Webb11 nov. 2003 · The walls of the larger airways contain glands composed of two secretory cell types: the serous and the mucous cell. The epithelium of the distal airways, the bronchioles, consists mainly of ciliated and Clara cells. The alveoli are covered by alveolar epithelial cells, types I and II. WebbObliterative bronchiolitis (OB) is the most important cause of graft dysfunction post‐lung transplantation. It is likely that the small airway epithelium is a target of the alloimmune response, and that epithelial integrity is a crucial determinant of airway patency. Our goals are to elucidate epithelial cell kinetics in the heterotopic mouse trachea model and to …
WebbNeurotrophins (NTs) are a group of soluble growth factors with analogous structures and functions, identified initially as critical mediators of neuronal survival during development.

The flow of ions through the epithelium is followed by water into the intestinal lumen. Analysis of published RNA-seq data showed that Cftr is expressed in several cell types in the small intestinal epithelium, including goblet cells at the base of the crypt (Fig. 3, E and F).
