Objective(s): Type 1 diabetes (T1D) is an autoimmune disease resulting from inflammatory destruction of islets β-cells. Nowadays, progress in cell therapy, especially mesenchymal stem cells (MSCs) proposes numerous potential remedies for T1D. We aimed to investigate the combination therapeutic effect of these cells with insulin and metformin on neuropeptide Y, melanoco...

Free and receptor-bound leptin may be regulated by different mechanisms. Genes that influence the concentration of these fractions may have an important functional bearing. We determined circulating leptin receptor concentrations, bound as well as free leptin concentrations, and body composition in 24 monozygotic (MZ) and in 22 dizygotic (DZ) twin pairs. Bound leptin and leptin receptor concent...

Craniopharyngioma (CP) is a benign tumor with high rate of obesity and frequent recurrence. Moreover, the role leptin/leptin receptors axis in prognosis CP still unknown. Plasma leptin concentration mRNA expression were assessed patients CP. association between axis, weight-related outcomes, progression-free survival (PFS) explored patients. Leptin overexpressed tissue compared to normal brain ...

OBJECTIVE The aim was to study the role of leptin in the development of dementia. METHODS Follow-up of the ALEXANDROS cohorts, with baseline measurements in 2000. From 1,136 available subjects free of dementia at baseline, 667 subjects had frozen baseline blood samples for measuring leptin and soluble leptin receptor (sOB-R). The free leptin index (FLI) was calculated as the ratio of leptin t...

To determine if there is a gender dimorphism in the expression of leptin receptors (OB-R170, OB-R128 and OB-R98) and the protein suppressor of cytokine signaling 3 (SOCS3) in human skeletal muscle, the protein expression of OB-R, perilipin A, SOCS3 and alpha-tubulin was assessed by Western blot in muscle biopsies obtained from the m. vastus lateralis in thirty-four men (age = 27.1+/-6.8 yr) and...

OBJECTIVE We prospectively examined plasma levels of leptin and soluble leptin receptor (sOB-R), as well as their interactions with other diabetes risk factors, in relation to type 2 diabetes to elucidate the complex relation between these two biomarkers and diabetes risk. RESEARCH DESIGN AND METHODS Of 32,826 Nurses' Health Study participants who provided blood samples during 1989-1990, 1,05...

Leptin, an adipocyte-derived signaling factor, is a member of the IL-6 cytokine family. However there is no direct evidence of leptin stimulation of the acute phase protein (APP) synthesis which is typical for all other IL-6-like factors. The purpose of this study was to characterize the dynamics of circulating leptin in relation to ten APPs. We used postoperative septic patients as a model of ...
