GLUT expression mononuclear cells

The progressive lung destruction in cystic fibrosis (CF) is tightly associated with chronic bacterial infection and neutrophil-dominated airway inflammation. CF pulmonary disease is complicated by episodes of acute exacerbations, contributing to irreversible lung damage. We hypothesized that circulating subsets of neutrophils from clinically stable adults with CF present some phenotypic specificities that could amplify their activation during an infectious episode. The aim of the present study was to examine the different neutrophil subsets in whole blood and in the low density neutrophils (LDN) that co-purify with peripheral blood mononuclear cells (PBMC) in clinically stable adults with CF and in CF adults during pulmonary exacerbations compared to healthy donors...

Recent evidence suggests that comorbidities between neuropsychiatric conditions and metabolic syndrome may precede and even exacerbate long-term side-effects of psychiatric medication, such as a higher risk of type 2 diabetes and cardiovascular disease, which result in increased mortality. In the present study we compare the expression of key metabolic proteins, including the insulin receptor (CD220), glucose transporter 1 (GLUT-1) and fatty acid translocase (CD36), on peripheral blood mononuclear cell subtypes from patients across the neuropsychiatric spectrum, including schizophrenia, bipolar disorder, major depression and autism spectrum conditions (n=25/condition), relative to typical controls (n=100)...

BACKGROUND: Few cases or peri-implant peripheral giant cell lesions (PGCL) have been reported in the literature. The aim of this study was to report 13 new cases of peri-implant PGCL and compare the expression of smooth muscle actin, Bcl-2 protein, GLUT-1, CD68, osteoprotegerin, receptor activator of nuclear factor kappa-B, Ki-67 and CD34 in these cases with PGCL and central giant cell lesions (CGCL). MATERIAL AND METHODS: Clinical data were retrieved from the laboratory records and histological analysis was performed using HE-stained slides...

BACKGROUND: We assessed the effects of vitamin D supplementation on the associated molecular mechanisms that are involved in insulin and lipid metabolism of diabetic hemodialysis (HD). METHODS: A double-blind, randomized, placebo-controlled clinical trial was carried out in 55 patients with diabetic HD. In the current project, we were used two groups which each subject received vitamin D supplements (50,000 IU, n=28) or placebo (50,000 IU, n=27) every 2 weeks for 12 weeks...

Purpose: This study was performed to determine the effects of chromium supplementation on the gene expression of insulin, lipid, and inflammatory markers in infertile women with polycystic ovary syndrome (PCOS) who were candidate for in vitro fertilization (IVF). Methods: Forty women, aged 18-40 years, who had been selected for IVF were recruited in this randomized double-blinded, placebo-controlled trial. They ( n = 20/group) were randomly assigned into intervention groups to take either 200 μg/day of chromium or placebo for 8 weeks...

BACKGROUND: There exists a general recognition of the fact that mitochondrial remodelling as a result of aerobic glycolysis ensures human somatic cells to revert to a more primitive-form exhibiting stem-like phenotype. The present study is an attempt to demonstrate that miR-2909 RNomics within human peripheral blood mononuclear cells (PBMCs) has the inherent capacity to re-program these cells to exhibit mitochondrial remodelling paralleled by aerobic glycolysis together with intracellular lipid inclusions...

BACKGROUND: This study was conducted to determine the effects of fish oil administration on gene expression related to insulin, lipid and inflammation in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: This randomized, double-blind, placebo-controlled trial was conducted among 40 subjects with PCOS, aged 18-40 years. Subjects were randomly allocated into two groups to take either 1000 mg omega-3 fatty acids from fish oil (n = 20) or placebo (n = 20) twice a day for 12 weeks...

OBJECTIVE: The aim of this study was to evaluate the effects of omega-3 and vitamin E co-supplementation on parameters of mental health and gene expression related to insulin and inflammation in subjects with polycystic ovary syndrome (PCOS). METHODS: Forty PCOS women were allocated into two groups and treated with 1000mg omega-3 fatty acids plus 400 IU vitamin E supplements (n = 20) or placebo (n = 20) per day for 12 weeks. Parameters of mental health were recorded at baseline and after the 12-week intervention...

The study of the health status in long-living individuals (LLIs) may help identifying health-span and life-span determinants. BPI-Fold-Containing-Family-B-Member-4 (BPIFB4) protein is higher in healthy vs. non-healthy (frail) LLIs serum and its longevity-associated variant forced expression improves cardiovascular outcomes in ischemia mice models. Thus, we tested the association of BPIFB4 and ischemia-responding HIF-1α pathway components (i.e. CXCR4 , AK3, ALDO-C, ADM , VEGF-A , GLUT-1 and miR-210) with human life-span and health-span by analyzing mRNA expression in circulating mononuclear cells (MNCs) of LLIs (N=14 healthy; N=31 frail) and young controls (N=63)...

The use of antipsychotics carries the risk of metabolic side effects, such as weight gain and new onset type-2 diabetes mellitus. The mechanisms of the observed metabolic alterations are not fully understood. We compared the effects of two atypical antipsychotics, one known to favor weight gain (olanzapine), the other not (aripiprazole), on glucose metabolism. Primary human peripheral blood mononuclear cells (PBMC) were isolated and stimulated with olanzapine or aripiprazole for 72 h. Cellular glucose uptake was analyzed in vitro by 18F-FDG uptake...

SCOPE: We have investigated the potential use of β-conglutin protein isoforms from narrow-leafed lupin (Lupinus angustifolius L.) as a diabetes treatment. METHODS AND RESULTS: We produced purified recombinant β1-, β2-, β3-, β4-, and β6-conglutin proteins and showed that β1, β3, and β6 could bind to insulin. To assess β-conglutin proteins modulatory effect on insulin activation meditated kinases, whole blood and peripheral blood mononuclear cell cultures from type 2 diabetes (T2D) and healthy control subjects (C) were incubated with conglutin proteins...

It was previously demonstrated that metabolic syndrome in humans is associated with an impairment of insulin signalling in circulating mononuclear cells. At least in animal models of hypertension, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARB) may correct alterations of insulin signalling in the skeletal muscle. In the first study, we investigated the effects of a 3-month treatment with an ARB with additional PPARγ agonist activity, telmisartan, or with a dihydropyridine calcium channel blocker, nifedipine, on insulin signalling in patients with mild-moderate essential hypertension...

The transition period of dairy cows is characterized by dramatic changes in metabolism and immune cell function that contributes to increased susceptibility to several economically important diseases. Monocyte and macrophage populations increase in blood and tissues of cows during the transition period and have enhanced inflammatory responses that may contribute to increased severity of disease. Glucose is a major energy source for activated monocytes and glucose uptake is facilitated by glucose transporters (GLUT)...

Umbilical cord blood (UCB)-derived mesenchymal stem cells (MSCs) are multipotent cells. They are able to differentiate into functional cells from not only mesoderm but also endoderm. Many researches showed that cells derived from fresh human UCB could transdifferentiate into insulin-secreting cells. In this study, transdifferentiating potential of cryopreserved human UCB-derived MSCs into insulin-secreting cell was investigated. Fresh human UCB was enriched the mononuclear cells by Ficoll-Paque centrifugation...

Hypoxia is an important regulator of bone biology and stimulates osteoclast differentiation from monocytic precursors. Hypoxia-inducible factor (HIF) is a key pro-tumourigenic transcription factor mediating pathways of hypoxia-inducible gene expression. We have described expression of HIF-1alpha and HIF-2alpha in the multi-nucleated, osteoclast-like giant cells and the mononuclear stromal component of giant cell tumour of bone (GCTB), a locally osteolytic primary bone tumour. HIF induction was observed in culture in the osteoblastic MG-63 cell line, primary GCTB stromal cells, and monocyte-derived osteoclasts following stimulation with hypoxia (0...

Globoid cell leukodystrophy, or Krabbe's disease, is a severe disorder of the central and peripheral nervous system caused by the absence of galactocerebrosidase (GALC) activity. Herein, we describe the clinical, neuropathological, histochemical, and immunohistological features observed in rhesus macaques affected with Krabbe's disease. Clinical signs included pronounced muscle tremors of head and limbs, difficulty ambulating, ataxia, hypermetria, proprioceptive deficits, and respiratory abnormalities. Histopathologically, all animals presented with evidence of demyelination in the peripheral and central nervous systems and accumulation of mononuclear and multinuclear globoid cells in the cerebral and cerebellar white matter associated with severe gliosis...

AIMS/HYPOTHESIS: Viral infections and local production of IFN-gamma might contribute to beta-cell dysfunction/death in Type 1 Diabetes. Double stranded RNA (dsRNA) accumulates in the cytosol of viral-infected cells, and exposure of purified rat beta cells to dsRNA (tested in the form of polyinosinic-polycytidylic acid, PIC) in combination with IFN-gamma results in beta-cell dysfunction and apoptosis. To elucidate the molecular mechanisms involved in PIC + IFN-gamma-effects, we determined the global profile of genes modified by these agents in primary rat beta cells...
