Linked sensitization by memory CD4+ T cells prevents costimulation blockade–induced transplantation tolerance

open access: yesJCI Insight, 2022
Dominant infectious tolerance explains how brief tolerance-inducing therapies result in lifelong tolerance to donor antigens and “linked” third-party antigens, while recipient sensitization and ensuing immunological memory prevent the successful ...

The changing immunology of organ transplantation [PDF]

open access: yes, 1995
The engrafted organ becomes a chimera as the recipient's leukocytes station themselves in the transplant. Remarkably, the recipient becomes chimeric as well, in a reverse migration involving immune cells from the graft.

Overexpression of PD-1 on T cells promotes tolerance in cardiac transplantation via ICOS-dependent mechanisms

open access: yesJCI Insight, 2021
The programmed death 1/programmed death ligand 1 (PD-1/PD-L1) pathway is a potent inhibitory pathway involved in immune regulation and is a potential therapeutic target in transplantation. In this study, we show that overexpression of PD-1 on T cells (PD-

Chimerism after organ transplantation [PDF]

open access: yes, 1997
Recent evidence suggests that passenger leukocytes migrate after organ transplantation and produce persistent chimerism, which is essential for sustained survival of the allograft.

Immunology of skin transplantation

open access: yesClinics in Dermatology, 2005
Untreated viable allogeneic skin is highly immunogenic. Epidermal Langerhans migrate after transplantation out of the donor skin into the lymph node of the recipient where they can activate T cells capable to mediate rejection. Allogeneic skin is used as a temporary coverage of burn wounds, often in combination with autologous skin grafts.

Microchimerism, dendritic cell progenitors and transplantation tolerance [PDF]

open access: yes, 1995
The recent discovery of multilineage donor leukocyte microchimerism in allograft recipients up to three decades after organ transplantation implies the migration and survival of donor stem cells within the host.

On the crossroad between tolerance and posttransplant lymphoma. [PDF]

open access: yes, 1997
The role of the Epstein-Barr virus in the development of post-transplant lymphomas is well established. However, not all lymphomas that arise in these patients contain Epstein-Barr virus, suggesting that other cofactors are involved in tumor pathogenesis.

IMMUNOLOGICAL MONITORING IN TRANSPLANTATION [PDF]

open access: yesMedical Journal Armed Forces India, 1997
Sixty eight patients who had undergone live related donor renal transplantation (LRD), were evaluated for soluble interleukin-2 receptors (sIL-2R), tumour necrosis factor alpha (TNF-α) and autoantibodies against IgG(Fab')2 and IgG(Fc), at pre- and various post-transplant intervals.

Transplantation tolerance from a historical perspective [PDF]

open access: yes, 2001
Although transplantation immunology as a distinctive field began with the development of experimental models that showed the feasibility of bone marrow transplantation, organ engraftment was accomplished first in humans, and was thought for many years to

Single cell transcriptomics of mouse kidney transplants reveals a myeloid cell pathway for transplant rejection

open access: yesJCI Insight, 2020
Myeloid cells are increasingly recognized as major players in transplant rejection. Here, we used a murine kidney transplantation model and single cell transcriptomics to dissect the contribution of myeloid cell subsets and their potential signaling ...
