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.

Delivering siRNA Compounds During HOPE to Modulate Organ Function: A Proof-of-concept Study in a Rat Liver Transplant Model
Conclusions. FAS inhibition through siRNA therapy decreases the severity of IRI after LT in a SCS protocol; however the association of siRNA therapy with a HOPE perfusion model is very challenging. Future studies using better designed siRNA compounds and appropriate doses are required to prove the siRNA therapy effectiveness during liver HOPE liver perfusion.

Yikang decoction facilitates embryo implantation in mice with implantation dysfunction via upregulation of LIF expression
CONCLUSION: Yikang decoction can regulate the expression of αvβ3 and increase cell adhesion by upregulating the expression of LIF, thereby improving embryo implantation in mice. These data suggest that Yikang decoction may have therapeutic effect in treating infertility.PMID:35810979 | DOI:10.1016/j.trim.2022.101662

Klotho Regulates Epithelial-to-Mesenchymal Transition In Vitro via Wnt/ β-Catenin Pathway and Attenuates Chronic Allograft Dysfunction in a Rat Renal Transplant Model
CONCLUSIONS Our results show that Klotho has a significant protective role against EMT, renal allograft fibrosis, and CAD following kidney transplantation, which is mediated by inhibition of the Wnt/ß-catenin signaling pathway.PMID:33737505 | DOI:10.12659/AOT.930066

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...

The role of machine perfusion in liver xenotransplantation.
Abstract PURPOSE OF REVIEW: To review the role of machine perfusion in advancing the study and clinical application of liver xenotransplantation to liver transplantation. RECENT FINDINGS: Recent multicenter trial has shown the benefits of normothermic machine perfusion (NMP) in the assessment and selection of suitable allografts for liver transplantation, especially marginal liver allografts. Advances in ex-vivo therapeutic intervention with proof-of-concept studies demonstrating successful ex-vivo genetic modification of donor allografts and blockade of gene expression with siRNA. SUMMARY: Xenotransplan...

Sirtuin 1 Attenuates Inflammation and Hepatocellular Damage in Liver Transplant Ischemia ‐Reperfusion: From Mouse‐to‐Human
In conclusion, our translational study is the first to identify SIRT1 as a regulator of hepatocellular function in human liver transplant recipients under IR‐stress. By targeting innate and adaptive immune activation, manipulation of SIRT1 signaling should be considered as novel means to combat inflammation in liver transplantation.

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.
