The complement system, a pivotal element of antiviral immunity, is a cascade of proteins found in the bloodstream and at mucosal sites, such as the respiratory tract. Activated through three different ...

Faults in a certain part of the immune system might be at the root of some long covid cases, new research suggests. For many people, covid is an illness that blusters in and out of our lives as cases ...

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 ...

Undertaking a study of proteins found in the complement system, an important part of the immune system, of patients with long COVID, researchers have identified a blood protein ‘signature’ that may ...

C3 glomerulopathy (C3G) and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN) are two rare kidney diseases. They’re both driven by activity of the complement system, which is a ...

Researchers have 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 ...

Researchers aimed to track the clinical course and characterize the global and COVID-specific immunity in the blood of individuals with long COVID. Two recent studies have analyzed the blood of ...
