Roles of leptin and resistin in metabolism, reproduction, and leptin resistance
Domestic Animal Endocrinology, 2020Increased adipose mass can cause insulin resistance and type 2 diabetes mellitus. This phenomenon is related to adipocyte-secreted signaling molecules that affect glucose balance, such as fatty acids, adiponectin, leptin, interleukin-6, tumor necrosis factor-α, and resistin.

Leptin, Obesity, and Leptin Resistance
2014The cloning of leptin in 1994 was an important milestone in obesity research. In those days obesity was rather stigmatized as a condition caused by lack of character and self-control. With leptin and its receptor being the first single genes that could cause morbid obesity in man and mice, it is now appreciated that obesity is caused by a dysregulation

Drug targeting of leptin resistance
Life Sciences, 2015Leptin regulates glucose, lipid and energy homeostasis as well as feeding behavior, serving as a bridge between peripheral metabolically active tissues and the central nervous system (CNS). Indeed, this adipocyte-derived hormone, whose circulating levels mirror fat mass, not only exerts its anti-obesity effects mainly modulating the activity of ...

Leptin-Signaling Pathways and Leptin Resistance
2009Leptin acts as an anorexigenic hormone in the brain, where the long form of the leptin receptor (LRb) is widely expressed in hypothalamic and extra-hypothalamic sites that are known to participate in diverse feeding circuits. The important role of leptin in energy homeostasis is demonstrated by the profound hyperphagia and morbid obesity in humans and ...

Leptin Resistance - Or Why Leptin Fails to Work in Obesity
Experimental and Clinical Endocrinology & Diabetes, 2003In experimental models of obesity high serum concentrations of leptin without subsequent inhibition of food intake indicate a resistance to the physiological effects of leptin. Similar to the animal model leptin concentrations in most of the obese patients are higher compared to normal-weight persons.

[Leptin Signalings and Leptin Resistance].
Sheng li ke xue jin zhan [Progress in physiology], 2016Leptin plays a critical role in the regulation of energy balance and metabolic homeostasis. Impairment of leptin function is closely involved in the pathogenesis of obesity, diabetes mellitus and some other metabolic diseases. Leptin initiates intracellular signal transductions in the leptin-receptor-expressing neurons in the central nervous system to ...

Role of leptin and adiponectin in insulin resistance
Clinica Chimica Acta, 2013Adipose tissue is a major source of energy for the human body. It is also a source of major adipocytokines adiponectin and leptin. Insulin resistance is a condition in which insulin action is impaired in adipose tissue and is more strongly linked to intra-abdominal fat than to fat in other depots.

Leptin resistance and hippocampal behavioral deficits
Physiology & Behavior, 2017The adipocyte-derived hormone leptin is an important regulator of body weight and metabolism through activation of brain leptin receptors expressed in regions such as the hypothalamus. Beyond these well described and characterized activities of leptin in the hypothalamus, it is becoming increasingly clear that the central activities of leptin extend to

Modulation of leptin resistance by food compounds
Molecular Nutrition & Food Research, 2016Leptin is mainly secreted by white adipose tissue and regulates energy homeostasis by inhibiting food intake and stimulating energy expenditure through its action in neuronal circuits in the brain, particularly in the hypothalamus. However, hyperleptinemia coexists with the loss of responsiveness to leptin in common obese conditions.

leptin was cloned in 1994 and shown to be secreted from adipocytes ([5][1]). This and subsequent studies demonstrated that leptin is made and secreted in proportion to the fat content of individual adipocytes ([4][2]).
