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 ...

C3G and IC-MPGN both cause protein deposits that reduce kidney function. Overactive proteins in the immune system lead to these different conditions. C3G and IC-MPGN are rare kidney conditions. They ...

Complement 3 glomerulopathy (C3G) is a rare kidney disease that affects your body’s innate immune system (complement system). Complement 3 glomerulopathy (C3G) is a kidney disease that’s caused by ...

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 ...

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 ...
