“Leptin and leptin receptor expression in asthma” [PDF]
Journal of Allergy and Clinical Immunology, 2009 Background: The adipokine leptin is a potential new mediator for bronchial epithelial homeostasis. Asthma is a chronic inflammatory disease characterized by airway remodeling that might affect disease chronicity and severity. TGF-b is a tissue growth

Structural insights into the mechanism of leptin receptor activation [PDF]
Nature Communications, 2023 Leptin is an adipocyte-derived protein hormone that promotes satiety and energy homeostasis by activating the leptin receptor (LepR)–STAT3 signaling axis in a subset of hypothalamic neurons.

Melanocortin receptors in leptin effects [PDF]
Nature, 1997 Leptin acts on the central nervous system to cause a reduction in food intake and body weight1,2. The melanocortin system in the brain is also implicated in energy homeostasis, with agonists of the melanocortin-4 (MC4) receptor reducing food intake3 and targeted mutation of the MC4 receptor causing obesity4.

Leptin-Activity Modulators and Their Potential Pharmaceutical Applications
Biomolecules, 2021 Leptin, a multifunctional hormone primarily, but not exclusively, secreted in adipose tissue, is implicated in a wide range of biological functions that control different processes, such as the regulation of body weight and energy expenditure ...

European Journal of Medical Research, 2010 Leptin or obesity receptor (Ob-R) is a member of class I cytokine receptor family. Ob-R, expressed in six isoforms, is the product of alternative RNA splicing of db gene. According to its structural differences, the receptor's isoforms are divided into three classes: long, short, and secretory isoforms.

The immunohistochemical expression of leptin in lymph node metastasis from laryngeal squamous cell carcinoma (SCC) [PDF]
, 2020 Introduction: Leptin is a proteohormone produced predominantly by white adipocytes and primarily known for its key role in the control of food intake and sense of satiety.
