Outline of Final Research Achievements |
We reveal that CFB p.S367R has gain-of-function effects in CFB from the finding including structure-function relationship of CFB p.S367R and elevated soluble C5b-9 levels which indicate continuous activity of the complement alternative pathway. This is the first report that demonstrates the involvement of CFB in the etiology of MPGN. However, culturing a large quantity of CFB p.S367R was unsuccessful. Evaluation of soluble C5b-9 levels in patients with thrombotic microangiopathy(TMA) revealed complement activations contribute not only in the etiology of atypical hemolytic uremic syndrome, but also in shiga toxin producing E.coli-associated HUS and secondary TMA.
