Obesity hormone tackles wound healing

In 1995, the media hailed the newly discovered protein leptin as the “obesity hormone” because it seemed to regulate the amount of fat stored by a body.

Leptin seems to play a part in immunity, puberty, reproduction, and, according to a study in the January Endocrinology, wound healing.
