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 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 ...

Researchers have identified mutations in a set of proteins that predispose their carriers to preeclampsia, a complication that shows up in between 5 percent and 10 percent of pregnancies. Their work ...

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.

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 ...

Most people infected with the SARS-CoV-2 virus recover after the acute illness. However, a significant proportion of infected individuals develop long-lasting symptoms with a wide range of ...

Figure 1: Mannose-binding lectin (blue strands) can bind to sites on the SARS-Cov-2 spike protein on the cell membrane. One of the most striking features of the SARS-CoV-2 pandemic is that across all ...

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 ...
