Leptin receptor action and mechanisms of leptin resistance [PDF]

open access: yesCellular 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.

Leptin Elicits LTC4 Synthesis by Eosinophils Mediated by Sequential Two-Step Autocrine Activation of CCR3 and PGD2 Receptors

open access: yesFrontiers in Immunology, 2018
Leptin is a cytokine, produced mainly by mature adipocytes, that regulates the central nervous system, mainly to suppress appetite and stimulate energy expenditure.

The role of leptin resistance in the development of thyroid neoplasia

open access: yesMìžnarodnij Endokrinologìčnij Žurnal, 2023
Background. Leptin influences energy metabolism, as it is able to inform the central nervous system about adipose tissue reserves, and is also an important neuroendocrine regulator.

Role of leptin and leptin receptor in inflammation

open access: yesAmerican 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 ...

Relationship Between Circulating Metabolic Hormones and Their Central Receptors During Ovariectomy-Induced Weight Gain in Rats

open access: yesFrontiers in Physiology, 2022
Although increasing research focuses on the phenomenon of body weight gain in women after menopause, the complexity of body weight regulation and the array of models used to investigate it has proven to be challenging.

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

open access: yes, 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 ...

Leptin secretion and leptin receptor in the human stomach [PDF]

open access: yesGut, 2000
BACKGROUND AND AIM 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. Here we investigate

Absence of functional leptin receptor isoforms in the POUND (Lepr(db/lb)) mouse is associated with muscle atrophy and altered myoblast proliferation and differentiation. [PDF]

open access: yesPLoS ONE, 2013
Leptin receptors are abundant in human skeletal muscle, but the role of leptin in muscle growth, development and aging is not well understood. Here we utilized a novel mouse model lacking all functional leptin receptor isoforms (POUND mouse, Lepr(db/lb))

Leptin Suppresses Glutamate-Induced Apoptosis Through Regulation of ERK1/2 Signaling Pathways in Rat Primary Astrocytes

open access: yesCellular Physiology and Biochemistry, 2017
Background/Aims: Leptin is a hormone expressed by adipose tissue that regulates body energy homeostasis and weight loss by activating leptin receptors in the hypothalamus. Leptin receptors are also expressed in astrocytes.
