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 ...

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

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 ...

Long Covid has long eluded scientists looking for its cause. Not knowing what triggers its persistent and distressing symptoms makes the condition challenging to treat; it’s hard to even say ...

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 ...

Chennai: People whose immune systems mount an unusually aggressive early response to tuberculosis may be less likely to respond well to standard drug .

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 ...

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 ...
