Mathematical Modeling of Mucociliary Clearance: A Mini-Review

Cells, 2019
Mucociliary clearance is an important innate host defense of the mammalian respiratory system, as it traps foreign substances, including pollutants, pathogens, and allergens, and transports them out of the airway.

The Impact of Environmental Pollution and Climate Change on Allergic Rhinitis and Lung Diseases

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Environmental pollution and climate change seriously affect human health, leading to the onset and exacerbation of chronic respiratory diseases, such as allergic rhinitis and lung diseases. Over the past several decades, increasing air pollution and environmental exposure owing to global urbanization, industrialization, and rapid economic ...

Advances in bronchiectasis:endotyping, genetics, microbiome, and disease heterogeneity [PDF]

, 2018
Bronchiectasis is characterised by pathological dilation of the airways. More specifically, the radiographic demonstration of airway enlargement is the common feature of a heterogeneous set of conditions and clinical presentations.

Identification and Validation of Biomarkers in Chronic Rhinosinusitis With Nasal Polyps and Study of Their Associated Mechanisms

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Research Progress on Upper Airway Cough Syndrome

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Upper airway cough syndrome (UACS) has been identified as a significant contributor to chronic cough in various national guidelines. However, the complexity of its pathogenesis, the lack of clarity surrounding its diagnostic criteria, and its overlap with other etiologies of chronic cough present considerable challenges in both diagnosis and ...

A new paradigm in respiratory hygiene: modulating respiratory secretions to contain cough bioaerosol without affecting mucus clearance

BMC Pulmonary Medicine, 2007
Background Several strategies and devices have been designed to protect health care providers from acquiring transmissible respiratory diseases while providing care. In modulating the physical characteristics of the respiratory secretions to minimize the

Club Cells in Nasal Epithelial Repair: Insights From an IL‐13‐Induced Inflammatory Model

Allergy, EarlyView.
Four inflammatory endotypes of CRSwNP, defined by eosinophil and neutrophil infiltration, show distinct patterns of basal, club, ciliated, and goblet cell expression in nasal epithelium. Using an ALI‐HNECs model, we demonstrate that IL‐13 impairs mucociliary function by promoting club‐to‐goblet cell differentiation while inhibiting club‐to‐ciliated ...

Elevated CO2 and Temperature Alter Grass Pollen's Ability to Modify Transcriptome and Function of the Nasal Epithelium

Allergy, EarlyView.
We exposed human nasal epithelial tissues to pollen from grasses grown under different climate treatments (temperature and CO2). Pollen weakened epithelial tight junctions and altered cytokine‐related gene expression, with similar protein‐level effects.

Astodrimer sodium nasal spray forms a barrier to SARS-CoV-2 in vitro and preserves normal mucociliary function in human nasal epithelium

Scientific Reports
COVID-19 remains a severe condition for many including immunocompromised individuals. There remains a need for effective measures against this and other respiratory infections, which transmit via virus-laden droplets that reach the nasal or oral mucosae.
