Gasdermin-D Mutation is Protective against Renal Ischemia Reperfusion Injury
J. Li, N. Rogers, S. Alexander
Centre for Transplant and Renal Research, Westmead Institute for Medical Research, Westmead, Australia
*Purpose: Pyroptosis, a pro-inflammatory form of cell death, is dependent on membrane pore formation through the assembly of cleaved Gasdermin-D molecules. We hypothesized that this…

Ex Vivo Isolated Human Vessel Perfusion System for the Design and Assessment of Nanomedicines Targeted to the Endothelium
L. G. Bracaglia¹, T. Lysyy², L. Qin², C. Albert¹, J. S. Pober², G. Tellides², W. M. Saltzman¹, G. T. Tietjen²
¹Yale University, New Haven, CT, ²Yale School of Medicine, New Haven, CT
*Purpose: In solid organ transplantation the host immune system acts to reject the graft. This process is facilitated at the endothelial surface, where inflamed donor…

IL-10 Signaling in T Cells is Essential for Induction of Transplant Tolerance
M. Iglesias Lozano, D. Bibicheff, M. Chicco, G. Brandacher, G. Raimondi
Plastic Surgery, Johns Hopkins University, Baltimore, MD
*Purpose: Induction of long term transplant survival by “costimulation blockade” (CoB) is achieved through deletion of abortively activated alloreactive T cells and generation of graft…
