Abstract

The unpredictable progression of IgA nephropathy hinders its treatment. The correlation of renal dysfunction with the immunophenotype of leukocytic infiltrates revealed interstitial CD20(+) cells and tubular NKG7(+)(GMP-17(+))/CD8(+) intraepithelial cells as predictive markers of progression in early-phase IgA nephropathy. This suggests that adaptive and innate immune responses mediate progression.
