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 ...

The complement system has more than 50 soluble and membrane-bound proteins. In innate and adaptive immunity, complement is essential for eliminating foreign pathogens and apoptotic cells. It is also ...

Complement proteins may be helpful when it comes to rallying clearance of hazardous debris from the brain, but scientists believe the immune activators can also inflict irreparable damage to neurons ...

In a recent study posted to the bioRxiv* preprint server, researchers investigated the expression of complement regulatory proteins (CRPs) in coronavirus disease 2019 (COVID-19) to identify potential ...
