Enhancement of renal disease in MPO\u2010deficient mice correlated with increased accumulation of CD4+ T cells and macrophages in glomeruli, which, in turn, was associated with augmented generation of CD4+ T cell responses and increased activation and migration of dendritic cells in secondary lymphoid organs. In addition, the enhanced renal injury in MPO<jats:sup>\u2013\/\u2013<\/jats:sup> mice was associated with increased glomerular accumulation of neutrophils and deposition of neutrophil extracellular traps.
