Researchers have discovered a protein produced by nervous system may be key to treating inflammatory diseases like asthma, allergies, chronic fibrosis and chronic obstructive pulmonary disease (COPD).

Stiff collagen and stretchy elastin fibers packed together in rows allow the respiratory system to stretch and snap back into shape. Scientists previously thought these fibers govern the mechanics of the airways due to their composition. New research has instead observed that differences in the shape and form of tissue fibers influence respiratory elasticity. These findings will help scientists better understand lung diseases, from chronic diseases like COPD to the lung ailment associated with vaping.

New research shows that the asthma drug benralizumab failed to decrease annual COPD exacerbation rates for patients with moderate to very severe COPD, a history of frequent moderate and/or severe exacerbations, and eosinophilic inflammation.

Researchers have found a novel, pathogenic entity that is a fundamental link between chronic inflammation and tissue destruction in lungs of patients with COPD. These exosomes from activated neutrophils caused COPD damage when they were instilled into the lungs of healthy mice. Remarkably, neutrophil exosomes from the lung fluids of human patients with COPD and neonates with bronchopulmonary dysplasia also caused COPD lung damage when put into the lungs of healthy mice.

E-cigarette vapor boosts the production of inflammatory chemicals and disables key protective cells in the lung that keep the air spaces clear of potentially harmful particles, reveals a small experimental study.
