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 ...

These findings suggest complement protein levels may be an important biomarker for type 1 diabetes. Disruption of the complement system appears to precede the onset of islet autoimmunity (IA), making ...

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 ...

A complement C4 (also known as a complement component 4, or simply C4) is a test to measure the level of C4 proteins you have in your blood. These proteins play a role in how your immune system ...

Current treatment methods for C3 glomerulopathy (C3G) help support kidney function and suppress immune system activity. Emerging therapies interrupt the proteins responsible for disease activity. C3G ...
