Xenotransplantation White Papers in Transplantation

International Xenotransplantation Association (IXA) Position Paper on the History, Current Status, and Regulation of Xenotransplantation

Hawthorne, Wayne et al.
Transplantation ():10.1097/TP.0000000000005373, April 08, 2025. | DOI: 10.1097/TP.0000000000005373

Landmark xenotransplants are the result of 30+ years of innovation—genetic, immunologic, ethical & regulatory. The IXA, TTS & WHO have laid the groundwork for safe clinical translation.

Key breakthroughs include:

Genetic modifications of source pigs
Novel immunosuppressive strategies
Technical innovations
Development of ethical & regulatory frameworks

Each was critical to safe clinical translation.

The International Human Xenotransplantation Inventory: Current Data and Future Directions

Hu, Xiaowei et al.
Transplantation ():10.1097/TP.0000000000005367, April 08, 2025. | DOI: 10.1097/TP.0000000000005367

Xenotransplantation is emerging as a solution to the global organ shortage. Since 2006, a WHO-endorsed registry has tracked 50+ clinical cases—paving the way for safer, transparent progress.

Over the past 2 decades, the registry reveals key trends:

Types of xenotransplants
Source animals (mostly pigs)
Regulatory status of procedures
Countries involved

Xenotransplantation in Humans: A Reality Check

Tector, A. Joseph
Transplantation 109(2):p 231-234, February 2025. | DOI: 10.1097/TP.0000000000005223

Thirty years after the initial strategies to develop genetically engineered pigs for use as organ donors in xenotransplantation were described, evaluation of these pig organs in humans has begun.

Path to clinical xenotransplantation. The development of a new pig with a better crossmatch in patients will require (A) additional genetic engineering followed by testing in a preclinical nonhuman primate model that will include identification of an immunosuppressive regimen that can be used in clinical trials (B). The development of more detailed histocompatibility testing will facilitate the identification of the most appropriate initial recipients to ensure clinical success (C).

Special Feature:

International Xenotransplantation Association (IXA) Position Paper on Infectious Disease Considerations in Xenotransplantation

Fishman, J. A., Denner, J., & Scobie, L. (2025).
Transplantation ():10.1097/TP.0000000000005371, April 08, 2025. | DOI: 10.1097/TP.0000000000005371

Transplantation Journal Highlights

Transplantation Journal - Social Media Content

The Use of Opioid Medications in Lung Transplant: A Scoping Review

Opioids are frequently used for dyspnea and analgesia in lung transplant patients; however, consensus is mixed regarding the impact of opioids on lung transplantation outcomes.

Chronic Rejection After Kidney Transplantation

In kidney transplantation, ongoing alloimmune processes—commonly triggered by HLA incompatibilities—can trigger chronic transplant rejection, affecting the microcirculation and the tubulointerstitium. Continuous inflammation may lead to progressive, irreversible graft injury, culminating in graft dysfunction and accelerated transplant failure.

Transplantation Direct - Social Media Content

Exploring Caregiver Support as a Potential Mediator of Neighborhood Socioeconomic Disadvantage and Reduced Likelihood of Liver Transplant Waitlisting

Individuals from socioeconomically disadvantaged neighborhoods may be at risk of inequitable access to the liver transplant (LT) waitlisting (WL), but mechanisms mediating this relationship are not well understood. We assessed whether area deprivation index (ADI), a measure of neighborhood socioeconomic deprivation, was associated with LT WL and assessed whether caregiver support, a potentially modifiable factor, mediated this relationship.

2025 Medical Directors Forum

This interactive forum will provide networking and collaboration opportunities that will enhance your daily practice as a transplant leader.

Target Audience:
Medical Directors or an appropriate proxy with a leadership role from each organ transplant program. International medical directors are welcome to attend. New this year: living donor medical directors are also invited to attend.

This exclusive two-day meeting will be held immediately prior to the World Transplant Congress, from August 1-2, 2025, in San Francisco, CA.

Application notifications will be sent based on verification of Medical Director's status. For more information and to register, visit the AST website. If you have any questions, please email astmeetings@myast.org

Research Grants and Fellowship Programs

TTS provides funding to individual investigators to support their research in transplantation. The spectrum of studies includes basic, clinical/epidemiological and translational. This individual should have spent five years or less performing research in transplantation (and/or immunology relating to transplant) since obtaining their last doctoral degree (PhD, MD, PharmD, or equivalent). One of these research grants will be preferentially designated to TTS members from a low- or middle-income country. Please send application materials and any questions to jennifer.groverman@tts.org.

Letter of Intent Deadline: April 30, 2025

The ISN and TTS join forces to support the training of young physicians from low resource areas receiving hands-on training in advanced host institutions to acquire state of-the-art knowledge in transplantation. The ultimate goal of such training is to improve the transplantation standards in their home countries upon their return and become leaders in their fields. The training focuses on providing the skills and knowledge specifically required by the home institution. ISN-TTS Fellowship trainings can be long (6-12 months) or short term (3-6 months).

Application Deadline: May 1, 2025

This grant will provide funding of up to $20,000 USD per grant to support research focused on sex and gender equity, advocacy, and health in solid organ transplantation amongst Indigenous peoples globally. This may include basic, clinical, or translational research. The recipient must be a clinician, health policy administrator, social scientist, clinical and/or basic science researcher in solid organ transplantation or donation, and/or Indigenous health relating to solid organ transplant.

Application Deadline: May 1, 2025
