The Lungs – A direct connection to the outside world
The Inflammation Research Excellence Cluster concentrates particularly on the most common chronic inflammatory lung diseases, which include COPD and asthma. COPD (chronic obstructive pulmonary disease) is characterized by coughing, shortness of breath during exercise and a marked deterioration in exhalation. Smoking, pollution, frequent respiratory infections in childhood and a genetic predisposition are all influences which have been verified as causes. Typical symptoms of asthma are a hypersensitivity to ordinarily innocuous stimuli (bronchial hyperresponsiveness) as well as a narrowing of the air passages through an increased formation of mucous, and spasms of the respiratory muscles, which to some extent can lead to seizure-like respiratory distress. Both diseases, COPD as well as asthma, are characterized by inflammatory reactions, differentiated by the profiles of the inflammatory cells which have immigrated to the lungs. The number of those affected with chronic inflammatory lung diseases is increasing worldwide. In Germany alone, several million people suffer from the diseases.
Focus: Experimental Pneumology
The field of “Experimental Pneumology” was established at the Research Center Borstel with substantial support from the Inflammation Research Excellence Cluster. Professor Fehrenbach was appointed as head of “Experimental Pneumology” in order to research with his team the interaction of inflammatory (e.g. lymphocytes, granulocytes) and structure-forming cells (e.g. epithelial, connective tissue, muscular) as well as the resulting correlations between structural and functional changes of inflamed air passages in asthma and COPD. In addition, the team addresses the question as to what extent the lungs’ ability to regenerate themselves in tissue-destoying processes, such as those in COPD that result in the development of emphysema, could be used for therapeutic purposes.
