ScienceDaily (Aug. 13, 2009) — hronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them. Work by scientists at the European Molecular Biology Laboratory (EMBL) and its Molecular Medicine Partnership Unit (MMPU) with the University of Heidelberg, Germany, has shed new light on the underlying disease process of emphysema using a technique which could in future be adapted for use in diagnosis.
