The results could help guide the design of new vaccines for the disease.

The immune cells facilitate healing, but they may also help tumors metastasize to the lungs after injury, a study in mice finds.

Researchers show that both mice and pigs are capable of oxygenating their blood via the colon—a capacity that, if shared by humans, could be leveraged in the clinic to minimize the need for mechanical ventilation.

In humans, higher oxygen levels during ventilation are tied to an altered bacterial composition in the lungs, and mouse experiments show a causative link.

A pathologist describes his observations from examining the bodies of those who succumbed to the coronavirus.

The cholesterol-lowering drugs quell inflammation and reverse endothelial tissue damage, hints that they might curb the body’s excessive immune response to SARS-CoV-2 infection.

Lesions in the lungs of patients with pneumonia caused by a SARS-CoV-2 infection are distinct from those caused by bacteria.

Super-resolution imaging identifies abnormalities in the hair-like protrusions on a cell’s surface and may help facilitate earlier detection of primary ciliary dyskinesia.

There is little evidence that antihypertensive drugs worsen COVID-19, and scientists are instead exploring the idea that such medications—or their downstream effects—may actually alleviate symptoms.

Through his studies on cancer-causing viruses, the University of California, Los Angeles, professor has helped develop lifesaving treatments.

Unable to break through the water’s surface, tadpoles have a unique workaround for breathing air.

Researchers mined an electronic cigarette users’ online discussion forum and found reports of headaches, coughing, itching, and throat pain.

The low-carb, high-fat diet increases the presence of gamma-delta T cells in the animals’ lungs, improving a mucus barrier against the virus.

In light of recent reports of electronic-cigarette–related illness and death, UNC Chapel Hill professor Robert Tarran discusses the dangerous effects of e-liquids on the lungs.

Firefighters who didn’t develop obstructive airway disease after the World Trade Center attacks had higher levels of omega-3 fatty acids and other factors that hint at possible protective effects of diet.

The redondoviruses, named for their circular DNA, inhabit the human respiratory tract and may be linked to disease.

A specific type of lung cell withstands flu infection by doubling down on DNA repair.

Most of the genetic alterations are harmless, but some may contribute to cancer.

CRISPR reagents injected into the amniotic fluid inactivated a gene in the fetuses that would normally cause lung disease and kill the mice a few hours after birth.
