Peptidylarginine deiminase 4 (PAD4) inhibitor decreased neutrophil extracellular traps (NETs) at 24 h after renal ischemia reperfusion injury (I/R) and attenuated lupus characteristics (anti-dsDNA, glomerular immunoglobulin deposition and lupus nephritis) at 120 h post-I/R in lupus prone mice. Characteristics of Fcgr2b-/- mice after renal I/R with PAD4 inhibitor or phosphate buffer solution (PBS) as determined by indicators of NETs in serum; serum dsDNA and serum myeloperoxidase (MPO) (A, B), NETs in kidneys; co-staining of MPO and neutrophil elastase (NE) with the representative pictures (C, D) and characteristics of lupus nephritis; serum dsDNA, proteinuria (urine protein creatinine index; UPCI), and serum creatinine (E–G) are demonstrated (n = 4–5/group).
