Graft rejection – endogenous or allogeneic?

open access: yesImmunology, 2012
SummaryThe presence and persistence of alloantigen is necessary for graft‐specific T‐cell‐mediated immunity. However, specificity comprises only a single facet of an extremely complex process. Evidence is accruing to suggest that immunogenicity could be manipulated by endogenous ligands released during tissue injury.

Approaches toward enhancing survival probability following deep anterior lamellar keratoplasty

open access: yesTherapeutic Advances in Ophthalmology, 2020
The greatest advantage of deep anterior lamellar keratoplasty over full-thickness corneal transplantation is the elimination of graft failure caused by endothelial rejection.

Impaired Function of Peripherally Induced Regulatory T Cells in Hosts at High Risk of Graft Rejection

open access: yesScientific Reports, 2016
Regulatory T cells (Tregs) are crucial for allograft survival. Tregs can be divided into thymus-derived natural Tregs (tTregs) and peripherally-derived induced Tregs (pTregs).

Time- and Space-Modulated Raman Signals in Graphene-based Optical Cavities [PDF]

open access: yesJournal of Optics, vol. 15, 114010 (2013), 2013
We present fabrication and optical characterization of micro-cavities made of multilayer graphene (MLG) cantilevers clamped by metallic electrodes and suspended over Si/Si02 substrate. Graphene cantilevers act as a semi-transparent mirrors closing an air-wedge optical cavity.

Mechanisms of graft rejection after lung transplantation

open access: yesCurrent Opinion in Organ Transplantation, 2016
Purpose of review To date, outcomes after lung transplantation are far worse than after transplantation of other solid organs. New insights into mechanisms that contribute to graft rejection and tolerance after lung transplantation remain of great ...

Risk Factors of Rejection in Renal Transplant Recipients: A Narrative Review

open access: yesJournal of Clinical Medicine, 2022
Multiple factors influence graft rejection after kidney transplantation. Pre-operative factors affecting graft function and survival include donor and recipient characteristics such as age, gender, race, and immunologic compatibility.

HLA Antibody Incompatible Renal Transplantation: Long-term Outcomes Similar to Deceased Donor Transplantation

open access: yesTransplantation Direct, 2021
Background. HLA incompatible renal transplantation still remains one of best therapeutic options for a subgroup of patients who are highly sensitized and difficult to match but not much is known about its long-term graft and patient survival.

Macrophage subpopulations and their impact on chronic allograft rejection versus graft acceptance in a mouse heart transplant model

open access: yesAmerican Journal of Transplantation, 2018
Macrophages infiltrating the allografts are heterogeneous, consisting of proinflammatory (M1 cells) as well as antiinflammatory and fibrogenic phenotypes (M2 cells); they affect transplantation outcomes via diverse mechanisms.

Graft-derived cell-free DNA, a noninvasive early rejection and graft damage marker in liver transplantation: A prospective, observational, multicenter cohort study

open access: yesPLoS Medicine, 2017
Background Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker.
