Cytologic preparations of bronchoalveolar-lavage fluid from two patients show “foamy” alveolar macrophages (Panel B; buffered eosin and azure B, ×480). Comparison with the brown-staining red ...

The accumulated lipids make the macrophages bloated and foamy. "We can observe this phenomenon in patients with pulmonary alveolar proteinosis (PAP). They suffer from shortness of breath ...

Cells taken from the lungs of people with chronic obstructive pulmonary disease (COPD) have a larger accumulation of ...

Scientists have discovered that people with COPD have lung cells that contain over three times as much soot-like carbon as ...

Alveolar macrophages, a type of immune cell resident in the lungs, are scavengers, first-line defenders against pathogens and inhaled environmental particles responsible for clearing out debris.

Researchers at the University of Liège (Belgium) have discovered a new population of macrophages, important innate immune cells that populate the lungs after injury caused by respiratory viruses.

The accumulated lipids make the macrophages bloated and foamy. "We can observe this phenomenon in patients with pulmonary alveolar proteinosis (PAP). They suffer from shortness of breath, an impaired ...

Cells called alveolar macrophages help clear the surfactant and stop it from building up. In most cases of pulmonary alveolar proteinosis in adults, the cause is thought to be a problem with ...
