The major negative regulator of the AP is the plasma protein complement factor H (FH). Abnormalities in FH result in uncontrolled activation of C3 through the AP and associate with susceptibility to both C3G and aHUS. Although previously developed FH\u2013deficient animal models have provided important insights into the mechanisms underlying susceptibility to these unique phenotypes, these models do not entirely reproduce the clinical observations. FH is predominantly synthesized in the liver. We generated mice with hepatocyte\u2013specific FH deficiency and showed that these animals have reduced plasma FH levels with secondary reduction in plasma C3. Unlike mice with complete FH deficiency, hepatocyte\u2013specific FH\u2013deficient animals developed neither plasma C5 depletion nor accumulation of C3 along the glomerular basement membrane. In contrast, subtotal FH deficiency associated with mesangial C3 accumulation consistent with C3G. Although there was no evidence of spontaneous thrombotic microangiopathy, the hepatocyte\u2013specific FH\u2013deficient animals developed severe C5\u2013dependent thrombotic microangiopathy after induction of complement activation within the kidney by accelerated serum nephrotoxic nephritis. Taken together, our data indicate that subtotal FH deficiency can give rise to either spontaneous C3G or aHUS after a complement-activating trigger within the kidney and that the latter is C5 dependent.<\/jats:p>","DOI":"10.1681\/asn.2015030295","type":"journal-article","created":{"date-parts":[[2015,9,15]],"date-time":"2015-09-15T22:10:12Z","timestamp":1442355012000},"page":"1334-1342","source":"Crossref","is-referenced-by-count":35,"title":["Partial Complement Factor H Deficiency Associates with C3 Glomerulopathy and Thrombotic Microangiopathy"],"prefix":"10.1681","volume":"27","author":[{"given":"Katherine A.","family":"Vernon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marieta M.","family":"Ruseva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
