An enzyme that activates cell death could be targeted to avoid the inflammation and lung lesions caused by influenza A virus (IAV). A collaborative study demonstrated that an inhibitor of receptor-interacting serine/threonine-protein kinase 3 (RIPK3) blocked necroptosis in infected alveolar epithelial cells and prevented the consequences in the lungs of severe disease.

SARS-CoV-2 could proliferate in the lungs causing severe COVID-19 through a special type of immune cell. A group of scientists from Stanford University observed how this coronavirus infected interstitial macrophages through a CD209 receptor, triggering the inflammatory response observed in hospitalized patients.

Australia’s Speedx Pty Ltd. is launching a new rapid polymerase chain reaction (qPCR) test for 14 different respiratory viruses in a single test that works on almost every commercial PCR platform in half the time and at a fraction of the cost of what its competitors charge.

In what represents its first patenting, Halifax, Nova Scotia-based Hollo Medical Inc. seeks protection for its product that is designed for inhaler users who are frustrated with cumbersome valved holding chambers and desire something more compact and portable.

Paragonix Technologies Inc. expanded access to its U.S. FDA-cleared Baroguard donor lung preservation system following a successful limited release with a handful of top transplant centers. In addition to critical temperature control, the new system provides active airway management to keep donor lungs in the best condition possible.

Chiesi Farmaceutici SpA presented data for novel lung-targeted muscarinic M3 receptor antagonists/β2-adrenoceptor agonists (MABAs) as candidates for the treatment of chronic obstructive pulmonary disease (COPD).

South Korean medical software firm Coreline Soft Co. Ltd. said it gained U.S. FDA 510(k) clearance for its artificial intelligence-based coronary artery calcification assessing solution, Aview CAC, while raising ₩18 billion (US$13.33 million) in a private placement.

Avicenna.AI SAS received clearance from the U.S. FDA for two of its artificial intelligence (AI)-based solutions, Cina-Ipe and Cina-Aspects, which provide for the detection of pulmonary embolism (PE) and the assessment of stroke severity in CT scans, respectively.

Deep learning algorithms have enabled the discovery of molecular structures of interest in biomedicine to design treatments against aggressive diseases such as idiopathic pulmonary fibrosis (IPF). Scientists at Insilico Medicine Inc. selected a target for IPF using artificial intelligence (AI), then designed an inhibitor to block it, and tested it in vitro, in vivo, and in clinical trials.
