Anti-leptin receptor antibody mimics the stimulation of lipolysis induced by leptin in isolated mouse fat pads

Journal of Lipid Research, 2001
An anti-leptin receptor polyclonal antibody (receptor antibody), as well as leptin, stimulated the release of free fatty acids from isolated mouse fat pads in a time-dependent manner.

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.

Obesity and the ageing brain : could leptin play a role in neurodegeneration? [PDF]

, 2011
Obesity and ageing are both characteristics of the human population that are on the increase across the globe. It has long been established that ageing is the major risk factor for neurodegenerative conditions such as Alzheimer’s disease, and it is ...

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.

The role of insulin receptor substrate 2 in hypothalamic and β cell function [PDF]

, 2005
Insulin receptor substrate 2 (Irs2) plays complex roles in energy homeostasis. We generated mice lacking Irs2 in β cells and a population of hypothalamic neurons (RIPCreIrs2KO), in all neurons (NesCreIrs2KO), and in proopiomelanocortin neurons ...

Evaluation of the leptin receptor in human spermatozoa

Reproductive Biology and Endocrinology, 2010
Background Leptin, a 167 amino acid peptide hormone, profoundly effects reproduction exerting its biological effects via interaction with the leptin receptor (ObR) which is widely expressed on peripheral tissues.

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 ...

Identification of a non-mammalian leptin-like gene:characterization and expression in the tiger salamander (Ambystoma tigrinum) [PDF]

, 2006
Leptin is well established as a multifunctional cytokine in mammals. However, little is known about the evolution of the leptin gene in other vertebrates. A recently published set of ESTs from the tiger salamander (Ambystoma tigrinum) contains a sequence
