Innate immunity is a foundational field in immunology, critical for understanding how organisms sense and respond to danger, be it pathogens or sterile ...

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 ...

The complement component C5a and its receptors, C5aR1 and C5aR2, are central to the orchestration of innate immunity. C5a is a potent anaphylatoxin generated during complement activation, acting as a ...

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 ...

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 ...

A study led by researchers at Queen Mary University of London has found that hormone replacement therapy (HRT) may help reverse changes in the immune system caused by menopause, potentially boosting ...

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 ...
