The complement system is a key component of innate and adaptive immunity and therefore acts as a vital defense against invading pathogens. Deficiencies in the complement system are associated with ...

Our immune system is armed with an array of defenses designed to detect and eliminate harmful threats. One of its most powerful defense mechanisms is the complement system-a group of proteins that ...

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 ...

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 ...

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 ...

An MUSC research team reports in Cells that the complement system, part of the body’s natural immune defenses, is a key driver of inflammatory responses that contribute to fetal brain inflammation and ...

Innate Immunity is a nonspecific host defense mechanism against foreign antigens. It is the first line of defense in a host and occurs immediately or within hours after exposure. This type of immunity ...

Long Covid patients suffer from chronic symptoms such as fatigue or shortness of breath. As researchers have discovered, this is to some extent due to a part of our immune system called the complement ...

Changes to serum proteins could be behind the debilitating condition known as long COVID. The findings, published in the journal Science, could pave the way for diagnosing and treating the disease.
