Species-specific antibodies (Ab) for the measurement of immunoglobulins (Ig) are valuable tools for determining the humoral immune status of threatened and endangered wildlife species such as dugongs. However, no studies have reported antibody reagents against dugong immunoglobulin. The object of this study was to develop an Ab with specificity for dugong IgG and apply this tool to survey total IgG levels in plasma samples from a live wild population of dugongs in southern Queensland, Australia. Dugong IgG was isolated from plasma by protein A/G column chromatography and a polyclonal antiserum was successfully raised against the dugong IgG through immunization of mice...

OBJECTIVE: Current treatments cannot completely eradicate HIV-1 owing to the presence of latently infected cells which harbor transcriptionally silent HIV-1. However, defucosylated antibodies can readily kill latently infected cells after their activation to express envelope glycoprotein (Env) through antibody-dependent cellular cytotoxicity (ADCC). We herein aimed to test a defucosylated bispecific multivalent molecule consisting of domain-antibody and single-domain CD4, LSEVh-LS-F, for its HIV-1 neutralizing activity and ADCC against the reactivated latently infected cells, compared with the non-defucosylated molecule LSEVh-LS...

BACKGROUND: Although the hospitalization rate at early period of kidney transplantation (KT) is still high, the association between the hospitalization within 1 year after KT and graft survival is unclear. We investigated the incidence and causes of hospitalization and clinical outcome of the patients hospitalized within 1 year after KT. METHODS: We retrospectively analyzed 174 KT recipients (KTRs) hospitalized within 1 year after KT between 2013 and 2015. RESULTS: Among them, 84 (48%) KTRs were admitted within 1 year after KT, and the number of hospitalizations was 116...

Around 70% of circulating alpha-2-antiplasmin (α2AP), the main natural plasmin inhibitor, is N-terminally cleaved between residues Pro12 and Asn13 by antiplasmin-cleaving enzyme. This converts native Met-α2AP into the more potent fibrinolysis inhibitor Asn-α2AP. The Arg6Trp (R6W) polymorphism affects the N-terminal cleavage rate of Met-α2AP in a purified system, with ~8-fold faster conversion of Met(R6)-α2AP than Met(W6)-α2AP. To date, assays to determine N-terminally intact Met-α2AP in plasma have been limited to an ELISA that only measures Met(R6)-α2AP...

BACKGROUND: Risk assessment in heart transplantation is critical for candidate selection, but current models inadequately assess individual risk of postoperative mortality. We sought to identify risk factors and develop a scoring system to predict mortality following heart transplantation in children. METHODS: The records of patients undergoing heart transplantation at our institution from 2010 - 2016 were reviewed. Clinical characteristics were recorded and compared between survivors and non-survivors...

The HIV-1 Gag precursor protein (p55) is the main structural protein comprising the matrix (MA/p17), capsid (CA/p24), and nucleocapsid (NC/p7) proteins, and is uniquely responsible for virion assembly within the virus life cycle. The MA protein plays a critical role in plasma membrane targeting and envelope glycoprotein (Env) uptake during virion assembly. Yet, when viral infection occurs, the MA protein may also be involved in virion uncoating, dissociating from the plasma membrane, and participating in the nuclear importation process...

INTRODUCTION: HLA-sensitized patients are penalized both in the access to kidney transplantation (KT) and, once transplanted, in the incidence of rejections and long-term allograft survival despite aggressive induction and maintenance therapy. METHODS: This study retrospectively evaluates the impact of combining T- and B-cell-depleting agents and intravenous immunoglobulin for induction therapy in 45 highly sensitized KT patients (anti-panel reactive antibodies >60%, positive flow cytometry crossmatch or donor specific antibodies at the time of transplantation)...

Cardiovascular disease after transplantation: an emerging role of the immune system. Cardiovascular disease after transplantation remains a major concern. Little is known about what drives the increased cardiovascular risk in transplant recipients apart from traditional risk factors. The immune system is involved in the pathogenesis of hypertension, atherosclerosis, and coronary artery disease in the general population. Recently, inhibition of interleukin 1-β by canakinumab versus placebo decreased the incidence of cardiovascular events...

Lipoarabinomannan (LAM), the major antigenic glycolipid of Mycobacterium tuberculosis , is an important immunodiagnostic target for detecting tuberculosis (TB) infection in HIV-1-coinfected patients, and is believed to mediate a number of functions that promote infection and disease development. To probe the human humoral response against LAM during TB infection, several novel LAM-specific human mAbs were molecularly cloned from memory B cells isolated from infected patients and grown in vitro. The fine epitope specificities of these Abs, along with those of a panel of previously described murine and phage-derived LAM-specific mAbs, were mapped using binding assays against LAM Ags from several mycobacterial species and a panel of synthetic glycans and glycoconjugates that represented diverse carbohydrate structures present in LAM...

Chronic active hepatitis B infection (HBV) has been implicated in lymphomagenesis of non-Hodgkin lymphoma (NHL). Treatment of cancer including NHL with chemotherapy or immunotherapy can lead to HBV reactivation in previously infected patients. Serological testing of HBV prior to initiation of this therapy is recommended by several national and international medical agencies and expert panels. Patients with positive hepatitis B surface antigen (HBsAg) and anti-hepatitis B core antibody (anti-HBc ab) need to start antiviral therapy with entecavir or tenofovir prior to initiation of chemotherapy or immunotherapy and continue this treatment for 6 to 12 months after completion of cancer therapy to avoid late HBV reactivation...

The use of chimeric molecules fusing several antigenic determinants is a promising strategy for the development of low-cost, standardized and reliable kits to determine specific antibodies. In this study, we designed and assessed a novel recombinant chimera that complements the performance of our previously developed chimera, CP1 [FRA and SAPA antigens (Ags)], to diagnose chronic Chagas disease. The new chimeric protein, named CP3, is composed of MAP, TcD and TSSAII/V/VI antigenic determinants. We compared the performance of both chimeric Ags using a panel of 67 Trypanosoma cruzi-reactive sera and 67 non-reactive ones...

INTRODUCTION: Some factors affect the pancreas of a marginal donor, and although their influence on graft survival has been determined, there is an increasing consensus to accept marginal organs in a controlled manner to increase the pool of organs. Certain factors related to the recipient have also been proposed as having negative influence on graft prognosis. The objective of this study was to analyze the influence of these factors on the results of our simultaneous pancreas-kidney (SPK) transplantation series...

INTRODUCTION: Approximately 10% to 30% of patients on renal transplant waiting lists are sensitized, which gives them more time on the waiting list. Transplantation in this setting has a greater risk of rejection and decreased graft survival. New strategies of donor allocation through virtual crossmatching and optimization of immunosuppressive therapies in induction and maintenance have allowed the allocation of organs for this population, which in other circumstances would not be chosen for a kidney transplant...

Staphylococcal enterotoxins cause food poisoning of various degrees of severity. For milk and meat products, there is a high probability of contamination with staphylococcal enterotoxin H (SEH). In this regard specific and sensitive methods are required to be developed for its detection and monitoring. In this work, the gene seh was expressed and a preparation of recombinant toxin was obtained. Using hybridoma technology, a panel of high-affinity monoclonal antibodies (mAbs) to SEH was produced. The antibodies were characterized and shown to have no cross-reactivity towards the main staphylococcal enterotoxins (A, B, C1, D, E, G and I)...

Adenovirus (Ad) vectors are being investigated as vaccine candidates, but baseline antivector immunity exists in human populations to both human Ad (HuAd) and chimpanzee Ad (ChAd) vectors. In this study, we investigated the immunogenicity and cross-reactivity of a panel of recently described rhesus adenoviral (RhAd) vectors. RhAd vectors elicited T cells with low exhaustion markers and robust anamnestic potential. Moreover, RhAd vector immunogenicity was unaffected by high levels of preexisting anti-HuAd immunity...
