Journal ArticleDOI

Reinhard Manzenreiter,Ferry Kienberger,Veronica Marcos,Kurt Schilcher,Wolf Dietrich Krautgartner,Astrid Obermayer,Marlene Huml,Walter Stoiber,Andreas Hector,Matthias Griese,Matthias Hannig,Michael Studnicka,Ljubomir Vitkov,Ljubomir Vitkov,Dominik Hartl +14 more
TL;DR: It is suggested that excessive NET formation represents the major factor underlying the gel-like structure of CF sputum and provide evidence that CF-NETs contain ectosome-like structures that could represent targets for future therapeutic approaches.
Journal ArticleDOI
The Role of Reactive Oxygen Species (ROS) in the Formation of Extracellular Traps (ETs) in Humans
TL;DR: It is concluded that ROS interact with ETosis in a multidimensional manner, with influence on whether ETosis shows beneficial or detrimental effects, and the present evidence for ROS-independent ETosis is analyzed.
Journal ArticleDOI
Neutrophil extracellular trap (NET) formation characterises stable and exacerbated COPD and correlates with airflow limitation
Fikreta Grabcanovic-Musija,Astrid Obermayer,Walter Stoiber,Wolf-Dietrich Krautgartner,Peter Steinbacher,Nicole Winterberg,Arne C. Bathke,Michaela Klappacher,Michael Studnicka +8 more
TL;DR: NET formation is not confined to exacerbation but also present in stable COPD and correlates with the severity of airflow limitation, infering that NETs are a major contributor to chronic inflammatory and lung tissue damage in COPD.
Journal ArticleDOI
New aspects on the structure of neutrophil extracellular traps from chronic obstructive pulmonary disease and in vitro generation.
Astrid Obermayer,Walter Stoiber,Wolf-Dietrich Krautgartner,Michaela Klappacher,Barbara Kofler,Peter Steinbacher,Ljubomir Vitkov,Fikreta Grabcanovic-Musija,Michael Studnicka +8 more
TL;DR: The structure of NETs found in induced sputum of patients with acutely exacerbated chronic obstructive pulmonary disease (COPD) is analysed using confocal laser microscopy and electron microscopy to conclude that NETosis is an integral part of COPD pathology and that release of ‘beads-on-a-string’ DNA studded with non-citrullinated histones is a common feature of in vivo NETosis.
Journal ArticleDOI
MyoD and Myogenin expression during myogenic phases in brown trout: a precocious onset of mosaic hyperplasia is a prerequisite for fast somatic growth.
Peter Steinbacher,John R. Haslett,Astrid Obermayer,Julia Marschallinger,Hans-Christian Bauer,Alexandra Maria Sänger,Walter Stoiber +6 more
TL;DR: Molecular techniques are used to provide a comprehensive characterization of MyoD and Myogenin expression during myogenic cell activation in embryos and larvae of brown trout, a fast‐growing salmonid with exceptionally large embryos, and suggest that Pax7 is expressed in myogenic progenitor cells that account for second‐ and third‐phase myogenesis.
