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 ...

C3 glomerulopathy (C3G) and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN) are two rare kidney diseases. They’re both driven by activity of the complement system, which is a ...

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.

The results of a newly reported study may offer scientists a strategy for mitigating the negative side effects associated with intravenous injection of nanoparticles used in medicine. The new approach ...

Complement 3 glomerulopathy (C3 glomerulopathy) is a very rare kidney disease. Those diagnosed with it have one of two forms of this disease: dense deposit disease (DDD) or C3 glomerulonephritis (C3GN ...
