Fig. 1.
One-year-old ERα-/- mice develop autoimmune glomerulonephritis. Kidney sections from 1-year-old ERα-/- (B) and ERαβ-/- (D) mice stained with hematoxylin/eosin show glomerulonephritis, but WT (A) and ERβ-/- (C) mice do not. Deposition of IgG was detected by immunofluorescence with kidney sections from WT (E and F) and ERα-/- (G and H) mice. IgG deposition in the kidney is shown in ERα-/- (G) but not WT (E) mice. Counterstained nuclei with DAPI are shown in F and H. Fifteen ERα-/- and 15 WT animals were evaluated.
