Special Issue Information

Dear Colleagues,

The era of success in solid organ transplantation started with the clarification of the immunologic mechanisms that govern graft rejection and induction of immune tolerance. The advent of immunosuppressive therapy resulted in sustained prolonged graft and patient survival.

Cellular and humoral rejection in liver transplantation is a factor that threatens long-term graft survival. Furthermore, idiopathic graft fibrosis in a patient with, a seemingly uneventful postoperative course, is a major problem that is occasionally encountered. Subclinical cellular and humoral rejection may be the underlying mechanism of idiopathic graft fibrosis. However, the evidence regarding this theory is inconclusive.

Although there are many research teams around the world working on the mechanisms of immune responses in liver transplantation, the majority of transplantation research mainly focuses on the technical aspects of the procedure.  

It is our opinion that all the research in the field of transplant immunology should be concentrated on a single or a series of concise contemporary issues. Together with this objective in mind, we invite colleagues around the world to submit their basic science and original research studies, and review articles to this Special Issue entitled “Cellular and Molecular Mechanisms that Control and Regulate Immune Responses after Liver Transplantations” to be published in Vaccines, which has a high impact and is a highly respected journal in the field. We welcome molecular and basic science research as well as clinical observations and experiences in the field.

We hope that researchers in the field will have the highest interest in our special. We are looking forwards to all of the studies being submitted to our Special Issue.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Vaccines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background: Inflammation and the associated immune pathways are among the most important factors in liver regeneration after living donor hepatectomy. Various biomarkers, especially liver function tests, are used to show liver regeneration. The aim of this study was to evaluate the course of liver regeneration following donor hepatectomy (LDH) by routine and regeneration-related biomarkers. Method: Data from 63 living liver donors (LLDs) who underwent LDH in Inonu University Liver Transplant Institute were prospectively analyzed. Serum samples were obtained on the preoperative day and postoperative days (POD) 1, 3, 5, 10, and 21. Regenerative markers including alfa-fetoprotein (AFP), des carboxy prothrombin (DCP), ornithine decarboxylase (ODC), retinol-binding protein 4 (RBP4), and angiotensin-converting enzyme isotype II (ACEII) and liver function tests including alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP) and total bilirubin levels were all analyzed. Results: The median age of the LLDs was 29.7 years and 28 LLDs were female. Eight LLDs developed postoperative complications requiring relaparotomy. The routine laboratory parameters including AST (<0.001), ALT (<0.001), ALP (<0.001), and total bilirubin (<0.001) showed a significant increase over time until postoperative day (POD) 3. For the regeneration-related parameters, except for the RBP4, all parameters including ACEII (p = 0.006), AFP (p = 0.002), DCP (p = 0.007), and ODC (p = 0.002) showed a significant increase in POD3. The regeneration parameters showed a different pattern of change. In right-lobe liver grafts, ACEII (p = 0.002), AFP (p = 0.035), and ODC (p = 0.001) showed a significant increase over time. DCP (p = 0.129) and RBP4 (p = 0.335) showed no significant changes in right-lobe liver grafts. Conclusions: Regenerative markers are increased in a sustained fashion following LDH. This is more prominent following right-lobe grafts which are indicative of progenitor-associated liver regeneration. Full article
