MPO and ganglioneuroma: A subset of the 29 renal biopsies used to measure ecDNA labeled (n = 6, the biopsies with sample remaining) with an anti-human DNase I antibody demonstrated patients with MPO-ANCA GN patients had less DNase I expression within the tubulointerstitium and glomeruli when compared with those from control patients with MCD (n = 6) (Figure 1C).
