BACKGROUND: Follicular lymphoma (FL) is an indolent non-Hodgkin lymphoma that has a risk of transformation to more aggressive lymphoma. Relatively little is known about the non-malignant B-cell and T-cell subset composition within the tumor microenvironment and whether altered phenotypes are associated with patterns of lymphoma B-cell heterogeneity. METHODS: Two mass cytometry (CyTOF) panels were designed to immunophenotype B and T cells in FL tumors. Populations of malignant B cells, non-malignant B cells, and T cells from each FL tumor were identified and their phenotypes compared to B and T cells from healthy human tonsillar tissue...

Natural killer (NK) cell licensing status depends on clonal expression of inhibitory killer cell immunoglobulin-like receptors (iKIR) and short term HLA environment. Licensed NK cells are more efficient in tumor killing than unlicensed NK cells. Cognate KIR-HLA pairs in hematopoietic stem cell transplant (HSCT) donor and recipient are decisive for the possible change in the NK cell licensing status after HSCT. We assessed clinical outcomes in 297 patients with lymphoproliferative or myeloproliferative malignancies, or myelodysplastic syndrome in a model with upward licensing, downward resetting, and unchanged licensing genetics status after T cell replate HSCT from unrelated donors...

OBJECTIVE: Shared epitope (SE)-coding DRB1 alleles are associated with bone erosion in several diseases, including rheumatoid arthritis (RA) and periodontal disease (PD), but the underlying mechanism is unknown. We have recently identified the SE as an osteoclast-activating ligand. To better understand the biological effects of the SE in vivo, here we sought to determine whether it can facilitate spontaneous bone damage in naïve mice. METHODS: 3-month old naïve transgenic mice that carry the human SE-coding allele DRB1*04:01, or a SE-negative allele DRB1*04:02 were studied...

BACKGROUND: Large granular lymphocyte (LGL) expansion occasionally occurs after allogeneic stem cell transplantation (allo-SCT), and is thought to be a good prognostic sign that is associated with a lower relapse rate. However, there have been no reports of late graft failure (LGF) due to graft rejection in association with oligoclonal LGL expansion. We herein report a case of LGF associated with the transient expansion of recipient-derived T-LGL after allo-SCT. CASE REPORT: A 65-year-old man underwent peripheral blood stem cell transplantation (PBSCT) from his human leukocyte antigen (HLA)-haploidentical son for the treatment of acute myeloid leukemia, which had evolved from a myelodysplastic syndrome (MDS)...

BACKGROUND: Combined kidney and auxiliary orthotopic liver transplantation from the same donor is used to treat highly sensitized renal transplant recipients. Auxiliary liver can protect the transplanted kidney against hyperacute rejection. METHODS: In the current case, combined kidney and splenic fossa auxiliary heterotopic liver transplantation was performed from the same donor for a highly sensitized recipient without preoperative preconditioning. No postoperative hyperacute rejection occurred...

Although donor-specific antibodies are regarded as a contraindication for kidney transplantation, the data available for combined liver and kidney transplantation (cLKTx) are scarce, and there is no established therapeutic approach for this category of transplant recipients. De novo use of everolimus and a reduced dose of calcineurin inhibitor reportedly provides excellent kidney function compared with a standard regimen containing a calcineurin inhibitor. This strategy, however, has been applied in only some recipient categories...

BACKGROUND: In kidney transplantation, long-term graft survival has improved over the last few decades. Study to understand ultralong-term graft survival with graft functioning is rare, but a few researchers have tried to explain the factors involved in long-term graft survival. In this report, we explore the predictive factors that can be involved in ultralong-term graft survival. MATERIAL AND METHODS: Immunologic evaluations of the patients were performed using crossmatch (XM), serological, and high-resolution HLA typing for 8 loci...

BACKGROUND AND OBJECTIVES: Long-term morbidity and mortality after heart transplantation (HTx) remain very high. Several reports have suggested that anti-HLA antibodies (anti-HLA-AB) detected after HTx might be associated with poor survival, but the implication of isolated anti-HLA-AB is still under debate. The aim of the study was to analyze the incidence of de novo anti-HLA-AB and whether they are associated with adverse events after HTx. METHODS: This retrospective study analyzed the presence of anti-HLA-AB assessed by fluorimetry (Luminex) and quantified by a single-antigen bead assay in 119 HTx patients...

INTRODUCTION: Information about the consequences of de novo donor-specific anti-human leukocyte antigen (DSA) antibody development in the long term after adult liver transplantation (LT) is scarce. We conducted a cross-sectional study in LT patients with a follow-up of at least 6 years. METHODS: A total of 28 adult LT patients were included, with a median follow-up of 77 months (range, 63 to 96) and without preformed anti- human leukocyte antigen (HLA) antibodies prior to LT...

BACKGROUND: Nonrenal transplantation could cause a progressive deterioration in renal function until need dialysis. It is important to know if these patients increased their risk to develop de novo donor-specific anti-HLA antibody (DSA) after starting hemodialysis (HD) and if so, try to find the mechanism. MATERIAL AND METHODS: In this double-phase study, we first analyzed the incidence of development DSA in nonrenal transplant recipients after starting HD by a retrospective study...

BACKGROUND: Although acute vascular rejection (AVR) is associated with a high risk of graft loss, it remains unclear whether AVR with accompanied cellular or humoral rejection (AHR) has dissimilar outcomes. The aim of this study was to examine the association between subtypes of AVR and graft loss. METHODS: We assessed patients who provided biopsy samples for acute allograft rejection from 1998 to 2014. To investigate distinct rejection patterns, we retrospectively assessed rejection episodes with review of graft histology as well as donor-specific anti-HLA antibodies when available...

INTRODUCTION: The definition of antibody-mediated rejection (AMR) is based on serologic (presence and/or development of donor-specific anti-HLA antibodies [DSAs]) and histologic (C4d deposition and endothelial damage) criteria. However, several cases of AMR have been described without C4d deposition, and other cases of histologic AMR without DSAs, which could be driven by other non-HLA alloantibodies such as anti-MICA or anti-angiotensin II type I receptor (AT1R). Here we studied clinical and histologic humoral rejection in kidney transplant recipients without evidence of anti-HLA antibodies...

BACKGROUND: Kidney transplantation is the better option for end-stage renal disease (ESRD), but for patients with human leukocyte antigen (HLA) sensitization, the wait times are significantly longer than for patients without antibodies. Many desensitization protocols have been described involving strong immunosuppression, the use of apheresis, and B-cell-modulating therapies. We have designed a desensitization protocol from day 0 for deceased donor kidney transplantation. Our aim was to present our initial experience with five kidney transplant patients...

Access to kidney transplantation for patients with high levels of antibodies against HLA is a major challenge. This issue makes it difficult to detect compatible donors for those patients in a certain geographical area. Consequently, hypersensitized patients remain on the waiting list for long periods and their quality of life deteriorates. Our purpose was to increase access to transplantation for highly sensitized patients by developing a national priority allocation system based on virtual crossmatch. Between June 15, 2015, and May 15, 2016, 675 patients on the kidney transplant waiting list with calculated panel-reactive antibodies ≥98% and undergoing dialysis for at least 12 months were included in the study; 86...

Non-heart-beating donors (NHBD) are an increasing source of organs for kidney transplantation (KT) compared with donation after brain death (DBD), but the results in each regional transplantation program require local analysis. We compared 164 KT from NHBD (83 Maastrich type II A-B [T2] and 81 type III [T3]) with 328 DBD controls. NHBD kidneys were implanted with less cold ischemia, mean time on renal replacement therapy for NHBD recipients before transplantation was less too, and a higher proportion of thymoglobulin was also used...

The aim of the current study was to characterize the anti-HLA antibodies before and after pancreatic islet or pancreas transplantation. We assessed the risk of anti-donor-specific antibody (DSA) sensitization in a single-center, retrospective clinical study at Geneva University Hospital. Data regarding clinical characteristics, graft outcome, HLA mismatch, donor HLA immunogenicity, and anti-HLA antibody characteristics were collected. Between January 2008 and July 2014, 18 patients received islet transplants, and 26 patients received a pancreas transplant...

Umbilical cord blood-derived mononuclear cell (UCB-MNC) transplants improve recovery in animal spinal cord injury (SCI) models. We transplanted UCB-MNCs into 28 patients with chronic complete SCI in Hong Kong (HK) and Kunming (KM). Stemcyte Inc. donated UCB-MNCs isolated from human leukocyte antigen (HLA 4:6)-matched UCB units. In HK, four patients received four 4-l injections (1.6 million cells) into dorsal entry zones above and below the injury site, and another four received 8-l injections (3.2 million cells)...

Airway epithelial cells reduce cytosolic ATP content in response to treatment with S. aureus alpha-toxin (hemolysin A, Hla). This study was undertaken to investigate whether this is due to attenuated ATP generation or to release of ATP from the cytosol and extracellular ATP degradation by ecto-enzymes. Exposure of cells to rHla did result in mitochondrial calcium uptake and a moderate decline in mitochondrial membrane potential, indicating that ATP regeneration may have been attenuated. In addition, ATP may have left the cells through transmembrane pores formed by the toxin or through endogenous release channels (e...

Herpesvirus entry into host cells is mediated by multiple virally encoded receptor binding and membrane fusion glycoproteins. Despite their importance in host cell tropism and associated disease pathology, the underlying and essential interactions between these viral glycoproteins remain poorly understood. For Epstein-Barr virus (EBV), gHgL/gp42 complexes bind HLA class II to activate membrane fusion with B cells, but gp42 inhibits fusion and entry into epithelial cells. To clarify the mechanism by which gp42 controls the cell specificity of EBV infection, here we determined the structure of gHgL/gp42 complex bound to an anti-gHgL antibody (E1D1)...
