Scientists discover how mucus protein emerges to disrupt airways of individuals with lung conditions

Mucus is an essential protective layer of gel-like liquid composed largely of proteins called mucins throughout our airways. One of them, called MUC5B, is crucial for the innate defense against the various things we inhale.

Researchers discover new set of signals that control production of goblet cells in the lung

Proper lung function relies on the precise balance of specialized epithelial cells (cells that line the surfaces of the body) that coordinate functions to maintain homeostasis.

Study: E-cigarette users have 43% increased risk of developing respiratory disease

A growing body of evidence points to the health risks of using e-cigarettes (or "vaping"). But because e-cigarettes are marketed as a less harmful alternative to traditional cigarettes, it has been difficult to tell whether the association between vaping and disease is just a matter of smokers switching to vaping when they start experiencing health issues.

Undersized airways increase risk of COPD regardless of smoking habits

A new study of lung anatomy may explain why 1 in 4 cases of COPD--a lung disease most often linked to smoking--occur in people who have never smoked, a fact that has long perplexed researchers.

Expert offers COVID-19 guidance for patients with COPD

Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a chronic lung disease that makes it hard to breathe. The disease affects millions of Americans and is the fourth leading cause of disease-related death in the U.S. People with COPD have a higher risk of more severe illness from COVID-19 due to their existing lung problems.

UK study highlights importance of breathing tests in the assessment of COPD

A UK study of patients participating in low-dose CT lung cancer screening highlights the importance of spirometry (breathing tests) in the assessment of possible chronic obstructive pulmonary disease (COPD), and demonstrates that over-reliance on radiological changes alone may result in detection of clinically insignificant disease.

Long-term air pollution makes rhinitis symptoms worse

A new study published in the Journal of Allergy and Clinical Immunology reports that people exposed to polluted air out of doors show more severe symptoms of rhinitis, a very common condition also called a cold. This is due to an inflammation of the nasal mucosa.

Researchers report evidence linking 'vaping' to increased likelihood of asthma and COPD

Using data from a large federal government telephone survey of adults, Johns Hopkins Medicine researchers report evidence that inhaling heated tobacco vapor through e-cigarettes was linked to increased odds of asthma and chronic obstructive pulmonary disease, conditions long demonstrated to be caused by smoking traditional, combustible cigarettes.
