A vaccine usually trains your immune system to recognize one target. Here, the target is basically “anything that doesn’t ...

Researchers at the Francis Crick Institute and AlveoliX have developed the first human 'lung-on-chip' model using stem cells taken from only one person. These chips simulate breathing motions and lung ...

Human mini-lungs grown by University of Manchester scientists can mimic the response of animals when exposed to certain nanomaterials. The study at the University’s NanoCell Biology Lab at the Centre ...

Though we’ve now been living with SARS-CoV-2, the virus that causes COVID-19, for close to five years, many aspects of its biology and pathology remain mysterious. This is not helped by the fact that ...

How do pathogens invade the lungs? Using human lung microtissues, a team has uncovered the strategy used by a dangerous pathogen. The bacterium targets specific lung cells and has developed a ...

UCLA researchers have successfully grown miniature lungs from stem cells — complete with their own functioning blood vessel networks. The groundbreaking work, detailed in Cell, marks the first time ...

A newly identified lung cell “switch” could help doctors unlock the lungs’ natural ability to heal themselves.

Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing. For many years, ...

Stanford Medicine researchers have developed an experimental nasal vaccine that shielded mouse lungs for at least three months against a striking range of respiratory threats, from SARS-CoV-2 and ...
