Hippocampal Leptin Resistance and Cognitive Decline: Mechanisms, Therapeutic Strategies and Clinical Implications. [PDF]
Background: Leptin, an adipokine essential for regulating energy balance, exerts important effects on brain function, notably within the hippocampus, a region integral to learning and memory.

New pharmacological perspectives for the leptin receptor in the treatment of obesity [PDF]
After its discovery in 1994, leptin became the great hope as an anti-obesity treatment based on its ability to reduce food intake and increase energy expenditure.

Removing melatonin receptor type 1 signaling leads to selective leptin resistance in the arcuate nucleus. [PDF]
Recent studies have highlighted the involvement of melatonin in the regulation of energy homeostasis. In this study, we report that mice lacking melatonin receptor 1 (MT1KO) gained more weight, had a higher cumulative food intake, and were more ...

Hyperleptinemia is required for the development of leptin resistance. [PDF]
Leptin regulates body weight by signaling to the brain the availability of energy stored as fat. This negative feedback loop becomes disrupted in most obese individuals, resulting in a state known as leptin resistance.

The Phlorotannin-Rich Fraction of Ecklonia cava Extract Attenuated the Expressions of the Markers Related with Inflammation and Leptin Resistance in Adipose Tissue. [PDF]
Obesity is associated with systemic chronic inflammation, and it induces central leptin resistance which blocks the appetite-suppressing effect of leptin and leptin resistance in adipocytes. In the present study, we evaluated the effects of Ecklonia cava

Sildenafil ameliorates leptin resistance and normalizes lipid handling in the hypothalamic and adipose tissues of testosterone-exposed pregnant rats. [PDF]
Leptin and hypothalamic-adipose lipid handling are relevant in determining the shift of metabolic activities. There are scanty findings connecting glucose dysregulation as a result of hyperandrogenism during gestation to hypothalamic-adipose axis and ...

Melatonin Absence Leads to Long-Term Leptin Resistance and Overweight in Rats. [PDF]
Melatonin (Mel), a molecule that conveys photoperiodic information to the organisms, is also involved in the regulation of energy homeostasis. Mechanisms of action of Mel in the energy balance remain unclear; herein we investigated how Mel regulates ...

Association between serum leptin concentrations and insulin resistance: a population-based study from China. [PDF]
BACKGROUND: Insulin resistance contributes to the cardio-metabolic risk. The effect of leptin in obese and overweight population on insulin resistance was seldom reported.

Cleavage of the leptin receptor by matrix metalloproteinase-2 promotes leptin resistance and obesity in mice. [PDF]
Matrix metalloproteinase–2 inhibition rescued leptin receptor expression in the hypothalamus and reduced fat accumulation in rodent models of obesity.

Leptin resistance and hippocampal behavioral deficits. [PDF]
The 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
