European Journal of Medical Research, 2010 Leptin or obesity receptor (Ob-R) is a member of class I cytokine receptor family. Ob-R, expressed in six isoforms, is the product of alternative RNA splicing of db gene. According to its structural differences, the receptor's isoforms are divided into three classes: long, short, and secretory isoforms.

Leptin and leptin receptor expression in asthma [PDF]
Journal of Allergy and Clinical Immunology, 2009 The adipokine leptin is a potential new mediator for bronchial epithelial homeostasis. Asthma is a chronic inflammatory disease characterized by airway remodeling that might affect disease chronicity and severity. TGF-beta is a tissue growth factor the dysregulation of which is associated with airway remodeling.We sought to determine whether a ...

On the Molecular Evolution of Leptin, Leptin Receptor, and Endospanin [PDF]
Frontiers in Endocrinology, 2017 Over a decade passed between Friedman's discovery of the mammalian leptin gene (1) and its cloning in fish (2) and amphibians (3). Since 2005, the concept of gene synteny conservation (vs. gene sequence homology) was instrumental in identifying leptin genes in dozens of species, and we now have leptin genes from all major classes of vertebrates.

Mutations in the Human Leptin and Leptin Receptor Genes as Models of Serum Leptin Receptor Regulation [PDF]
Diabetes, 2002 A part of serum Ob leptin, an adipocyte-secreted peptide, is bound to a soluble Ob receptor (sObR). Immunoreactive sObR was measured in 125 lean or obese control subjects (group 1), 18 individuals with a mutation in the leptin gene impairing leptin secretion (group 2), and 10 individuals with a mutation in the ObR gene, leading to production of a ...

Leptin and Leptin Receptor Expression in the Rat Ovary [PDF]
Endocrinology, 2003 Leptin is an important satiety hormone and reproductive regulator and is found, along with its receptors, throughout the ovary. To date, the changes in ovarian expression of both of these proteins throughout the estrous cycle has not been studied, and the examination of protein expression has not distinguished between different forms of the receptor ...

Role of leptin and leptin receptor in inflammation
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2003 on october 30th, 2002, the World Health Report by the World Health Organization was launched subtitled Reducing risks, promoting healthy life . Many of the health risks discussed in this report concern food consumption—either too little, in the case of the poor, or too much, in the case of ...

Leptin secretion and leptin receptor in the human stomach [PDF]
Gut, 2000 The circulating peptide leptin produced by fat cells acts on central receptors to control food intake and body weight homeostasis. Contrary to initial reports, leptin expression has also been detected in the human placenta, muscles, and recently, in rat gastric chief cells.

Leptin and Soluble Leptin Receptor in Follicular Fluid [PDF]
Journal of Assisted Reproduction and Genetics, 2003 Previous studies suggest that follicular fluid leptin levels predict successful assisted reproduction. The relationship between intrafollicular leptin and the soluble leptin receptor, ovarian hormones, and oocyte quality was examined to determine potential factors contributing to this finding.Follicular fluid leptin, soluble leptin receptor, hormones ...

Kinetics of Leptin Binding to the Q223R Leptin Receptor
PLoS ONE, 2014 Studies in human populations and mouse models of disease have linked the common leptin receptor Q223R mutation to obesity, multiple forms of cancer, adverse drug reactions, and susceptibility to enteric and respiratory infections. Contradictory results cast doubt on the phenotypic consequences of this variant.

Leptin receptor action and mechanisms of leptin resistance [PDF]
Cellular and Molecular Life Sciences, 2005 The adipose tissue-derived hormone leptin regulates energy balance and neuroendocrine function. Resistance to the appetite-suppressing effects of leptin is associated with common forms of obesity. Here, we review the mechanisms by which leptin activates intracellular signals and the roles that these signals play in leptin action in vivo.
