In utero exposure to low dose arsenic via drinking water impairs early life lung mechanics in mice

All alterations to lung mechanics following in utero arsenic exposure were recovered by adulthood.

The mechanism of deep inspiration-induced bronchoprotection: Evidence from a mouse model

In healthy individuals, deep inspirations (DIs) taken prior to a bronchial challenge reduce the bronchoconstrictor response, which is termed...

Acute diesel exhaust particle exposure increases viral titre and inflammation associated with existing influenza

Exposure to diesel exhaust particles (DEP) is thought to exacerbate many pre-existing respiratory diseases.

Sensitizing and Th2 Adjuvant Activity of Cysteine Protease Allergens

Here, we report on a model that does not use Th2-skewing adjuvants and yet achieves sensitization solely via the nasal mucosa.

Physiological and inflammatory responses in an anthropomorphically relevant model of acute diesel exhaust particle exposure are sex and dose-dependent

Diesel exhaust particles (DEP) are an important contributor to suspended particulate matter (PM) in urban areas. While epidemiological evidence exists for a...

Azithromycin inhibits mucin secretion, mucous metaplasia, airway inflammation, and airways hyperresponsiveness in mice exposed to house dust mite extract

Excessive production, secretion, and retention of abnormal mucus is a pathological feature of many obstructive airways diseases including asthma. Azithromycin is an antibiotic that also possesses immunomodulatory and mucoregulatory activities, which may contribute to the clinical effectiveness of azithromycin in asthma.

Toxicity of different biodiesel exhausts in primary human airway epithelial cells grown at air-liquid interface

Biodiesel is created through the transesterification of fats/oils and its usage is increasing worldwide as global warming concerns increase. Biodiesel fuel properties change depending on the feedstock used to create it.

Growth of the airway smooth muscle layer from late gestation to childhood is mediated initially by hypertrophy and subsequently hyperplasia

The airway smooth muscle (ASM) layer thickens during development. Identifying the mechanism(s) for normal structural maturation of the ASM reveals pathways susceptible to disease processes. This study characterized thickening of the ASM layer from foetal life to childhood and elucidated the underlying mechanism in terms of hypertrophy, hyperplasia and extracellular matrix (ECM) deposition.

Exacerbation of chronic cigarette-smoke induced lung disease by rhinovirus in mice

A significant proportion of chronic obstructive pulmonary disease exacerbations are strongly associated with rhinovirus infection (HRV). In this study, we combined long-term cigarette smoke exposure with HRV infection in a mouse model.

Long-term exposure of mice to 890 ppm atmospheric CO2 alters growth trajectories and elicits hyperactive behaviours in young adulthood

Atmospheric carbon dioxide (CO2) levels are currently at 418 parts per million (ppm), and by 2100 may exceed 900 ppm. The biological effects of lifetime exposure to CO2 at these levels is unknown. Previously we have shown that mouse lung function is altered by long-term exposure to 890 ppm CO2. Here, we assess the broader systemic physiological responses to this exposure.
