PARP1 inactivation reduces macrophage influx during the period of kidney interstitial fibrosis after IRI. a Macrophages were detected by immunohistochemistry using anti-F4/80 antibody in kidney sections at 16 days after IRI. Scale bars indicate 50 μm. b Percentage of F4/80-positive area in the kidney sections. Error bars represent SD (n = 5). # P < 0.05 versus vehicle
