A study published in Cell Reports reveals that LPS protects against developing asthma when combined with allergens containing cysteine protease enzymatic activity, but promotes development when paired with allergens lacking this enzyme. This protective effect relies on the production of GM-CSF by non-classical monocytes.
A new study estimates that nitrogen dioxide from traffic pollution contributes to nearly 2 million cases of pediatric asthma annually. Cleaner air in urban areas has led to a decline in these cases, but more work is needed to curb harmful emissions.
A recent study published in The Lancet Planetary Health found that approximately 2.5 billion people worldwide lived in areas exceeding the WHO guideline for annual average PM2.5 exposure, resulting in an excess of 1.8 million deaths. Additionally, nearly 2 million asthma cases among children were attributable to NO2 pollution in 2019.
