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 ...

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 ...

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 ...

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 ...

In a recent study published in The New England Journal of Medicine, researchers reviewed selected acute-phase proteins concerning their production, structure, and function. The advent of severe acute ...

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes ...

Among people with sickle cell disease—an inherited blood disorder—acute chest syndrome (ACS) is the leading cause of death. The condition is the result of red blood cells becoming stiff, sticky, and ...

We sometimes hear about the benefits of “boosting” our immune system, but what we really want to do is support our immune system on an ongoing basis. People often think of the immune system as ...

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 ...
