Another key event for virus entrance into the host is represented by the cellular transmembrane protease serine 2 (TMPRSS2) that drives the spoke protein priming (Hoffmann et al., 2020). 19. In agreement with these findings, directed expression of human and bat (Rhinolophus alcyone) ACE2 but not human DPP4, the entry receptor used by MERS-CoV (Raj et al., 2013), or human APN, the entry receptor used by … SARS-CoV-2 cell entry depends on ACE2 and TMPRSS2 and is blocked by a clinically proven protease inhibitor. DOI: 10.1016/j.cell.2020.02.016 Abstract Using untargeted metabolomics (n = 1,162 subjects), the plasma metabolite (m/z = 265.1188) phenylacetylglutamine (PAGln) was discovered and then shown in an independent cohort (n = 4,000 subjects) to be associated with cardiovascular disease (CVD) and incident major adverse cardiovascular events (myocardial infarction, stroke, or death). Hoffmann M, Kleine-Weber H, Schroeder S, et al. Daly et al. There is no existing treatment specific for COVID-19. Antiviral therapy is urgently needed to combat the coronavirus disease 2019 (COVID-19) pandemic, which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Background The ongoing outbreak of the recently emerged novel coronavirus (2019-nCoV) poses a challenge for public health laboratories as virus isolates are unavailable while there is growing evidence that the outbreak is more widespread than initially thought, and international spread through travellers does already occur. Development of effective prevention and treatment is an urgent need, especially for the life-threatening severe cases. Epub 2020 May 5.
