Novel Complement C5 Small-interfering RNA Lipid Nanoparticle Prolongs Graft Survival in a Hypersensitized Rat Kidney Transplant Model
Conclusions. C5 siRNA-LNP combined with immunosuppressants CsA and DSG downregulated C5 activity and significantly prolonged graft survival compared with control siRNA-LNP with CsA and DSG. Downregulation of C5 expression using C5 siRNA-LNP may be an effective therapeutic approach for AMR.

Review of Current Machine Perfusion Therapeutics for Organ Preservation
Because of the high demand of organs, the usage of marginal grafts has increased. These marginal organs have a higher risk of developing ischemia-reperfusion injury, which can lead to posttransplant complications. Ex situ machine perfusion (MP), compared with the traditional static cold storage, may better protect these organs from ischemia-reperfusion injury. In addition, MP can also act as a platform for dynamic administration of pharmacological agents or gene therapy to further improve transplant outcomes. Numerous therapeutic agents have been studied under both hypothermic (1–8°C) and normothermic settings. Here, we...

Calcineurin Inhibitors Downregulate HNF-1β and May Affect the Outcome of HNF1B Patients After Renal Transplantation
Conclusions: Because HNF1B-related disease is a heterozygous condition, CNIs used to prevent rejection may induce reduced expression of the nonmutated allele of HNF1B leading to a superimposed defect of HNF-1β transcriptional activity. Taking into account the specific risk of posttransplantation diabetes mellitus and liver disorders in HNF1B patients, these findings advocate for in-depth characterization of pathways that regulate HNF1B and plead for considering individually tailored graft management that may include a CNI-free immunosuppressive regimen. Interventional studies will have to confirm this individualized approach.

Attenuating Ischemia-Reperfusion Injury in Kidney Transplantation by Perfusing Donor Organs With siRNA Cocktail Solution
Conclusions: In conclusion, this is the first demonstration that perfusing donor organs with an siRNA cocktail solution can induce gene silencing in the kidney and prevent kidneys from extended cold I/R injury in kidney transplantation, highlighting the promise of the clinical application of siRNA-based therapies in the preservation of donor organs.
