The Role of TNF Superfamily Member 13 in the Progression of IgA Nephropathy.

ABSTRACT: TNF superfamily member 13 (TNFSF13) has been identified as a susceptibility gene for IgA nephropathy in recent genetic studies. However, the role of TNFSF13 in the progression of IgA nephropathy remains unresolved. We evaluated two genetic polymorphisms (rs11552708 and rs3803800) and plasma levels of TNFSF13 in 637 patients with IgA nephropathy, and determined the risk of ESRD according to theses variable. Neither of the examined genetic polymorphisms associated with a clinical outcome of IgA nephropathy. However, high plasma levels of TNFSF13 increased the risk of ESRD. To explore the causal relationship and underlying mechanism, we treated B cells from patients (n=21) with or without recombinant human TNFSF13 (rhTNFSF13) and measured the expression of IgA and galactose-deficient IgA (GdI
