Leptin is a neuroendocrine hormone secreted from adipose tissue that plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism. Leptin is one of the most important adipose derived hormones.1 It interacts with six types of receptors and once it binds to OB-Receptor it activates the stat3, which is phosphorylated and travels to the nucleus to effect changes in gene expression. One of the main effects on gene expression is the down-regulation of the expression of endocannabinoids.2 High leptin levels are associated with psoriasis.3

Biological Activity
Leinco's Mouse Leptin has been shown to be biologically active in two different mouse obesity models, ob/ob and NZO. Both strains of mice were treated via intraperitoneal injection once daily at a dose of 5 µg Leptin/gm of body weight for 14 days. Significant effects on body weight, food consumption, and plasma glucose levels were observed compared to saline-treated controls.
