When human viruses were tested, both attached strongly to the trachea and bronchi, but virus binding to the bronchioles and alveoli (deeper within the lung) was less abundant in comparison.

Human lungs are spongy vessels made up of millions of microscopic, balloon-shaped air sacs called alveoli, the workhorse of the respiratory system where the exchange of gases takes place. Trachea ...

In ureaplasma-positive babies with bronchopulmonary dysplasia, the tracheal aspirate fluid included elevated levels of inflammatory mediators, including interleukin (IL)-1, IL-6, and IL-8, and ...

July 26, 2012— -- The first child in history to receive a trachea fashioned by his own stem cells has shown remarkable progress since the initial transplant two years ago, marking a new ...
