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.

Leptin and Cognition [PDF]

open access: yesDementia and Geriatric Cognitive Disorders, 2012
Leptin has been reported to have positive effects on cognition but has not been studied in a population-based sample or stratified by race or gender.Leptin and fat mass were measured in 2,731 subjects, including 50% African Americans. Eight years later, subjects were administered the Montreal Cognitive Assessment (MoCA).

Generation of Neural Organoids and Their Application in Disease Modeling and Regenerative Medicine

open access: yesAdvanced Science, EarlyView.
Neural organoids provide a versatile platform for neurological research. Advances in organoid technology have partially achieved human neural tissue complexity in terms of tissue structure, cell diversity, and neural signaling, offering insights into neural disorders and regenerative strategies. Technology advances from biomaterials, bio‐manufacturing,

Leptin: Is It Thermogenic? [PDF]

open access: yesEndocrine Reviews, 2019
Abstract Animals that lack the hormone leptin become grossly obese, purportedly for 2 reasons: increased food intake and decreased energy expenditure (thermogenesis). This review examines the experimental evidence for the thermogenesis component. Analysis of the data available led us to conclude that the reports indicating hypometabolism

LEPTIN RESISTANCE AND TYPE 2 DIABETES

open access: yesInternational Journal of Medicine and Medical Research, 2017
Leptin is one of adipocyte-secreted hormones. It signals to the brain and other tissues about the status of body energy reserves. Circulating leptin levels are directly proportional to the amount of the body fat.

Hyperleptinemia is required for the development of leptin resistance. [PDF]

open access: yesPLoS ONE, 2010
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.

Leptin and reproduction [PDF]

open access: yesProceedings of the Nutrition Society, 1998
Fertility in mammals requires adequate nutrition and a certain reserve of metabolic fuel (Van Der Spuy, 1985). Individuals experiencing wasting diseases (e.g. insu- lin-dependent diabetes), severe dietary restriction (e.g. anorexics), or who are high-performance athletes (e.g.

Leptin Aggravates Thoracic Aortic Dissection Through Impairment of Energy Metabolism in Nrip2+ Smooth Muscle Cells

open access: yesAdvanced Science, EarlyView.
Epidemiological data confirm obesity elevates thoracic aortic dissection (TAD) risk. Patient analyses implicate hyperleptinemia, where leptin binding to vascular smooth muscle cell (VSMC) receptors triggers Socs3‐mediated suppression of Stat5a transcriptional activity.

Expression of leptin and its receptor in female breast cancer in relation with selected apoptotic markers.

open access: yesFolia Histochemica et Cytobiologica, 2008
Leptin and its receptor may be engaged in pathogenesis of breast cancer among various human tumors. In vitro investigations showed leptin-mediated escalation of estrogen synthesis and boosted activity of estrogen receptor ERalpha.
