Research Abstract

IgA nephropathy(IgAN), the most common glomerulonephritis, is characterized by mesangial IgA1-containing immunodeposits. Aberrant IgA1 and anti-glycan IgG are produced by activation of TLR9 and several cytokines. Serum levels of aberrant IgA1, anti-glycan IgG, and IgG-IgA immune complexes may be useful biomarkers for judgment of indication of tonsillectomy and efficacy of therapy.
