Fibronectin-binding nanoparticles for intracellular targeting addressed by B. burgdorferi BBK32 protein fragments.

2011

Virus-like particles (VLPs) are created by the self-assembly of multiple copies of envelope and/or capsid proteins from many viruses, mimicking the conformation of a native virus. Such noninfectious nanostructures are mainly used as antigen-presenting platforms, especially in vaccine research; however, some of them recently were used as scaffolds in biotechnology to produce targeted nanoparticles for intracellular delivery. This study demonstrates the creation of fusion VLPs using hepatitis B core protein-based system maintaining a fibronectin-binding property from B. burgdorferi BBK32 protein, including the evidence of particles’ transmission to BHK-21 target cells via caveolae/rafts endoc…

Effects of fatiguing jumping exercise on mRNA expression of titin-complex proteins and calpains.

2009

Eccentric exercise induced by electrostimulation increases mRNA expression of titin-complex proteins in rodent skeletal muscle. In this study, mRNA expression of titin, muscle LIM protein (MLP), cardiac ankyrin repeat protein (CARP), ankyrin repeat domain protein 2 (Ankrd2), diabetes-related ankyrin repeat protein (DARP), and calcium-activated proteinases, calpains, were investigated in human skeletal muscle after fatiguing jumping exercise. Fatiguing jumping exercise did not change mRNA expression of titin, DARP, calpain 1, or calpain 3. MLP, Ankrd2 and calpain 2 mRNA levels were increased 2 days postexercise. CARP mRNA level was already elevated 30 min and remained elevated 2 days postexe…

Adiponectin and Orexin-A as a Potential Immunity Link Between Adipose Tissue and Central Nervous System

2018

Adipose tissue (AT) is strongly associated with development and progression of immune disorders through adipokines secretion, such as adiponectin. This protein has beneficial energetic properties and is involved in inflammation and immunity processes. Three oligomers of circulating Adiponectin with different molecular weight are described: High (HMW), Medium (MMW) and Low (LMW). The HMW is the most biologically active oligomers. On binding to its receptors AdipoR1, AdipoR2, and T-cadherin, adiponectin acts on both innate and acquired immunity. The suppression of NF-kB activation and pro-inflammatory cytokine expression in macrophages is mediated by AdipoR1. AdipoR2 mediates polarization of …

Obesità viscerale, rischio cardiometabolico e ipertrofia ventricolare sinistra: ruolo dell'adiponectina plasmatica

Lo studio è stato disegnato allo scopo di valutare la prevalenza delle comorbilità cardio-metaboliche e le modificazioni morfologiche della struttura del ventricolo sinistro in una coorte di pazienti suddivisi sulla scorta dei valori normali o ridotti di adiponectina.L'obiettivo principale dello studio è stato quello di analizzare se la riduzione dell'adiponectina plasmatica possa essere considerata un marker di rischio cardiometabolico.

Modulation of adipokines and cytokines in gestational diabetes and macrosomia.

2006

Abstract Context/Objective: Not much is known about the implication of adipokines and different cytokines in gestational diabetes mellitus (GDM) and macrosomia. The purpose of this study was to assess the profile of these hormones and cytokines in macrosomic babies, born to gestational diabetic women. Design/Subjects: A total of 59 women (age, 19–42 yr) suffering from GDM with their macrosomic babies (4.35 ± 0.06 kg) and 60 healthy age-matched pregnant women and their newborns (3.22 ± 0.08 kg) were selected. Methods: Serum adipokines (adiponectin and leptin) were quantified using an obesity-related multiple ELISA microarray kit. The concentrations of serum cytokines were determined by ELISA…

Predictors of insulin resistance in patients with obesity: a pilot study.

2012

We compared adipokines and inflammatory markers in obese insulin-sensitive (group A, n = 16) and insulin-resistant (group B, n = 48) patients divided according to homeostasis model assessment of insulin resistance (HOMA-IR). Serum levels of adiponectin, leptin, resistin, high-sensitivity C-reactive protein, interleukin 6, and tumor necrosis factor α were measured. Weight, height, waist (WC) and hip circumferences, waist to hip ratio , weight to height ratio, visceral adiposity index (VAI), and body adiposity index (BAI) were measured. The WC and VAI were significantly higher in group B (113.9 ± 11.1 vs 105.3 ± 9.8cm; P < .01 and 2.3 ± 1.1 vs 1.6 ± 0.9; P < .05, respectively), while s…

Serum osteocalcin is not associated with glucose but is inversely associated with leptin across generations of nondiabetic women.

2012

The skeleton is recognized as an important player in energy metabolism through its interactions with other tissues. Whether the association of osteocalcin with glucose metabolism is age dependent has not been fully addressed.The objective of the study was to examine the age-specific association between different forms of osteocalcin and glucose and adipokines.This was a family-based study across three generations.The study was conducted at a university laboratory.Sixty-four daughter-premenopausal mother-maternal grandmother trios participated in the study.Fasting plasma glucose and insulin concentrations, serum total (tOC), carboxylated (cOC), and uncarboxylated (ucOC = tOC - cOC) osteocalc…

Insulin sensitivity and secretion and adipokine profile in patients with Cushing’s disease treated with pasireotide

2018

Purpose: To evaluate the effect of pasireotide on β-cell and adipose function in patients with Cushing’s disease (CD). Methods: Clinical and hormonal parameters, insulin secretion evaluated by HOMA-β and by the area under the curve (AUC2h) of C-peptide during a mixed meal tolerance test and insulin sensitivity, evaluated by the euglycaemic hyperinsulinaemic clamp, were evaluated in 12 patients with active CD, before and after 6 and 12 months of pasireotide. In addition, a panel of adipokines including leptin (Ob), leptin/leptin receptor ratio (Ob/Ob-R ratio), adiponectin, resistin, visfatin, adipocyte fatty acid binding protein (AFABP) and non-esterified fatty acids (NEFAs) was evaluated at…
