Leptin

leptin
This gene encodes a protein that is secreted by white adipocytes, and which plays a major role in the regulation of body weight. This protein, which acts through the leptin receptor, functions as part of a signaling pathway that can inhibit food intake and/or regulate energy expenditure to maintain constancy of the adipose mass. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis and wound healing. Mutations in this gene and/or its regulatory regions cause severe obesity, and morbid obesity with hypogonadism. This gene has also been linked to type 2 diabetes mellitus development.

Papers on leptin
Association of the leptin receptor Gln223 Arg polymorphism with lipid profile in obese Pakistani subjects.
New
Hasnain et al., Lahore, Pakistan. In Nutrition, 30 Sep 2015
CONCLUSIONS: The LEPR Gln223 is associated with obesity, lipid parameters, and plasma glucose in all subjects, with weight, body mass index, and systolic and diastolic blood pressure only in obese subjects, but showed no association with leptin, insulin, and HOMA-IR in a Pakistani study group.

Charli et al., Ecatepec, Mexico. In J Endocrinol, 31 Aug 2015
The activity of TRH neurons is regulated by nutritional status through neurons of the arcuate nucleus, which sense metabolic signals such as circulating leptin levels.
