Abstract
Desmosine and isodesmosine (DID) are elastin-specific crosslinking amino acids that play a critical role in maintaining the structural integrity of elastic fibers, and their levels in body fluids may serve as biomarkers for alveolar wall injury. To support this concept, we present studies demonstrating the use of DID to detect elastic fiber damage that reflects distention and the rupture of airspaces. The emergence of airspace enlargement may be modeled by a percolation network describing the effect of changing proportions of intact and weak elastic fibers on the transmission of mechanical forces in the lung. Following the unraveling and fragmentation of weakened elastic fibers, the release of DID may correlate with an increasing alveolar diameter and provide an endpoint for clinical trials of novel agents designed to treat pulmonary emphysema. The limitations of the DID measurements related to specificity and reproducibility are also addressed, particularly regarding sample source and analytical techniques. Standardizing protocols to isolate and quantify DID may increase the use of this biomarker for the early detection of alveolar wall injury, which permits timely therapeutic intervention.

期刊介绍:
Diagnostics (ISSN 2075-4418) is an international scholarly open access journal on medical diagnostics. It publishes original research articles, reviews, communications and short notes on the research and development of medical diagnostics. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodological details must be provided for research articles.
