In Vivo Allograft Exposure to Mitochondrial DAMPs Prior to Organ Procurement Increases Graft Rejection in Mice
L. Lin, J. Wang, L. Cendales, A. Kirk, T. Brennan.
Surgery, Duke University, Durham, NC.
Mitochondria released in the setting of tissue injury are a source of damage associated molecular patterns (DAMPs) that initiate innate immune responses. We hypothesized that…
