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 ...

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 ...

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 ...

A collaborative team from the School of Engineering and Applied Science and the Perelman School of Medicine have unraveled the mathematics of a 500-million-year-old protein network that acts like the ...
