Proteinuria affects most people with complement 3 glomerulopathy (C3G). Protein in urine is one of the strongest indicators of disease progression. Reducing proteinuria can slow the progression of C3G ...

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 ...

C3 glomerulopathy (C3G) and immune complex membranoproliferative glomerulonephritis (IC-MPGN) are rare kidney conditions caused by an overactive complement system, part of the immune system. C3G ...

(Left) Pre-ignition (below the activation threshold) Only a handful of immune “tags” (C3b proteins) cover the nanoparticle, so it barely sticks to the white membrane—too few contact points means the ...

Hereditary angioedema (HAE) is diagnosed through blood tests that measure complement protein (C4) and complement inhibitor (C1-INH) levels. Low C4 levels strongly suggest HAE, especially during an ...

Our immune system works around the clock to protect us from bacteria, viruses, and other harmful germs. It also helps repair damaged tissues after injuries. One of its most important defense tools is ...
