Mediators of Inflammation, 2019 Leptin resistance is either a condition induced by human obesity or a natural phenomenon associated with seasonality in ruminants. In the cardiovascular system, the leptin resistance state presence is a complex issue.

The glucoregulatory actions of leptin
Molecular Metabolism, 2017 Background: The hormone leptin is an important regulator of metabolic homeostasis, able to inhibit food intake and increase energy expenditure. Leptin can also independently lower blood glucose levels, particularly in hyperglycemic models of leptin or ...

Expression of leptin and leptin receptor isoforms in the human stomach [PDF]
Gut, 2000 Leptin is an important regulator of food intake and energy expenditure. Initially it was thought to be expressed exclusively in and secreted by adipocytes. Recently, leptin expression was also noted in other tissues, including rat gastric mucosa.

A Thermodynamic Model for Receptor Clustering [PDF]
, 1999 Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex [PDF]
Physiological Reports, 30th Dec. 2016, Vol. 4 no. e13051, 2016 NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability. There are different NMDA receptor subtypes which differ in their single-channel conductance.

Leptin and leptin receptors during malaria infection in mice [PDF]
Folia Parasitologica, 2002 Leptin, which is involved in a range of physiological processes, could be an important factor in the pathogenesis of malaria. We found that levels of leptin in serum and urine in Plasmodium berghei-infected mice increased progressively after infection, reaching a maximum value on day 6 post-infection. Serum values were approximately five-fold higher in

Leptin in the Respiratory Tract: Is There a Role in SARS-CoV-2 Infection?
Frontiers in Physiology, 2021 Leptin is a pleiotropic adipocytokine involved in several physiologic functions, with a known role in innate and adaptive immunity as well as in tissue homeostasis.

Cargo binding promotes KDEL receptor clustering at the mammalian cell surface [PDF]
Sci. Rep. 6, 28940, 2016, 2017 Transmembrane receptor clustering is a ubiquitous phenomenon in pro- and eukaryotic cells to physically sense receptor/ligand interactions and subsequently translate an exogenous signal into a cellular response. Despite that receptor cluster formation has been described for a wide variety of receptors, ranging from chemotactic receptors in bacteria to ...

Leptin and leptin-receptor polymorphisms in fertile and infertile men [PDF]
Systems Biology in Reproductive Medicine, 2016 The association of leptin (LEP) -2548G/A and/or leptin receptor (LEPR) Gln223Arg polymorphisms with male infertility and plasma FSH, LH, and testosterone (T) levels was examined. The genotypes and allele frequency distributions of LEP -2548G/A and LEPR Gln223Arg polymorphisms were investigated in 150 fertile and 150 infertile men by polymerase chain ...

Leptin and its cardiovascular effects: Focus on angiogenesis
Advanced Biomedical Research, 2015 Leptin is an endocrine hormone synthesized by adipocytes. It plays a key role in the energy homeostasis in central and peripheral tissues and has additional roles are attributed to it, such as the regulation of reproduction, immune function, bone ...
