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.
