Sputum exosomes: promising biomarkers for idiopathic pulmonary fibrosis
Thorax, 2018 Idiopathic pulmonary fibrosis (IPF) is a progressive fibrosing interstitial lung disease of unknown aetiology which leads rapidly to death. As diagnosis of IPF is complex, we aimed to characterise microRNA (miRNA) content of exosomes from sputum of ...

Update on sputum methodology [PDF]
European Respiratory Journal, 2000 Over the past few years cellular and biochemical sputum examinations have become important instruments to assess airway inflammation. The aim of this review is to summarize new methodological developments and aspects, which are currently under investigation.

The Lancet Respiratory Medicine, 2018 Summary Background Pathogen surveillance is challenging but crucial in children with cystic fibrosis—who are often non-productive of sputum even if actively coughing—because infection and lung disease begin early in life.

PLOS ONE, 2020 Markers of lung inflammation measured directly in expectorated sputum have the potential of improving the timing of antibiotic treatment in cystic fibrosis (CF). L-Lactate might be a marker of inflammation, as it is produced from glucose by polymorphonuclear neutrophils (PMNs) in CF lungs.

Advanced Science, EarlyView.Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Frontiers in Microbiology, 2017 Mycobacterial cellular variations in growth and division increase heterogeneity in cell length, possibly contributing to cell-to-cell variation in host and antibiotic stress tolerance. This may be one of the factors influencing Mycobacterium tuberculosis

Au nanorod assembly for sensitive SERS detection of airway inflammatory factors in sputum
Frontiers in Bioengineering and Biotechnology, 2023 In this paper, we demonstrate a surface-enhanced Raman spectroscopy (SERS) biosensor based on the self-assembly of gold nanorods (AuNRs) for the specific detection of airway inflammatory factors in diluted sputum.

Advanced Science, EarlyView.An integrated Human Airway Microbiome Gene Catalog (iHAMGC) is constructed from 12,273 metagenomic airway samples, providing a high‐resolution reference of respiratory microbial genes. The catalog enables systematic exploration of taxonomic and functional variation across airway niches and geographic regions, revealing site‐specific and region ...
