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.

In Vitro primary human airway epithelial whole exhaust exposure

The method outlined in this article is a customization of the whole exhaust exposure method generated by Mullins et al. (2016) using reprogrammed primary human airway epithelial cells as described by Martinovich et al. (2017). It has been used successfully to generate recently published data (Landwehr et al. 2021). The goal was to generate an exhaust exposure model where exhaust is collected from a modern engine, real-world exhaust concentrations are used and relevant tissues exposed to assess the effects of multiple biodiesel exposures.

Fuel feedstock determines biodiesel exhaust toxicity in a human airway epithelial cell exposure model

Biodiesel is promoted as a sustainable replacement for commercial diesel. Biodiesel fuel and exhaust properties change depending on the base feedstock oil/fat used during creation. The aims of this study were, for the first time, to compare the exhaust exposure health impacts of a wide range of biodiesels made from different feedstocks and relate these effects with the corresponding exhaust characteristics.

Directing immune development to curb sky-rocketing disease

Once upon a time it was infectious diseases like polio, measles or tuberculosis that most worried parents. With these threats now largely under control, parents face a new challenge – sky-rocketing rates of non-infectious diseases such as asthma, allergies and autism.

Australian researchers join international project to curb unhealthy lifetime trajectories

Australian researchers join global effort to better understand how events during pregnancy and childhood influence the development of disease later in life.

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.
