Severity of Asthma Symptoms Linked to Excessive Airway Nerves, Study

A new study implicates the remodeling of nerves in the airways as a key contributor to heightened sensitivity and airway constriction in patients with asthma. The results provide new insight into a little-understood factor in the development of asthma, a condition that affects about 235 million people worldwide. The study is the first to demonstrate that inflammatory cells can alter nerve structure in the lungs to cause disease.
