The frontiers of xenotransplantation have been further extended with a pig-to-human lung transplant, the first time an organ that is directly exposed to the external environment – with the associated risk of respiratory pathogens – has been transplanted. The genetically modified pig lung remained viable and functional for nine days, after it was transplanted into a 39-year-old man who was declared brain dead following a hemorrhagic stroke.

Despite having lower smoking habits than other groups in the U.S., Black Americans are more likely to develop lung cancer, and their survival rates are significantly worse. What explains this disparity? Scientists at Vanderbilt University Medical Center have analyzed the genetics of their African ancestry in search of risk genes related to the disease and tobacco use. The results reveal new risk factors and confirm the presence of genetic variants that may contribute to the greater impact of lung cancer in this population.

Deficiencies in interferon-stimulated gene 15 (ISG15), a protein that normally regulates the immune response, causes mild but persistent inflammation. However, its absence also provides an unexpected advantage by increasing resistance to viral infections. Inspired by this condition and using mRNA technology, scientists at Columbia University and the Icahn School of Medicine at Mount Sinai have developed a broad-spectrum antiviral platform.

Quoted technology commercialization company Puretech Health plc is scouting for third parties to fund phase III development of deupirfenidone, after spinning the respiratory drug into a new startup, Celea Therapeutics.

Mycobacterium abscessus, a nontuberculous mycobacterium, is a significant cause of chronic pulmonary infections, particularly in individuals with compromised immune systems or structural lung conditions, such as cystic fibrosis.

Some Apple Watch users will be able to monitor their blood oxygen levels through their iPhone, thanks to a software update the company planned to issue Aug. 14. The Cupertino, Calif.-based company pulled the feature from its watches in the U.S. in 2024, following a patent dispute with Masimo Corp., of Irvine, Calif., that threatened an import ban.

Insmed Inc. CEO William Lewis said that offering two doses of Brinsupri (brensocatib) will complicate payer coverage “not at all, just the opposite. It’s going to give the flexibility to physicians to choose how they want to engage with their patients, wrestle with whatever issues may be in their minds related to safety [and] what have you.” The U.S. FDA approved Insmed’s first-in-class dipeptidyl peptidase 1 inhibitor, Brinsupri, given in 10-mg and 25-mg tablets as a once-daily treatment for noncystic fibrosis bronchiectasis in adults and children 12 and older.

Korea Disease Control and Prevention Agency (KDCA) secured 5.3 million doses of COVID-19 vaccines made by Pfizer Inc./Biontech SE and Moderna Inc., officially including the mRNA-based vaccines in the country’s national immunization program on Aug. 5.
