Limited impact on glucose homeostasis of leptin receptor deletion from insulin- or proglucagon-expressing cells

open access: yesMolecular Metabolism, 2015
Aims/hypothesis: The adipose tissue-derived hormone leptin plays an important role in the maintenance of body weight and glucose homeostasis. Leptin mediates its effects by interaction with leptin receptors (LepRb), which are highly expressed in the ...

Leptin and Notch Signaling Cooperate in Sustaining Glioblastoma Multiforme Progression

open access: yesBiomolecules, 2020
Glioblastoma multiforme (GBM) is the most malignant form of glioma, which represents one of the commonly occurring tumors of the central nervous system.

Leptin in the Commissural Nucleus of the Tractus Solitarius (cNTS) and Anoxic Stimulus in the Carotid Body Chemoreceptors Increases cNTS Leptin Signaling Receptor and Brain Glucose Retention in Rats

open access: yesMedicina, 2022
Background and Objectives: The commissural nucleus of the tractus solitarius (cNTS) not only responds to glucose levels directly, but also receives afferent signals from the liver, and from the carotid chemoreceptors (CChR).

Algebraic study of receptor-ligand systems: a dose-response analysis [PDF]

open access: yesarXiv, 2022
The study of a receptor-ligand system generally relies on the analysis of its dose-response (or concentration-effect) curve, which quantifies the relation between ligand concentration and the biological effect (or cellular response) induced when binding its specific cell surface receptor.

Glucose enhances leptin signaling through modulation of AMPK activity. [PDF]

open access: yesPLoS ONE, 2012
Leptin exerts its action by binding to and activating the long form of leptin receptors (LEPRb). LEPRb activates JAK2 that subsequently phosphorylates and activates STAT3.

Method for identification of condition-associated public antigen receptor sequences [PDF]

open access: yeseLife 2018;7:e33050, 2017
Diverse repertoires of hypervariable immunoglobulin receptors (TCR and BCR) recognize antigens in the adaptive immune system. The development of immunoglobulin receptor repertoire sequencing methods makes it possible to perform repertoire-wide disease association studies of antigen receptor sequences.

Plasma leptin levels in pigs with different leptin and leptin receptor genotypes [PDF]

open access: yesJournal of Animal Breeding and Genetics, 2008
SummaryA C3469T mutation at exon 3 of the pig leptin (Lep) gene has been genotyped in diverse pig breeds yielding controversial results with regard to its association with growth, fatness and carcass traits. A similar situation has been reported for a HpaII restriction fragment length polymorphism (RFLP) in the pig leptin receptor (Lepr) gene, where ...

Leptin into the rostral ventral lateral medulla (RVLM) augments renal sympathetic nerve activity and blood pressure

open access: yesFrontiers in Neuroscience, 2014
Leptin is a hormone released from adipose tissue. While this hormone normally acts to reduce feeding behavior and increase energy expenditure, in obesity, resistance to these effects occurs even though the hormone is released in large amounts. Although

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]

open access: yesProgress in Neurobiology 72(6), pp 399-415, April 2004, 2004
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release. Even though NM receptor regulation is implicated in the pharmacological action of many drugs, and is also known to be influenced by various environmental ...

Leptin receptor signaling: pathways to leptin resistance

open access: yesFrontiers in Bioscience, 2011
The identification of spontaneous mutations in the leptin- and leptin receptor (ObR)-encoding ob and db gene, respectively, opened up a new field in obesity research. Leptin, an adipocyte-derived hormone, mirrors the body's fat stores and thereby informs the brain about the body's energy status.
