Leptin Signaling in Lean and Obese Humans
Leptin Signaling in Humans

Obesity does not respond to high circulating levels of the hormone leptin. This study is aiming at finding out why this happens and open new avenues for treatment of obesity.

Ex vivo and in vitro identification and study of leptin signaling pathways in commercially available cell lines serum/ plasma samples and discarded tissues from humans.
