Leptin resistance: underlying mechanisms and diagnosis

Diabetes Metab Syndr Obes. 2019 Jan 25:12:191-198. doi: 10.2147/DMSO.S182406. eCollection 2019.


Leptin and its receptors have been identified as key regulators of body weight and energy homeostasis. A decrease in tissue sensitivity to leptin leads to the development of obesity and metabolic disorders, such as insulin resistance and dyslipidemia. Mechanisms underlying the development of leptin resistance include mutations in the genes encoding leptin and its receptors, as well as proteins involved in self-regulation of leptin synthesis and blood-brain barrier permeability. Leptin resistance encompasses a complex pathophysiological phenomenon with a number of potential research lines. In this review, we analyze the existing data on the methods used to diagnose leptin resistance.

Keywords: leptin; leptin resistance; soluble leptin receptor.
