New Research May Explain Why Obese People Have Higher Rates of Asthma, Columbia University Medical Center Study

A new study led by Columbia University Medical Center (CUMC) researchers has found that leptin, a hormone that plays a key role in energy metabolism, fertility, and bone mass, also regulates airway diameter. The findings could explain why obese people are prone to asthma and suggest that body weight–associated asthma may be relieved with medications that inhibit signaling through the parasympathetic nervous system, which mediates leptin function. The study, conducted in mice, was published in the online edition of the journal Cell Metabolism.
