Coronavirus particles (small, spiky spheres) coat a human lung cell and its hairlike cilia in this scanning electron micrograph (left; higher-resolution view at right). C. Ehre/ NEJM 2020 ...

Images show that the coronavirus clears the respiratory tract of hairlike structures called cilia, which keep foreign objects out of the lungs.

Smoking can turns your lungs, black, inflated, and inflamed. But quitting can reverse some of this damage, even if you’ve smoked for several years.

COPD-like in vivo conditions can be imitated by treating the lung SAEC model with IL-13 and analyzing the cilia beat frequency to predict drug efficacy clinical translation.

New Image of Coronavirus Released as Seen up Close Inside Human Lungs | SEE PIC The images show infected ciliated cells with strands of mucus (yellow) attached to cilia tips (blue).

The noodle-like projections in the images are cilia, or hair-like structures on the surface of some airway cells. (Image credit: The New England Journal of Medicine ©2020.) ...

The first image of the structures that power human cilia – the tiny, hairlike projections that line our airways – has been produced by a team involving UCL researchers and could lead to much ...

Schematic of the lung epithelium: The figure shows how cells with cilia (green) work together with mucus-forming cells (yellow, purple) to effectively remove pathogens from the lung.

Anewly developed imaging toolbox may improve the detection of primary ciliary dyskinesia, a genetic lung disorder characterized by impaired motility of the cilia, the slender organelles protruding ...

Damage to the cilia in your lungs can also make it harder for them to clear out things like mucus. Smokers are more likely to get serious lung conditions such as pneumonia.
