation and adipose tissue lymphocyte content and phenotype in pregnant women with and without GDM. Design Observational study. Settings Academic hospital. Patients Twenty-one pregnant women with GDM (GDM group), 16 pregnant women without GDM (non-GDM group) and 15 nonpregnant control women (N group). Interventions Serum samples taken at 28 to 32 (visit 1 [V1]) and 36 to 38 (V2) gestational weeks and 6 to 12 months after delivery (V3) in the GDM and non-GDM group and before elective gynecological surgery in the N group. Subcutaneous (SAT) and visceral adipose tissue (VAT) obtained during cesarean delivery or surgery. Main Outcome Measures Serum levels and adipose tissue expression of proinflammatory cytokines, adipose tissue lymphocyte content and phenotype (for a subset of GDM and non-GDM subjects). Results Accented proinflammatory state in GDM was documented by increased circulating tumor necrosis factor-α (TNF-α) levels. In both groups of pregnant females total lymphocytes were higher in VAT compared to SAT. In GDM subjects B cells and NKT cells were higher in SAT compared to VAT and T helper cells were increased relative to SAT of non-GDM group, while no intercompartmental adipose tissue differences were seen in non-GDM women. Conclusions Pregnant females had higher total lymphocyte count in VAT relative to SAT regardless of GDM. In addition to increased systemic subclinical inflammation, GDM was associated with significant differences in lymphocyte composition between subcutaneous and visceral adipose tissue depots.
