NewsSARS-CoV-2 ‘steals’ our proteins to protect itself from the immune system
Researchers at the Medical University of Vienna and the Medical University of Innsbruck discovered that SARS-CoV-2 hijacks three important host proteins that dampen the activity of the complement system, a key component of early antiviral immunity. This significantly impairs viral clearance which may affect the course of ...

NewsScientists assess efficacy of clinical drugs targeting SARS-CoV-2 main protease
A critical player in the virus’s life cycle is the main protease (Mpro), also known as NSP5 or 3CL protease, which plays a crucial role in the cleavage and maturation of SARS-CoV-2 proteins within the host cells.
