Progress and challenges in lung xenotransplantation: an update.[Pubmed:30234737]
Curr Opin Organ Transplant. 2018 Dec;23(6):621-627.
PURPOSE OF REVIEW: Recent progress in genetic engineering has facilitated development of transgenic donor animals designed to overcome the known barriers to discordant xenotransplantation, and greatly accelerated progress in the field of xenotransplantation. Here we review and summarize recent progress in lung xenotransplantation, and discuss possible additional genetic modifications and other interventions that may further advance the use of pulmonary xenografts towards clinical applications based on known mechanisms of xeno lung injury. RECENT FINDINGS: Ex-vivo lung perfusion experiments have shown that the addition of human complement (hCD46, hCD55), coagulation (hEPCR, hVWF, hTBM, hTFPI, hCD39), or anti-inflammatory pathway regulatory genes (HO-1, HLA-E), and the knockout (KO) of major porcine carbohydrates (GalT, Neu5Gc, B4Gal) have each protective effects on lung survival and function. The use of these transgenes in multitransgenic donor organs, targeting several known xenogeneic rejection mechanisms, combined with drug treatments addressing remaining known rejection pathways, have led to prolonged recipient survival of up to 31 days with in some cases preserved live-supporting organ function of the transplanted graft for several days. Pulmonary vascular resistance elevation, which has been found to be associated with high thromboxane levels and has been the major failure reason of xenogeneic lung grafts in the past years, has been successfully attenuated by the addition of a thromboxane synthase inhibitor (1-Benzylimidazole). Currently, the predominant failure mechanism of xenogeneic lung grafts is an inflammatory process, leading to vascular barrier function injury with interstitial and trachea edema. Work with other pig organs in primate models show that regimens based on costimulatory pathway blocking antibodies prolong xenograft function for months to years, suggesting that once initial lung inflammation mechanisms are fully controlled, clinically useful application of pig lung xenografts may be feasible. SUMMARY: The use of multitransgenic donor pigs coupled with drugs targeting complement activation, coagulation, and inflammation have significantly improved the survival of xenogeneic pig lungs both during ex vivo human blood perfusion and in life-supporting in vivo models, and for the first time allowed consistent life-supporting function of lung xenografts. Overcoming delayed loss of vascular barrier function injury appears to be within reach, and will be essential to make lung xenografts a clinically relevant treatment option.
Thromboxane and histamine mediate PVR elevation during xenogeneic pig lung perfusion with human blood.[Pubmed:30175863]
Xenotransplantation. 2018 Sep 3:e12458.
BACKGROUND: Elevated pulmonary vascular resistance (PVR), platelet adhesion, coagulation activation, and inflammation are prominent features of xenolung rejection. Here, we evaluate the role of thromboxane and histamine on PVR, and their contribution to other lung xenograft injury mechanisms. METHODS: GalTKO.hCD46 single pig lungs were perfused ex vivo with fresh heparinized human blood: lungs were either treated with 1-Benzylimidazole (1-BIA) combined with histamine receptor blocker famotidine (n = 4) or diphenhydramine (n = 6), 1-BIA alone (n = 6) or were left untreated (n = 9). RESULTS: Six of the nine control experiments (GalTKO.hCD46 untreated), "survived" until elective termination at 4 hours. Without treatment, initial PVR elevation within the first 30 minutes resolved partially over the following hour, and increased progressively during the final 2 hours of perfusion. In contrast, 1-BIA, alone or in addition to either antihistamine treatment, was associated with low stable PVR. Combined treatments significantly lowered the airway pressure when compared to untreated reference. Although platelet and neutrophil sequestration and coagulation cascade activation were not consistently altered by any intervention, increased terminal wet/dry weight ratio in untreated lungs was significantly blunted by combined treatments. CONCLUSION: Combined thromboxane and histamine pathway blockade prevents PVR elevation and significantly inhibits loss of vascular barrier function when GalTKO.hCD46 lungs are perfused with human blood. Platelet activation and platelet and neutrophil sequestration persist in all groups despite efficient complement regulation, and appear to occur independent of thromboxane and histamine antagonism. Our work identifies thromboxane and histamine as key mediators of xenolung injury and defines those pathways as therapeutic targets to achieve successful xenolung transplantation.
