Caroline Lamarche, Megan K Levings
PURPOSE OF REVIEW: The application of regulatory T cell (Treg) therapy in organ transplantation is actively being pursued using unmodified, typically polyclonal cells. As the results of these ongoing clinical trials emerge, it is time to plan the next wave of clinical trials of Tregs. Here we will review a key strategy to improve Treg effectiveness and reduce side effects, namely increasing Treg specificity - both in terms of antigen recognition and localization to the allograft. RECENT FINDINGS: Study of chemokine signatures accompanying acute rejection has revealed several chemokines that could be targeted to increase Treg homing...

Silvia Minardi, Sahil Shah, Xunrong Luo
PURPOSE OF REVIEW: The current review aims to provide a current landscape and future trends of biomimetic nanoparticles which have the potential to revolutionize the field of transplantation in the next decade. RECENT FINDINGS: Currently, the inability to safely induce robust donor-specific immunological tolerance makes it difficult to achieve immunosuppression-free graft survival. Despite progresses in the development of nanotherapeutics for antigen-specific immunomodulation in autoimmune diseases and in cancer treatments, few have been proposed and tested in transplantation with success...

Nathan W Zammit, Shane T Grey
PURPOSE OF REVIEW: Clinical islet transplantation does not enjoy the success seen for solid organ transplants, indicating a need for new therapeutic approaches to improve patient outcomes. This has prompted investigation into islet autonomous factors and pathways that may represent druggable targets. These have the potential to synergize with approaches aimed at generating graft-specific tolerance. RECENT FINDINGS: There are emerging data that nuclear factor κB (NF-κB) activation can prevent and or overcome tolerance, whereas dampening NF-κB activation in immune cells is associated with prolonged allograft survival...

PURPOSE OF REVIEW: Donation after circulatory death (DCD) is still performed in a limited number of countries. This article summarizes the development of DCD in Spain and presents recent Spanish contributions to gain knowledge on the potential benefits and the practical use of normothermic regional perfusion (nRP). RECENT FINDINGS: DCD now contributes to 24% of deceased donors in Spain. The development of DCD has been based on an assessment of practices in the treatment of cardiac arrest and end-of-life care to accommodate the option of DCD; the creation of an adequate regulatory framework; and institutional support, professional training and public education...

PURPOSE OF REVIEW: Purine nucleosides and nucleotides are released in the extracellular space following cell injury and act as paracrine mediators through a number of dedicated membrane receptors. In particular, extracellular ATP (eATP) significantly influences T-lymphocyte activation and phenotype. The purpose of this review is to discuss the role of ATP signaling in the T-cell-mediated alloimmune response. RECENT FINDINGS: In various animal models of solid transplantation, the purinergic axis has been targeted to prevent acute rejection and to promote long-term graft tolerance...

James T Harden, Sheri M Krams
PURPOSE OF REVIEW: Micro-RNAs (miRNAs) are highly conserved small RNA molecules that have selective gene-regulatory functions. This posttranscriptional regulation by miRNAs is critical for many immunological processes. Many developments in establishing the biological role of miRNAs in solid organ transplantation have been generated in the last decade. Discoveries of immune regulation by miRNAs, resulting in graft prolongation and transplant tolerance, are rapidly advancing and are the subject of this review...

Andrew McGee, Dale Gardiner, Paul Murphy
PURPOSE OF REVIEW: The recently developed donation after circulatory death (DCD) heart transplant technique, pioneered by Papworth Hospital in the UK, involves the use of extracorporeal perfusion technologies to restart the donor heart in situ and thereby restore the donor's own circulation, after first isolating the donor's cerebral circulation. By restoring the circulation in the deceased donor, even if the cerebral circulation is excluded, the Papworth technique challenges the acceptability of death determination in DCD...

PURPOSE OF REVIEW: The increasing reliance on marginal donors has driven research to investigate ways to repair and improve the quality of kidneys for transplantation. Normothermic perfusion technologies provide an opportunity for improved preservation, organ assessment and resuscitation/repair of damaged kidneys. This review describes the evolution of normothermic perfusion in kidney transplantation in the United Kingdom. RECENT FINDINGS: One hour of normothermic perfusion can be used to restore function and improve early graft function of extended criteria donor kidneys...

PURPOSE OF REVIEW: Cardiac xenotransplantation has entered an exciting era, marked by numerous considerable advances in the field, and continues to be of great interest because of its potential ability in ameliorating the current constraints of limited allograft availability. This review aims to examine recent progress in this rapidly changing discipline. RECENT FINDINGS: Although several hurdles remain, the use of rapidly evolving transgenic technology, in combination with novel immunosuppression regimens, has the potential to address current allogenic donor pool constraints and mechanical circulatory system device limitations...

Kazuhiko Yamada, Megan Sykes, David H Sachs
PURPOSE OF REVIEW: This review describes recent progress in tolerance-inducing strategies across xenogeneic immunological barriers as well as the potential benefit of a tolerance strategy for islets and kidney xenotransplantation. RECENT FINDINGS: Using advanced gene editing technologies, xenotransplantation from multitransgenic alpha-1,3-galactosyltransferase knockout pigs has demonstrated marked prolongation of renal xenograft survival, ranging from days to greater than several months for life-supporting kidneys, and more than 2 years in a heterotopic nonlife-supporting cardiac xenograft model...

Terry D Schneekloth, Shehzad K Niazi, Douglas A Simonetto
PURPOSE OF REVIEW: The majority of liver transplantation centers have required patients with alcohol-induced liver disease to demonstrate a period of abstinence (generally 6 months' duration) to qualify for transplant listing. This requirement has excluded patients with alcoholic hepatitis from transplant consideration. Since 2011, several studies have examined the outcomes of patients undergoing liver transplantation with brief abstinence as a lifesaving intervention for alcoholic hepatitis...

Andrea Schlegel, Xavier Muller, Philipp Dutkowski
PURPOSE OF REVIEW: The review describes recent developments in hypothermic machine liver perfusion with a special focus on underlying protective mechanisms, and the role of this perfusion technique in high-risk donor-recipient combinations. RECENT FINDINGS: To maximize the number of transplantable donor livers, several centres are exploring new machine preservation techniques. In this context, hypothermic machine perfusion has been recently introduced into the clinical setting of human liver transplantation, and the effect of endischemic cold liver perfusion on posttransplant complications is currently under investigation in two multicentre, randomized controlled trials...

Dagmar Kollmann, Markus Selzner
PURPOSE OF REVIEW: Organ shortage remains a major obstacle for liver transplantation, resulting in an increased mortality on the liver transplant waiting list. The usage of extended criteria donors (ECD) is a strategy to increase the number of available donor organs, however, with the risk of a higher rate of posttransplant graft dysfunction. Novel preservation strategies, such as warm ex-vivo liver perfusion, could improve the outcome of liver transplantation with ECD grafts. The present review summarizes the advances in the field of warm ex-vivo liver perfusion over the last 12 months...

Shehzad Niazi, Terry Schneekloth, C Burcin Taner
PURPOSE OF REVIEW: With expanding experience and success of liver transplantation, increasing numbers of elderly candidates await and undergo liver transplantation. There is accumulating evidence that graft survival and mortality does not appear to differ significantly between the young and carefully selected elderly liver transplantation recipients. Although existing evidence suggests that psychosocial factors impact outcomes after liver transplantation in general, no such information is available specifically for elderly (age ≥65 years) liver transplantation recipients...

Annemarie Weissenbacher, James Hunter
PURPOSE OF REVIEW: Normothermic machine perfusion (NMP) is a preservation method that is generating increasing interest. The aim of this review is to summarise the current status of NMP in regards of kidney viability assessment, reducing organ damage and improving transplant logistics. RECENT FINDINGS: The results of recent large animal experiments and clinical trials show that continuous prolonged normothermic ex-vivo kidney perfusion appears better than a brief period of NMP after static cold storage in terms of renal injury and function...

Burcin Ekser, Ping Li, David K C Cooper
PURPOSE OF REVIEW: To review the progress in the field of xenotransplantation with special attention to most recent encouraging findings which will eventually bring xenotransplantation to the clinic in the near future. RECENT FINDINGS: Starting from early 2000, with the introduction of galactose-α1,3-galactose (Gal)-knockout pigs, prolonged survival especially in heart and kidney xenotransplantation was recorded. However, remaining antibody barriers to non-Gal antigens continue to be the hurdle to overcome...
