Mucous metaplasia of the pleura.

Mucous metaplasia of the pleura.

A case of mucous metaplasia of mesothelium in an 80 year old woman is described. Its cause is unknown, but it is important not to confuse it with secondary tumour.

The Role of Atoh1 in Mucous Cell Metaplasia

A key issue in otitis media is mucous cell metaplasia which is responsible for mucous hypersecretion and persistence of the disease. However, little is known about the molecular mechanisms of mucous cell metaplasia in otitis media. Numerous studies of intestinal epithelial homeostasis have shown that Atonal homolog 1 (Atoh1), a basic helix-loop-helix (bHLH) transcription factor, is essential fo...

Immunogenetic programs for viral induction of mucous cell metaplasia.

Mucous secretions are frequently implicated in the morbidity and mortality associated with respiratory illness and airway disease, but we still do not understand precisely how these secretions develop or how to control them. A likely possibility is that the increased mucus is a consequence of overproduction and subsequent secretion in the setting of mucous cell metaplasia. In that regard, airwa...

Mucous Metaplasia and Airways Neonatal Rhinovirus Infection Induces

Notch signaling promotes airway mucous metaplasia and inhibits alveolar development.

The airways are conduits that transport atmospheric oxygen to the distal alveolus. Normally, airway mucous cells are rare. However, diseases of the airway are often characterized by mucous metaplasia, in which there are dramatic increases in mucous cell numbers. As the Notch pathway is known to regulate cell fate in many contexts, we misexpressed the active intracellular domain of the mouse Not...
