Abstract
Cardiovascular disease is a worldwide health problem and a leading cause of morbidity and mortality. Preclinical cardiovascular research using animals is needed to explore potential targets and therapeutic options. Compared with rodents, pigs have many advantages, with their anatomy, physiology, metabolism and immune system being more similar to humans. Here we present an overview of the available pig models for cardiovascular diseases, discuss their advantages over other models and propose the concept of standardized models to improve translation to the clinical setting and control research costs.

Comparative transcriptome analysis between long- and short-term survival after pig-to-monkey cardiac xenotransplantation reveals differential heart failure development.

[PMID: 37808548 PMCID: PMC10552608 DOI: 10.1080/19768354.2023.2265150] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 07/27/2023] [Indexed: 10/10/2023] Open
Abstract
Cardiac xenotransplantation is the potential treatment for end-stage heart failure, but the allogenic organ supply needs to catch up to clinical demand. Therefore, genetically-modified porcine heart xenotransplantation could be a potential alternative. So far, pig-to-monkey heart xenografts have been studied using multi-transgenic pigs, indicating various survival periods. However, functional mechanisms based on survival period-related gene expression are unclear. This study aimed to identify the differential mechanisms between pig-to-monkey post-xenotransplantation long- and short-term survivals. Heterotopic abdominal transplantation was performed using a donor CD46-expressing GTKO pig and a recipient cynomolgus monkey. RNA-seq was performed using samples from POD60 XH from monkey and NH from age-matched pigs, D35 and D95. Gene-annotated DEGs for POD60 XH were compared with those for POD9 XH (Park et al. 2021). DEGs were identified by comparing gene expression levels in POD60 XH versus either D35 or D95 NH. 1,804 and 1,655 DEGs were identified in POD60 XH versus D35 NH and POD60 XH versus D95 NH, respectively. Overlapped 1,148 DEGs were annotated and compared with 1,348 DEGs for POD9 XH. Transcriptomic features for heart failure and inhibition of T cell activation were observed in both long (POD60)- and short (POD9)-term survived monkeys. Only short-term survived monkey showed heart remodeling and regeneration features, while long-term survived monkey indicated multi-organ failure by neural and hormonal signaling as well as suppression of B cell activation. Our results reveal differential heart failure development and survival at the transcriptome level and suggest candidate genes for specific signals to control adverse cardiac xenotransplantation effects.

Abstract
Gene-edited pigs could eventually provide organs that are safely and effectively protected from the human immune response without exogenous immunosuppression. Genome editing technology has revolutionized heart xenotransplantation and made transplantation of bioengineered pig hearts into humans a possibility. This first clinical application resulted from a tremendous amount of research. Dramatic early attempts of clinical cardiac xenotransplantation during the last century paved the way to modern xenotransplantation using bioengineered pig hearts. It appears that such genome-edited hearts will be most suitable for neonates and infants because of their immature immune system. The bioengineered pig heart may also be used as a bridge to human heart transplantation, avoiding the risk of thromboembolic events of durable ventricular assist devises in these young children. It is also intriguing to think that bioengineered hearts using pigs as a host may result in a new source of donor hearts that would not evoke the human immune response and minimize, if not eliminate, the need for immunosuppression. It this issue of the Journal, a group of experts led by Dr Cooper, whose personal work spans over 50 years of heart transplantation research, outline the current state of the genome editing of bioengineered hearts and discuss the prospects of clinical application.

Abstract
For many patients with terminal/advanced cardiac failure, heart transplantation is the most effective, durable treatment option, and offers the best prospects for a high quality of life. The number of potentially life-saving donated human organs is far fewer than the population who could benefit from a new heart, resulting in increasing numbers of patients awaiting replacement of their failing heart, high waitlist mortality, and frequent reliance on interim mechanical support for many of those deemed among the best candidates but who are deteriorating as they wait. Currently, mechanical assist devices supporting left ventricular or biventricular heart function are the only alternative to heart transplant that is in clinical use. Unfortunately, the complication rate with mechanical assistance remains high despite advances in device design and patient selection and management, and the quality of life of the patients even with good outcomes is only moderately improved. Cardiac xenotransplantation from genetically multi-modified (GM) organ-source pigs is an emerging new option as demonstrated by the consistent long-term success of heterotopic (non-life-supporting) abdominal and life-supporting orthotopic porcine heart transplantation in baboons, and by a recent 'compassionate use' transplant of the heart from a GM pig with 10 modifications into a terminally ill patient who survived for 2 months. In this review, we discuss pig heart xenotransplantation as a concept, including pathobiological aspects related to immune rejection, coagulation dysregulation, and detrimental overgrowth of the heart, as well as GM strategies in pigs to prevent or minimize these problems. Additional topics discussed include relevant results of heterotopic and orthotopic heart transplantation experiments in the pig-to-baboon model, microbiological and virologic safety concepts, and efficacy requirements for initiating formal clinical trials. An adequate regulatory and ethical framework as well as stringent criteria for the selection of patients will be critical for the safe clinical development of cardiac xenotransplantation, which we expect will be clinically tested during the next few years.

Niemann H. Xenotransplantate vom Schwein – ist das Ende des Organmangels
in Sicht? TRANSFUSIONSMEDIZIN 2022. [DOI: 10.1055/a-1814-8440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022]
Abstract
ZusammenfassungUnter „Xenotransplantation“ wird die Übertragung von
funktionsfähigen Zellen, Geweben oder Organen zwischen verschiedenen
Spezies verstanden, insbesondere von Schweinen auf den Menschen. In den meisten
Industrieländern klafft eine große Lücke zwischen der
Anzahl geeigneter Spenderorgane und der Anzahl benötigter Transplantate.
Weltweit können nur etwa 10% des Organbedarfs durch Spenden
gedeckt werden. Eine erfolgreiche Xenotransplantation könnte diesen
Mangel mildern oder sogar weitgehend vermeiden. Das Schwein wird aus
verschiedenen Erwägungen heraus als am besten geeignete Spenderspezies
angesehen. Bei einer Übertragung porziner Organe auf Primaten treten
verschiedene immunologisch bedingte Abstoßungsreaktionen auf, die das
übertragene Organ innerhalb kurzer Zeit zerstören
können, wie die HAR (hyperakute Abstoßung), die AVR (akute
vaskuläre Abstoßung) und die spätere zelluläre
Abstoßung. Diese Abstoßungsreaktionen müssen durch
genetische Modifikationen im Schwein und eine geeignete immunsuppressive
Behandlung des Empfängers kontrolliert werden. Dazu müssen Tiere
mit mehrfachen genetischen Veränderungen produziert und im Hinblick auf
ihre Eignung für eine erfolgreiche Xenotransplantation geprüft
werden. Inzwischen können die HAR und auch die AVR durch Knockouts von
antigenen Oberflächenepitopen (z. B. αGal
[Galaktose-α1,3-Galaktose]) und transgene Expression humaner Gene mit
antiinflammatorischer, antiapoptotischer oder antikoagulativer Wirkung
zuverlässig kontrolliert werden. Nach orthotopen Transplantationen in
nicht humane Primaten konnten inzwischen mit Schweineherzen
Überlebensraten von bis zu 264 Tagen und mit porzinen Nieren von 435
Tagen erzielt werden. Eine Übertragung pathogener Erreger auf den
Empfänger kann bei Einhaltung einschlägiger
Hygienemaßnahmen ausgeschlossen werden. PERV (porzine endogene
Retroviren) können durch RNA-(Ribonukleinsäure-)Interferenz oder
Gen-Knockout ausgeschaltet werden. Sie stellen damit kein
Übertragungsrisiko für den Empfänger mehr dar. Anfang
2022 wurde in Baltimore (USA) ein Schweineherz mit 10 genetischen Modifikationen
auf einen Patienten mit schwerem Herzleiden übertragen, mit dem der
Empfänger 2 Monate offenbar ohne größere Probleme lebte.
Es wird erwartet, dass Xenotransplantate vom Schwein in absehbarer Zeit zur
klinischen Anwendungsreife kommen werden. Dazu werden klinische Versuche zur
systematischen Erfassung aller Auswirkungen solcher Transplantate auf den
Patienten sowie geeignete rechtliche und finanzielle Rahmenbedingungen
benötigt.
