Pulmonary alveolar proteinosis is a rare disorder in which lipoproteinaceous material accumulates within alveoli. 1 The clinical course of the disease is variable, ranging from respiratory failure to ...

The pulmonary alveolar epithelium consists of alveolar type I (AT1) and alveolar type II (AT2) cells. Interactions between these two cell types are necessary for alveolar homeostasis and remodeling.

Macrophages are highly variable, and their ontogeny and functions depend on the particular organ in which they reside and on any ongoing disease processes. Lung macrophages are critically important to ...

Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system. People ...

Alveoli in the salivary glands of unfed Amblyomma americanum (L.) females (postnymphal ticks that had not yet taken a bloodmeal as an adult) were studied. As in other species of female ixodid ticks, ...
