The adipocyte-derived hormone leptin is crucial for energy homeostasis in mammals; mice and humans without it suffer from a voracious appetite and extreme obesity. The effect on energy balance of variations in plasma leptin above a minimal threshold is uncertain, however, particularly in humans. Here we examine a group of individuals who are genetically partially deficient in leptin, and show that differences in circulating leptin levels within the range found in normal human populations can…

The purpose of the present review is to summarize the important aspects of the biology, actions, and regulation of leptin and to serve as an update of new information.
The role of leptin in regulating bone metabolism.
The literature the indirect and direct pathways through which leptin acts to influence bone metabolism and the clinical utility of leptin in leptin deficient individuals and its potential to improve metabolic bone disease are reviewed.
Narrative Review: The Role of Leptin in Human Physiology: Emerging Clinical Applications
Replacement of leptin in physiologic doses restores ovulatory menstruation in women with hypothalamic amenorrhea and improves metabolic dysfunction in patients with lipoatrophy, including lipoat rophy associated with HIV or highly active antiretroviral therapy.

The potential clinical usefulness of leptin in several disease states in children and adolescents, including hypothalamic amenorrhea, eating disorders and syndromes of insulin resistance is still under investigation.
Leptin treatment: facts and expectations.
For patients with lipodystrophy, hypothalamic amenorrhea, and congenital leptin deficiency, leptin replacement therapy with metreleptin (a recombinant leptin analog) has improved or normalized most of their phenotypes, including normalization of endocrine axes, decrease in insulin resistance, and improvement of lipid profile and hepatic steatosis.
Control of energy homeostasis and insulin action by adipocyte hormones: leptin, acylation stimulating protein, and adiponectin

These adipocyte hormones, the pathways controlling their production, and their receptors represent promising targets for managing obesity, hyperlipidemia, and insulin resistance.
Leptin and the Onset of Puberty
It is shown that administration of recombinant human leptin results in the onset of puberty at an appropriate developmental age in human congenital leptin deficiency, suggesting that leptin is a metabolic gate for the onsetof puberty in humans.
Update on adipocyte hormones: regulation of energy balance and carbohydrate/lipid metabolism.
The biology, actions, and regulation of three adipocyte hormones-leptin, acylation stimulating protein (ASP), and adiponectin-with an emphasis on the most recent literature are addressed.
Genetics of obesity in humans.
How far the characterization of patients has informed understanding of the physiological role of leptin and the melanocortins in the regulation of human body weight and neuroendocrine function is discussed.
The long road to leptin.

  • 2016
The identification of leptin has provided a framework for studying the pathogenesis of obesity in the general population, clarified the nature of the biologic response to starvation, and helped to advance the understanding of the neural mechanisms that control feeding.


Effects of recombinant leptin therapy in a child with congenital leptin deficiency.
The administration of leptin corrects their obesity by reducing their food intake and increasing their energy expenditure and these mice also have hyperinsulinemia, corticosterone excess, and infertility, which also are reversed by treatment with leptin.
Role of adipose tissue in body-weight regulation: mechanisms regulating leptin production and energy balance

Adipose tissue performs complex metabolic and endocrine functions. Among the endocrine products produced by adipose tissue are tumour necrosis factor α, interleukin 6, acylation-stimulating protein
Congenital leptin deficiency is associated with severe early-onset obesity in humans
The severe obesity found in two severely obese children who are members of the same highly consanguineous pedigree provides the first genetic evidence that leptin is an important regulator of energy balance in humans.
Positional cloning of the mouse obese gene and its human homologue
The ob gene product may function as part of a signalling pathway from adipose tissue that acts to regulate the size of the body fat depot.
Relatively low plasma leptin concentrations precede weight gain in Pima Indians
Leptin, the product of the ob gene1, is a hormone, produced by adipose cells, that inhibits food intake2–5 and increases energy expenditure2,3 in rodents. In humans, plasma leptin concentrations
Recombinant leptin for weight loss in obese and lean adults: a randomized, controlled, dose-escalation trial.
Administration of exogenous leptin appears to induce weight loss in some obese subjects with elevated endogenous serum leptin concentrations and a dose-response relationship with weight and fat loss was observed with subcutaneous recombinant leptin injections in both lean and obese subjects.

This perspective, although respectful of the profound impact that leptin’s discovery has had upon understanding of obesity and on the field of obesity research, will attempt to deemphasize the physiological status of leptin as an anti-obesity hormone, stressing instead its roles as a signal of energy deficiency and as an integrator of neuroendocrine function.
Body mass index as a measure of body fatness: age- and sex-specific prediction formulas.
Internal and external cross-validation of the prediction formulas showed that they gave valid estimates of body fat in males and females at all ages, however, in obese subjects however, the prediction formula slightly overestimated the BF%.
Metabolic fluctuation during a muscle contraction cycle.
Gated31P-nuclear magnetic resonance followed the metabolic fluctuation in rat gastrocnemius muscle during a contraction cycle and revealed that a substantial energy fluctuation accompanies a muscle twitch.
