Cell-Free Dna Release During Programmed Cell Death In Kidney Ischemia Reperfusion Injury, Alexander Dionne

Electronic Thesis and Dissertation Repository

Transplantation is invariably associated with ischemia reperfusion injury (IRI) which causes organ dysfunction. IRI is also directly linked to several forms of programmed cell death including apoptosis and necroptosis, which increase kidney dysfunction, promote inflammation and may contribute to premature graft failure. The contribution of necroptosis and apoptosis following kidney IRI to cell-free DNA (cfDNA) generation and the potential of cfDNA to activate effectors such as NK cells involved in kidney IRI have not been defined. Our data indicate that necroptotic microvascular endothelial cells (MVECs) release considerably more cfDNA than apoptotic MVECs or untreated controls (p
