Mucociliary Clearance in Bronchiectasis

An International Journal Clinical Rhinology, 2016
ABSTRACT Bronchiectasis is a chronic lung disease, defined pathologically as irreversible dilatation of the bronchi. There is ineffective clearance of pulmonary secretions because of damage to the cilia. The nasal mucociliary clearance was studied using the saccharine method in 75 patients of bronchiectasis and the results were compared with those of ...

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.

A mechanism of airway injury in an epithelial model of mucociliary clearance

Respiratory Research, 2004
We studied the action of sodium metabisulphite on mucociliary transport in a frog palate epithelial injury model, hypothesizing that it may be useful for the study of mechanisms of airway injury.

Effect of Dupilumab on Airway Inflammation in Patients With Persistent Asthma

Allergy, EarlyView.
EXPEDITION (NCT02573233) assessed the effects of dupilumab on airway inflammation in patients with persistent asthma using bronchoscopy and gene expression analysis. Dupilumab showed no appreciable effect on inflammatory cell types in biopsies or BALF samples.

The discovery and development of ensifentrine: A novel inhaled dual PDE3/4 inhibitor having ‘bifunctional’ bronchodilator and anti‐inflammatory activity

British Journal of Pharmacology, EarlyView.
Abstract Ensifentrine (formerly called RPL 554) is a novel, first in class, inhaled bifunctional dual PDE3/4 inhibitor for the treatment of chronic respiratory diseases. Ensifentrine exhibits both bronchodilation via PDE3 inhibition and anti‐inflammatory activity via PDE4 inhibition.

The lung is more than an organ of gas exchange: immunocompetency, platelets and implications for drug discovery

British Journal of Pharmacology, EarlyView.
Abstract The lungs have for a long time been recognised as having pharmacological significance as a specific organ to modulate the pharmacokinetics of endogenous substances needed to maintain homeostasis. The lungs are therefore the site of action of certain drugs that act on these homeostatic processes, resulting in systemic effects on the ...

Reconstruction of native cellular microanatomy in a novel bioengineered full thickness human nasal mucosal construct

Journal of Anatomy, EarlyView.
Bioengineered tissue constructs are vital technologies employed in in vitro testing of both fundamental biological principles and industrial screening practices. Current approaches to modelling the nasal mucosa in vitro are not representative and are associated with limitations that impact their reliability and predictive value.

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

RBL2 represses the transcriptional activity of Multicilin to inhibit multiciliogenesis

Cell Death and Disease
A core pathophysiologic feature underlying many respiratory diseases is multiciliated cell dysfunction, leading to inadequate mucociliary clearance. Due to the prevalence and highly variable etiology of mucociliary dysfunction in respiratory diseases, it

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.
