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 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 ...

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 ...

The immune system’s first encounter with a virus or vaccine establishes a “starting template” that shapes its response to new variants, a phenomenon often called immune imprinting. A new study shows ...

There are two types of complement 3 glomerulopathy: dense deposit disease (DDD) and C3 glomerulonephritis (C3GN). DDD often begins earlier in life and may progress more quickly. Both are linked to an ...
