CD4 and IgA glomerulonephritis: Furthermore, CD122 expression on CD4+ T cells and CD25+ CD4+ T cells and CD25neg CD4+ T cells was not different between HC and patients with IgA-nephropathy (CD4+ T cells: %CD122+47 ± 13% versus 44 ± 11%, ns; CD4+CD25+: 62 ± 9% versus 56 ± 9%, ns; CD4+CD25neg: 44 ± 14% versus 41 ± 10%, ns).
