EAV is characterized by hematuria, low-grade albuminuria, and focal crescent formation. Six weeks after immunization, hematuria (A) was assessed by dipstick and albuminuria (B) by ELISA. (C) The percentage of glomeruli with crescents was quantified on Periodic acid Schiff sections. ^***P < .001 comparing proteinuria between EAV and control rats. No statistical comparison is possible in panels A and C because all values in the control group are zero.
