Abstract
BACKGROUND The lack of noninvasive biomarkers for graft rejection remains a challenge for the accurate monitoring of vascularized composite allotransplants. Viral vector-mediated gene transfer is a promising method for preventing graft rejection. In this study, we aimed to establish the expression profile of microRNAs (miRNAs) in skin flap allotransplantation, with or without gene transfer, and determine the potential role of several miRNAs as biomarkers of acute rejection and immune tolerance. METHODS An abdominal epigastric flap was transplanted from SD (RT1a) to Wistar rats (RT1Au). The adenoviral interleukin 10 (vIL-10) gene was transferred to the experimental group via flap pedicle injection. Postoperatively, flap appearance, hematoxylin and eosin staining, immunohistochemical staining, and miRNA expression analyses were performed. RESULTS The viral IL-10 gene-treated group showed improved flap survival and reduced acute rejection response compared with the control group. On postoperative day 7, IL-10 expression in the flap was identified using immunohistochemistry and real-time polymerase chain reaction. The expression of miR-191a, miR-31a, miR-16, and miR-3473 was upregulated in the skin tissue, and that of miR-484, miR-132, miR-139, miR-150, and miR-6216 was upregulated in the serum. CONCLUSION AV IL-10 gene transfer could be an effective immunosuppressive strategy for the prevention of skin flap allograft rejection. Additionally, some miRNAs were upregulated in the experimental group, serving as potential biomarkers of immune tolerance.

Abstract
Aim The development of microsurgery has greatly advanced vascularized composite allotransplantation (VCA). However, like organ transplantation, VCA is also limited by acute rejection, and concerns regarding long-term survival and function of the transplanted graft. Therefore, it is necessary to elucidate the molecular mechanisms underlying acute rejection caused by VCA, in order to improve patient survival. Methods Firstly, we used Brown Norway rats and Lewis rats to construct animal model of VCA. Regularly record the appearance changes of all subjects. Specimens were collected for histological examination, microRNAs (miRNAs) sequencing and RT-qPCR verification when acute immune rejection occurred. Then, bioinformatics analysis was employed to predict miRNA related molecules and pathway information. Finally, differentially expressed miRNAs were tested and verified. Results MiRNAs are small non coding RNA transcripts that regulate gene expression at the post-transcriptional level. Studies have shown that miRNAs are involved in immune regulation and several miRNAs have been identified that are potential diagnostic and prognostic biomarkers of acute rejection. In this study, we found that the expression levels of rno-miR-21-5p, rno-miR-340-5p, rno-miR-1-3p and rno-miR-195-5p are significantly associated with acute rejection following VCA. Conclusion This miRNA signature can potentially an auxiliary diagnostic indicator of rejection, which can help clinicians adjust the immunosuppressive program in time during acute rejection.

Abstract
Vascularised composite allograft (VCA) transplantation is now a feasible reconstructive option for patients who have suffered significant soft tissue injuries. However, despite numerous technical advances in the field over two decades, a number of challenges remain, not least the management of transplant rejection. Part of the difficulty faced by clinicians is the early recognition and prevention of acute rejection episodes. Whilst this is potentially easier in VCAs than solid organ transplants, due to their visible skin component, at present the only validated method for the diagnosis of acute rejection is histological examination of a tissue biopsy. The aim of this review article is to provide an evidence-based overview of progress in the field of VCA biomarker discovery, including immune cell subsets, immune cell effector pathways, and circulating markers of allograft damage, and to discuss future challenges in the field.

Transplant Rev (Orlando) 2020; 34:100566. [PMID: 32682704 DOI: 10.1016/j.trre.2020.100566] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 06/23/2020] [Accepted: 06/30/2020] [Indexed: 12/24/2022]
Abstract
Nowadays, solid organ transplantation (SOT) is an established treatment for patients with end-organ dysfunction, which dramatically improves the quality-of-life. Vascularized composite allotransplants (VCAs) including hand and face have been reported worldwide over the last 20 years. However, VCAs, differently to SOT, are life-enhancing instead of life-saving and are not routinely performed due to the risk of immune rejection and the adverse effects of immunosuppression. Over the past decade, although considerable improvements in short-term outcomes after allotransplantation have been registered, these results have not been translated into major progress in long-term allograft acceptance and patient survival. Recently active researches in the field of biomarker discovery have been conducted to develop individualized therapies for allograft recipients. MicroRNAs (miRNAs) are a small noncoding RNAs functioning as critical regulators of gene and protein expression by RNA interference. They have been connected in numerous biological processes and diseases. Due to their immunomodulatory functions, miRNAs have been amended as potential diagnostic and prognostic biomarker for the detection of rejection in allotransplantation. Due to their specific circulating expression profile, they could act as noninvasive predictive tools for rejection that may help clinicians in an early adjustment of the immunosuppression protocol during acute rejections episodes. Indeed, specific anti-sense oligonucleotides suppressing miRNAs expressed in rejection could reduce the rejection rate in allografts and decrease the use of immunosuppressants. We present a literature review of the immunomodulatory properties and characteristics of miRNAs. We will summarize the current knowledge on miRNAs as potential biomarkers for allograft rejection and possible application in allotransplantation monitoring. Finally, we will discuss the advances in preclinical miRNA-based therapies for immunosuppression.
