Three decades ago, in a lab at The Rockefeller University, New York City, Jeffrey Friedman, MD, PhD, observed a paradox that would forever change our understanding of obesity. His subjects, a rare ...

Hormone absence or inactivity is common in congenital disease, but hormone antagonism remains controversial. Here, we characterize two novel homozygous leptin variants that yielded antagonistic ...
