Genes that produce proteins responsible for the sticky qualities of mucus – known as mucins – have evolved from unrelated genes again and again in mammals, according to a study published in Science ...

In the gastrointestinal tract, mucus forms an abundant and continuous layer that lines the apical surface of intestinal epithelial cells. This mucus is predominantly produced and secreted by ...

The mucosal tissues of the gastrointestinal, respiratory, reproductive, and urinary tracts, and the surface of the eye present an enormous surface area to the exterior environment. All of these ...

From the slime coating slugs to the saliva in our mouths, many slippery bodily fluids contain mucus. So how did this marvel of biology evolve? In mammals, the answer is many times, and often in a ...

Mucus is continuously swept from distal to proximal airways. In the most distal bronchioles, epithelial cells are cuboidal and do not produce mucin (bottom box), and bronchiolar patency is stabilized ...
