  3. Jeffrey M. Friedman Professor; Investigator, HHMI. The application of modern methods in genetics has led to the identification of a new hormone, leptin, that regulates body weight. Leptin is an adipose tissue hormone that interacts with receptors in the brain to regulate food intake, energy expenditure and other neuroendocrine systems.

  4. The team explores the neural mechanisms by which leptin acts on the brain to mediate its effects, while also seeking to identify other key regulators of body weight.
